text: Central nervous system disease

text: Signs and symptoms[edit]

text: Every disease has different signs and symptoms. Some of them are persistent headache; pain in the face, back, arms, or legs; an inability to concentrate; loss of feeling; memory loss; loss of muscle strength; tremors; seizures; increased reflexes, spasticity,  tics; paralysis; and slurred speech. One should seek medical attention if affected by these.

text: Causes[edit]

text: Trauma[edit]

text: Any type of traumatic brain injury (TBI) or injury done to the spinal cord can result in a wide spectrum of disabilities in a person. Depending on the section of the brain or spinal cord that suffers the trauma, the outcome may be anticipated.

text: Infections[edit]

text: Infectious diseases are transmitted in several ways. Some of these infections may affect the brain or spinal cord directly. Generally, an infection is a disease that is caused by the invasion of a microorganism or virus.

text: Degeneration[edit]

text: Degenerative spinal disorders involve a loss of function in the spine. Pressure on the spinal cord and nerves may be associated with herniation or disc displacement. Brain degeneration also causes central nervous system diseases. Studies have shown that obese people may have severe degeneration in the brain due to loss of tissue affecting cognition.

text: Structural defects[edit]

text: Common structural defects include birth defects,[4] anencephaly, hypospadias, and spina bifida. Children born with structural defects may have malformed limbs, heart problems, and facial abnormalities.

text: Defects in the formation of the cerebral cortex include microgyria, polymicrogyria, bilateral frontoparietal polymicrogyria, and pachygyria.

text: Tumors[edit]

text: A tumor is an abnormal growth of body tissue. In the beginning, tumors can be noncancerous, but if they become malignant, they are cancerous. In general, they appear when there is a problem with cellular division. Problems with the body's immune system can lead to tumors.

text: Autoimmune disorders[edit]

text: An autoimmune disorder is a condition where in the immune system attacks and destroys healthy body tissue. This is caused by a loss of tolerance to proteins in the body, resulting in immune cells recognising these as 'foreign' and directing an immune response against them.

text: Stroke[edit]

text: A stroke is an interruption of the blood supply to the brain. Approximately every 40 seconds, someone in the US has a stroke.[5] This can happen when a blood vessel is blocked by a blood clot or when a blood vessel ruptures, causing blood to leak to the brain. If the brain cannot get enough oxygen and blood, brain cells can die, leading to permanent damage.

text: Functions[edit]

text: Spinal cord[edit]

text: The spinal cord transmits sensory reception from the peripheral nervous system.[6] It also conducts motor information to the body's skeletal muscles, cardiac muscles, smooth muscles, and glands. There are 31 pairs of spinal nerves along the spinal cord, all of which consist of both sensory and motor neurons.[6] The spinal cord is protected by vertebrae and connects the peripheral nervous system to the brain, and it acts as a "minor" coordinating center.

text: Brain[edit]

text: The brain serves as the organic basis of cognition and exerts centralized control over the other organs of the body. The brain is protected by the skull; however, if the brain is damaged, significant impairments in cognition and physiological function or death may occur.

text: Diagnosis[edit]

text: Types of CNS disorders[edit]

text: This section is missing information about a number of brain disorders[3][7] that not currently listed here. Please expand the section to include this information. Further details may exist on the talk page. (July 2016)

text: Addiction[edit]

text: Addiction is a disorder of the brain's reward system which arises through transcriptional and epigenetic mechanisms and occurs over time from chronically high levels of exposure to an addictive stimulus (e.g., morphine, cocaine, sexual intercourse, gambling, etc.).[8][9][10][11]

text: Arachnoid cysts[edit]

text: Arachnoid cysts are cerebrospinal fluid covered by arachnoidal cells that may develop on the brain or spinal cord.[12] They are a congenital disorder, and in some cases may not show symptoms. However, if there is a large cyst, symptoms may include headache, seizures, ataxia (lack of muscle control), hemiparesis, and several others. Macrocephaly and ADHD are common among children, while presenile dementia, hydrocephalus (an abnormality of the dynamics of the cerebrospinal fluid), and urinary incontinence are symptoms for elderly patients (65 and older).

text: Attention deficit/hyperactivity disorder (ADHD)[edit]

text: ADHD is an organic disorder of the nervous system.[13][14][15][16] ADHD, which in severe cases can be debilitating,[17] has symptoms thought to be caused by structural as well as biochemical imbalances in the brain; in particular, low levels of the neurotransmitters dopamine and norepinephrine,[18] which are responsible for controlling and maintaining attention and movement. Many people with ADHD continue to have symptoms well into adulthood.[19] Also of note is an increased risk of the development of Dementia with Lewy bodies, or (DLB), & a direct genetic association of Attention deficit disorder to Parkinson's disease[20][21] two progressive, and serious, neurological diseases whose symptoms often occur in people over age 65.[19][22][23][24]

text: Autism[edit]

text: Autism is a neurodevelopmental disorder that is characterized by restricted and repetitive patterns of behavior and persistent deficits in social interaction and communication.[7]

text: Bipolar disorder[edit]

text:
Bipolar disorder is a serious illness of the nervous system.[25] Symptoms can include both signs of major depression & mania. Mood swings from the
highs of mania to the lows of deep depression usually occurs over several weeks to months. New research suggests that bipolar disorder is actually a neurological disease genetically related to Parkinson's disease[26]

text: Catalepsy[edit]

text: Catalepsy is a nervous disorder characterized by immobility and muscular rigidity, along with a decreased sensitivity to pain. Catalepsy is considered a symptom of serious diseases of the nervous system (e.g., Parkinson's disease, Epilepsy, etc.) rather than a disease by itself. Cataleptic fits can range in duration from several minutes to weeks. Catalepsy often responds to Benzodiazepines (e.g., Lorazepam) in pill & I.V. form.[27]

text: Depression[edit]

text: Major depressive disorder, otherwise known as depression, is a disorder that is characterized by a pervasive and persistent low mood that is accompanied by low self-esteem and by a loss of interest or pleasure in normally enjoyable activities.

text: Encephalitis[edit]

text: Encephalitis is an inflammation of the brain. It is usually caused by a foreign substance or a viral infection. Symptoms of this disease include headache, neck pain, drowsiness, nausea, and fever. If caused by the West Nile virus,[28] it may be lethal to humans, as well as birds and horses.

text: Epilepsy/Seizures[edit]

text: Epilepsy is an unpredictable, serious, and potentially fatal disorder of the nervous system, thought to be the result of faulty electrical activity in the brain. Epileptic seizures result from abnormal, excessive, or hypersynchronous neuronal activity in the brain. About 50 million people worldwide have epilepsy, and nearly 80% of epilepsy occurs in developing countries. Epilepsy becomes more common as people age. Onset of new cases occurs most frequently in infants and the elderly. Epileptic seizures may occur in recovering patients as a consequence of brain surgery.[29]

text: Infection[edit]

text: A number of different pathogens (i.e., certain viruses, bacteria, protozoa, fungi, and prions) can cause infections that adversely affect the brain or spinal cord.

text: Locked-in syndrome[edit]

text: A medical condition, Locked-in syndrome usually resulting from a stroke that damages part of the brainstem, in which the body and most of the facial muscles are paralysed but consciousness remains and the ability to perform certain eye movements is preserved.

text: Meningitis[edit]

text: Meningitis is an inflammation of the meninges (membranes) of the brain and spinal cord. It is most often caused by a bacterial or viral infection. Fever, vomiting, and a stiff neck are all symptoms of meningitis.

text: Migraine[edit]

text: A chronic, often debilitating neurological disorder characterized by recurrent moderate to severe headaches, often in association with a number of autonomic nervous system symptoms.

text: Multiple sclerosis[edit]

text: Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease, meaning that the myelin sheath of neurons is damaged. Symptoms of MS include visual and sensation problems, muscle weakness, numbness and tingling all over, muscle spasms, poor coordination, and depression. Also patients with MS have reported extreme fatigue and dizziness, tremors, and bladder leakage.

text: Neurodegenerative disorders[edit]

text: Alzheimer’s[edit]

text: Alzheimer's is a neurodegenerative disease typically found in people over the age of 65 years. Worldwide, approximately 24 million people have dementia; 60% of these cases are due to Alzheimer’s. The ultimate cause is unknown. The clinical sign of Alzheimer's is progressive cognition deterioration.

text: Huntington's disease[edit]

text: Huntington's disease is a degenerative neurological disorder that is inherited. Degeneration of neuronal cells occurs throughout the brain, especially in the striatum. There is a progressive decline that results in abnormal movements.[30] Statistics show that Huntington's disease may affect 10 per 100,000 people of Western European descent.

text: Parkinson's[edit]

text: Parkinson's disease, or PD, is a progressive illness of the nervous system. Caused by the death of dopamine-producing brain cells that affect motor skills and speech. Symptoms may include bradykinesia (slow physical movement), muscle rigidity, and tremors. Behavior, thinking, sensation disorders, and the sometimes co-morbid skin condition Seborrheic dermatitis are just some of PD's numerous nonmotor symptoms. Parkinson's disease, Attention deficit/hyperactivity disorder (ADHD) & Bi-polar disorder, all appear to have some connection to one another, as all three nervous system disorders involve lower than normal levels of the brain chemical dopamine(In ADHD, Parkinson's, & the depressive phase of Bi-polar disorder.) or too much dopamine (in Mania or Manic states of Bi-polar disorder) in different areas of the brain:[26][31][31][32][33]

text: Tourette's[edit]

text: Tourette's syndrome is an inherited neurological disorder. Early onset may be during childhood, and it is characterized by physical and verbal tics.TS often also includes symptoms of both OCD & ADHD indicating a link between the three disorders. The exact cause of Tourette's, other than genetic factors, is unknown.

text: Treatments[edit]

text: There is a wide range of treatments for central nervous system diseases. These can range from surgery to neural rehabilitation or prescribed medications.

text: Overview[edit]

text: This section needs expansion. You can help by adding to it. (November 2010)

tag: table

text: After 45 seasons, there now have been a total of 730 games televised by the Monday Night Football franchise.

tag: p

text: Scheduling problems[edit]

text: To avoid any scheduling unfairness where, just before the first playoff game, a team may have five days off and others six, there is no Monday night game during the final week of the regular season. From 2003 to 2005, one game was played on Thursday and another Monday under the Monday Night Football banner. Starting in 2006, when the series moved to cable, two games are played on the opening Monday night to capitalize on fan interest during "NFL Kickoff Weekend".

text: Monday night games early in the season are often highly anticipated since records are new, teams usually are showcasing fresh talent and potential, and storylines coming into the season are often played out as fans try to see if these hyped teams are up to form. Since no one knows during the first month of the season if a team is indeed good, or will rebound from a difficult start, interest is usually high for the first few weeks of the MNF season.

text: Since the MNF schedule is set in April and cannot be changed, the league and network cannot guarantee a late season matchup will have any significance or be highly anticipated. Teams thought to be good during the off-season could be out of playoff contention by the middle of the season; a prime example occurred in 1999, when the San Francisco 49ers and Atlanta Falcons both entered the season's final MNF game with 4–11 records. It had seemed like a good pre-season matchup since the Falcons had played in the previous season's Super Bowl and the 49ers coming into the 1999 season had posted 16 consecutive 10-win seasons. It is also possible for a team like the 1999 St. Louis Rams not to be scheduled for a Monday night game because of its dismal record the year before, and many other NFL teams (such as the 2004 San Diego Chargers, with zero primetime games) have had huge unforeseen turnarounds that result in lack of MNF attention (these teams generally receive multiple MNF spots the year after their breakout success, which is great for viewers if those teams continue to play well, and not so great if they return to mediocrity or worse). However, the forecasting abilities of the NFL's scheduling officials have exhibited uncanny proficiency. Many MNF games occurring later in the season feature at least one team that is either headed to the playoffs or must win the MNF game to clinch a playoff spot.

text: The problem of having a national spotlight game which during the season's most critical weeks late in the year probably would not show the most important game of the week was long known by the league and network. As a result of this, the NFL wished to move the "Game of the Week" idea to Sunday nights as to make flex scheduling possible. This was a move which would ultimately mean the end of Monday Night Football on ABC (cable games are protected from the NFL's flexible scheduling rule adopted for the 2006–07 season; the new rule applies only to CBS, Fox, and NBC's Sunday night games). The league currently has no interest in expanding flexible scheduling to include Monday Night Football, citing the logistical issues of moving games back and forth between Sundays and Mondays.

text: Franchises with the most appearances[edit]

text: The franchise with the most Monday night appearances is the Miami Dolphins. The San Francisco 49ers won their record 48th Monday Night game with a 28–0 win over the Los Angeles Rams on September 12, 2016.

text: The most common Monday Night Football pairings are Broncos vs. Raiders (17 match-ups as of 2013[a]) and Cowboys vs. Redskins (met for a 17th time in 2015).

text: The defunct Candlestick Park in San Francisco currently holds the record for hosting the most Monday Night Football games, including its 36th and final Monday night game on December 23, 2013. Among the active stadiums following the conclusion of the 2013 season, Miami Gardens, Florida's Hard Rock Stadium has hosted the most games with 32.[5]

text: As entertainment[edit]

text: Monday Night Football has continued to provide as much entertainment as sports throughout its run. In addition to the extra cameras, the program has also pioneered technological broadcast innovations, such as the use of enhanced slow motion replays and computerized graphics.

text: Celebrity guests – such as former Vice President Spiro Agnew, singers Plácido Domingo and former Beatle John Lennon, President Bill Clinton, and even Kermit the Frog – were often featured during the game to "liven up" the broadcast. The December 9, 1974 contest featured a rare instance of two celebrities entering the booth, with Lennon being interviewed by Howard Cosell and California governor Ronald Reagan speaking with Frank Gifford, with Reagan explaining the rules of American football (off-camera) to Lennon as the game went along. However, the late 1990s and early 2000s saw an even more increased reliance on the entertainment factor. Some halftime shows, featuring popular music stars, were broadcast in their entirety rather than being ignored in favor of analysis of the game by the commentators, as in previous seasons.

text: In December 1980, one of the most memorable moments of MNF occurred when Cosell announced in a news flash that Lennon had been shot and killed in New York City. Monday Night Football was the first national broadcast to announce his death.

text: An advertisement during halftime on the October 19, 2015 game featured the world premiere of the third trailer of Star Wars: The Force Awakens.

text: 2006 summary[edit]

text: For its 2006 debut on ESPN, Williams, Jr. re-recorded the MNF opening theme with an all-star jam band that included among others Brian Setzer, Little Richard, Questlove, Joe Perry, Clarence Clemons, Rick Nielsen, Bootsy Collins, Charlie Daniels and Steven Van Zandt. The 2006 telecast generally began with a cinematic tease produced by Rico Labbe, Michael Sciallis and Jason Jobes. It was during one of these teases that Barack Obama spoofed his announcement for the 2008 Presidential candidacy in favor of his hometown Chicago Bears in their game against the St. Louis Rams.[6]

text: That year, the tease was followed by the show open produced by Los Angeles-based The Syndicate called "Transformation". It features computer-generated imagery showing a city being transformed into a football stadium and passers-by on the street turning into players, coaches, fans and officials set to an updated orchestral treatment of the "Heavy Action" theme song. The sequence began every week with a different celebrity walking down the street, picking up a glowing football helmet with the ESPN logo on the side and saying, "I'm ready for some football! Are you?", thus beginning the transformation process. Celebrities for 2006 included Arnold Schwarzenegger, Matthew Fox, Hugh Hefner, Paris Hilton, Spike Lee, Ashton Kutcher, Samuel L. Jackson, Ludacris, Jack Black, Kiefer Sutherland, James Belushi, Ben Stiller, Tyra Banks, Carmen Electra and Eva Longoria.

text: In addition, celebrities returned in full force to the booth, though this proved to be the major criticism of ESPN's first MNF season. On the opening weekend, Arnold Schwarzenegger, another celebrity-turned-California governor, was in the booth at McAfee Coliseum in Oakland, California; before that, Jamie Foxx appeared at FedExField in suburban Washington, D.C. Following them, celebrity appearances included NBA basketball superstar Dwyane Wade, Basketball Hall of Fame player Charles Barkley, NASCAR Cup Series driver Jeff Gordon, comedian Jimmy Kimmel (whose opening words to Joe Theismann were "how's the leg?"), actor Sylvester Stallone, film director Spike Lee, hip hop artist Jay-Z, and MNF theme singer Hank Williams Jr.

text: 2007 summary[edit]

text: ESPN scaled back to only one opening tease for the 2007 season. Williams Jr. and the all-star band returned, only this time they played in a "juke joint" set on a country road. The lead singer arrives in a GMC Yukon truck (GMC paid for product placement) with the license plate "BOCEPHUS", which is Williams' nickname. The Syndicate's computer-generated tease was dropped and replaced by short pre-taped films focusing on a team or player in the game. Some of them have featured actor Jamie Foxx.

text: The guest visits continued: Barkley returned to the booth on September 17 in Philadelphia. Other guests throughout the season included Kimmel (another returnee), Drew Carey, Miley Cyrus, Russell Crowe and Terry Bradshaw. In addition, Gordon was a halftime guest on the game just before the season-ending Ford 400 and was joined by teammate Jimmie Johnson.

text: At the end of each game, Williams returned to say, "See you in (city that is the site of the next week's game)." Both the open and close contain helmets of the participating teams, organized in the style of a concert poster.

text: 2008 summary[edit]

text: Despite the de-emphasis on entertainment on the overall telecast, ESPN did bring back Hank Williams, Jr. for his 20th season as part of the opening. This time, the opening sequence was set in a private residence. At the end of the song, Williams Jr. touched a foot pump, which supposedly contained the helmets of that night's participating teams. The helmets were launched from the home toward the stadium at which the game was held. Through computer-generated imagery, the helmets "land" at midfield during a live shot, and then explode. The "exploding helmets" gimmick was also used at various times in the 1980s and 1990s during the pre-game tease. Williams Jr. then appeared again at the end of the game to promote the next week's matchup.

text: ESPN also continued to promote upcoming albums through its use in bumper music. On September 29 (Baltimore Ravens at Pittsburgh Steelers), ESPN used "Another Way to Die", a duet between Alicia Keys and Jack White of the White Stripes – the song was part of the soundtrack for the 2008 film Quantum of Solace, then the latest in the James Bond series.

text: Monday Night Football celebrated its 600th game broadcast on October 20, 2008 in a game which the New England Patriots defeated the Denver Broncos, 41–7.

text: The 39th season of MNF ended on December 22, 2008, when the Bears beat the Green Bay Packers, 20–17, in overtime at home at Soldier Field in Chicago.

text: 2009 summary[edit]

text: The title sequence for the 40th season of Monday Night Football featured Hank Williams, Jr. seen on the steps of a building (presumably a museum), surrounded by dancers, football fans, and statues/busts – which, along with everyone else in the scene, begin to move and dance – patterned after those at the Pro Football Hall of Fame. The transition to Williams Jr. is a book, with the chapter number (in Roman numerals, sequentially with each week) and a tag line about the game to be played that night.

text: At the end of the song, Williams Jr. plugged in the cords, thereby launching animated "helmets" into space, from the building toward the stadium at which the game was held (with the exception of October 5, 2009, when the helmets zoomed towards Brett Favre instead), passing the International Space Station. As with the previous season (as mentioned above), the helmets "land" at midfield during a live shot and then crashed into each other. Williams Jr. appeared again at the end of the telecast to promote the following week's matchup. After that, the picture was freezeframed and the shot zoomed out to the book, which showed the freezeframed picture as part of a page. As this happened, the NFL end-of-game bumper music was played and the book closed, revealing a golden NFL logo on the back cover and signifying the end of the "chapter", or game. The scene was filmed in the summer of 2009 at The Parthenon in Nashville, Tennessee.

text: Before Williams Jr. appears, Frank Gifford gave a short vignette about a memorable moment in the history of Monday Night Football featuring one or both of the teams playing that night's game.

text: The 40th season of Monday Night Football ended on December 28, 2009 with the Minnesota Vikings–Chicago Bears game in Chicago, in which the Bears won in overtime, 36–30. The telecast ended with a vignette that featured Gifford taking a look back at highlights from the previous four decades – and the 40th season – of MNF, after which the book closed, signifying the end of the season. The 40th season had the highest season viewership for MNF since ESPN acquired the rights to the broadcast.[7]

text: 2010 summary[edit]

text: The opening for the 2010 season was identical to that used in 2009, except for the final scenes. This time, Williams Jr. turns a wheel filled with paint, with CGI colors blasting into the air, revealing the helmets containing logos of the participating teams – which stay on top of the building. In one other minor difference, the chapter numbers in the "book" were changed from Roman to Arabic numerals. Gifford provided new vignettes and the Parthenon scenes were repeated from the year before. The 2010 season marked Williams' 22nd as part of the telecast's open.

text: In an unusual coincidence, both games which had the New York Jets as a home team at New Meadowlands Stadium (now MetLife Stadium) were delayed because of heavy rain and lightning in the area. In the first instance, the September 13 game against the Baltimore Ravens, it was delayed 25 minutes; the second delay, prior to the October 11 contest against the Minnesota Vikings, lasted for 40 minutes. Prior to the September 13 game, the last ESPN telecast to encounter weather problems was on October 4, 1998 (a Sunday night) when lightning halted a game between the Seattle Seahawks and Kansas City Chiefs during the second quarter. The first delay forced ESPN to use ESPN2 for a game telecast, this time for the Chiefs' home opener against the San Diego Chargers. As in 2007, the broadcast was shifted to ESPN once the first game was over.

text: The game between the Jets and the Vikings was both Brett Favre's first game in East Rutherford since his only season there in 2008 and marked Randy Moss's return to the Vikings. Moss played only four games for Minnesota until he was waived on November 2.

text: 2011 summary[edit]

text: The opening sequence for the 2011 season was set in a closed-studio setting, with Hank Williams Jr. (in his 23rd year) performing with a band in front of a live audience with large video screens in the background. The end of the opening sequence featured the team logos of that night's participants transitioning into the new ESPN Monday Night Football logo before going to a live shot. On October 3, 2011, ESPN pulled the theme song after Williams appeared on the Fox News Channel program, Fox & Friends, where he compared a golf outing involving Barack Obama, John Boehner, Joe Biden and John Kasich to "Hitler playing golf with Netanyahu."[8][9] On October 6, 2011, it was announced that Williams would no longer be singing the theme song, and that "All My Rowdy Friends" would no longer be used as its theme, as Williams still owns the song. A statement from ESPN said that the network has "decided to part ways with Hank Williams Jr. We appreciate his contributions over the past years. The success of Monday Night Football has always been about the games and that will continue."[10] Williams commented on the matter: "After reading hundreds of e-mails, I have made my decision... By pulling my opening October 3, [ESPN] stepped on the toes of the First Amendment Freedom of Speech, so therefore me, my song, and All My Rowdy Friends are out of here. It's been a great run."[10] MNF did not have an opening sequence at all from Week 4 through the end of that season.

text: With Suzy Kolber reassigned to the new studio show NFL32, and Michele Tafoya having left ESPN for NBC Sunday Night Football, the sideline reporter position rotated between various reporters for the season.

text: For the second year in a row, and the third time overall, the beginning of the 10:15 p.m. Eastern Time game (Oakland Raiders at Denver Broncos) was shown on ESPN2 as the game that began at 7:00 p.m. Eastern Time (New England Patriots at Miami Dolphins) ran past the scheduled time period.

text: 2012 summary[edit]

text: Lisa Salters was named the permanent solo sideline reporter for the 2012 season. In addition, color commentator Ron Jaworski did not return to the program. As a result, Jon Gruden became the solo color commentator, with MNF going back to a two-man booth for the first time since its final season on ABC (2005). MNF's opening graphic sequence, which showed the helmet logos of the game's two participating NFL teams and then the program's logo, was seen before the Monday Night Football Launch segment.

text: 2013–14 summary[edit]

text: The opening animation sequence begins with an image of a 2014 GMC Sierra (GMC paid for product placement) and then goes into a timeline of historical events that occurred during the Monday Night Football era, including some highlights of MNF games from the previous 43 seasons up to 2012. At the end of the sequence, helmets featuring logos of that night's two participating teams are shown, followed by the various Monday Night Football logos used since the program's debut in 1970. The 80-second opening animation sequence, which also featured Pac-Man, Darth Vader and President Ronald Reagan, was created by actor/filmmaker Peter Berg.

text: A revision of the opening sequence was used for the 2014 season. Among the few changes, GMC's product placement promoted the automaker's line of Denali vehicles, while the sequence itself included some additional highlights of MNF games from the previous 44 seasons up to 2013.

text: 2015 summary[edit]

text: A 3D opening animation sequence is used for the 2015 season (46th season overall and tenth on ESPN). GMC's product placement once again promoted the automaker's line of Denali vehicles, including the Yukon Denali that is seen at the beginning. Also among the many changes is the highlights of MNF games — this time, they are set inside a computer-generated stadium using 3D imagery — from the previous 45 seasons up to 2014.

text: 2016 summary[edit]

text: After three years of using the timeline-themed open, MNF debuted a new 75-second, Hollywood-themed open on September 12, 2016 and it features ESPN's new MNF broadcast team — Sean McDonough (play-by-play), Jon Gruden (color) and Lisa Salters (sideline reporter) — and more than 20 current NFL stars and Pro Football Hall of Famers walking along a red carpet entrance lined by cheering fans and photographers taking pictures. It begins with a shot of a downtown stadium surrounded by skyscrapers, with a 2017 GMC Acadia (product placement again provided by GMC) displaying the location for that week's MNF game on its navigation system. The Acadia then heads to a glitzy red carpet at the stadium's entrance, where McDonough, Gruden and Salters exit the car, followed on the carpet by a flood of NFL players representing the past and present of MNF. Players then pose for pictures and wave to the crowd as they reach the stadium entrance. Josh Norman (Redskins), Larry Fitzgerald (Cardinals) and Rob Gronkowski (Patriots) are among the current players being represented in the open, with Franco Harris (Steelers), Jerry Rice (49ers), Barry Sanders (Lions) and Bruce Smith (Bills) among the past players being represented. For the Spanish-language version of the Hollywood-themed open, it features ESPN's Spanish-language MNF broadcast team — Álvaro Martín (play-by-play), Raúl Allegre (color) and John Sutcliffe (sideline reporter) as well as the current Hispanic NFL players and the team of the Latin American version of NFL Live led by Ciro Procuna.

text: 2017 summary[edit]

text: MNF returned to two teases for the first time since its first season on ESPN (2006). The Hollywood-themed open was repeated from the previous season, this time with the 2018 GMC Terrain being used as the automaker's product placement.

text: Also, Hank Williams, Jr. returned to MNF on September 11, 2017 with an all-new version of the iconic opening theme song, "All My Rowdy Friends Are Here on Monday Night" (used from 1989 to Week 3 of the 2011 season) and it appeared just before that night's New Orleans Saints-Minnesota Vikings game. The new version, which is seen just before the kickoff of each game, is a collaboration of Williams, Jr, country duo Florida Georgia Line, and R&B singer Jason Derulo.

text: Theme music[edit]

text: Hank Williams Jr. reworked his country music hit "All My Rowdy Friends Are Coming Over Tonight" to be included in the telecast's introduction as "All My Rowdy Friends Are Here on Monday Night" (the original introduction music was an organ-based piece called "Score", written by Charles Fox and recorded by Bob's Band). In addition, Edd Kalehoff modernized the classic "Heavy Action" theme in 1989.

text: For ABC's last MNF game in 2005, Williams Jr.'s rendition of "Turn Out the Lights, The Party's Over", closed the broadcast.[11]

text: Prior to 1997, Monday Night Football had a limited graphics package. A CGI-based intro began being used in 1984, with on-screen graphics still limited to basic text.[12][13] In 1988, the entire graphics package was updated significantly to be more in line with the rest of ABC Sports' presentations. That year, it introduced the "clashing helmets" intro, with on-screen graphics consisting of italicized text underlined in red.[14] It was updated in 1994, the year the network hosted Super Bowl XXIX, with a more box-like design.[15] A permanent score bug would not be introduced until 1997.

text: Monday Night Football began using a score bug in 1997, the second network to do so after Fox introduced the first regular on-screen scoring bug when it began airing NFL games in 1994. Prior to this, the graphics package was limited, but followed a basic "ketchup and mustard" color scheme of red and yellow. The first scorebug included team names, scores, time remaining, and displayed which quarter the game was in.[16] This design was used through the 1998 season.

text: ABC hosted Super Bowl XXXIV for 1999, and updated its graphics package to more closely resemble those of sister cable network ESPN. ABC began using extended abbreviations for team names (for example, "TENN", "VIKES", "PACK", and "FINS" instead of "TEN", "MIN", "GB", and "MIA"), as four-letter and five-letter abbreviations were used on ESPN coverage. The result was a larger scorebug with a more conventional font.[17] It was slightly modified in 2000 to have a border that was more in line with the red and yellow color scheme.[18]

text: The graphics for Monday Night Football were changed in the 2002 season, the year the network hosted Super Bowl XXXVII. The scorebug was a solid color, with a more rounded shape, and a horizontally compressed font. ESPN's graphics were no longer similar to those of ABC's (with ESPN instead using a gray and black design with rounded corners).[19] In 2005, the broadcast's final year on ABC, Monday Night Football began using a horizontal bar on the bottom of the screen rather than a scorebug, with all information being contained on a single line.[20]

text: After Monday Night Football moved to ESPN in 2006 (around the same time that ABC Sports rebranded as ESPN on ABC), ESPN changed its entire graphics package to a red and black design, while NFL coverage used a separate design. For NFL telecasts in 2006 and 2007, a dark gray, metallic scorebug was used, located in an unorthodox placement at the center of the bottom of the screen.

text: For the 2008 season, a new graphics scheme was introduced that was built around a new display known as the "dashboard"; the scoreboard, which now took the form of a horizontal bar, was mounted in a dedicated area spanning across the bottom the screen. All lower-third graphics were also displayed within the dashboard, replacing the scorebar when in use.[21]

text: For the 2009 and 2010 seasons, a revamped version of the 2008 design was used, incorporating a new, metallic silver design. Timeout indicators were added to the score bar in Week 4 of the 2009 season. For the 2009 season only, a "40th anniversary" logo was incorporated into the bar in celebration of Monday Night Football's 40th season. The "silver" graphics scheme would later be adopted by other ESPN properties, such as its college football games in December 2009.

text: In the 2011 season, the banner was restructured as a black, metallic design, which was considerably larger than most scorebars – including the previous one (although its sizes has varied, becoming significantly wider, though thinner in 2012). For ESPN's first pre-season game of 2012, the timeout indicators were also accompanied by two smaller red lamps to the right, indicating the number of play challenges remaining, but these were unexpectedly removed the following game. On September 10, 2012, Monday Night Countdown began using MNF's graphics scheme.

text: For the 2015 season, the graphics were completely overhauled to match the motif that has been used for ESPN's NFL studio programming since the year prior. However, the studio programming uses the new motif only for introductions and transitions, while the actual insert graphics use the standard ESPN package used for SportsCenter and all other sports. Meanwhile, MNF uses the NFL motif for all insert graphics, not just introductions and transitions. Most notably, the NFL motif uses a horizontal score bar across the bottom of the screen, whereas the standard graphics package uses a score box. The layout is standard, with teams on the background of their color, with timeout indicators also displaying in team colors. Experimentally, the score bar "auto-hides" itself during plays, though it is shown permanently during the final two minutes of each half and, if necessary, overtime. This is also the first time that ESPN has used the full 16:9 frame for its NFL graphics.

text: Scheduling on local stations[edit]

text: From 1970 to 1997, ABC's Monday Night Football coverage began at 9:00 p.m. Eastern Time, with game kickoff typically occurring at seven minutes past the hour. Coverage was moved one hour earlier to 8:00 p.m. Eastern Time in 1998, with a pre-game show titled Monday Night Blast, hosted by Chris Berman from the ESPN Zone restaurant in Baltimore preceding the start of the game at 8:20 p.m. This was done mainly to address ABC's inability to find a suitable 8:00 p.m. lead-in program for MNF since MacGyver ended its run in 1992 (not even two other series from MacGyver's production company Paramount Television – The Young Indiana Jones Chronicles and The Marshal – saw success, despite the former's ties to Paramount's Indiana Jones film series), and to allow stations to start their late local newscasts nearer to their regular times. Poor ratings caused this experiment to be dropped after one season, with MNF once again moving to 9:00 p.m. in 1999, though in many NFL markets, the 8:00 p.m. (Eastern Time) hour from 1999 to 2006 was replaced by affiliates with locally produced and programmed sports discussion and coaches shows, with ABC programming in that hour moved to late night or weekend slots; by the end of the ABC run, the 8:00 p.m. timeslot was filled with either newsmagazines and short-lived reality television programs which failed to make any ratings headways due to affiliate pre-emptions.

text: From 1970 to 1995, Fisher Broadcasting's ABC affiliates in Seattle (KOMO-TV) and Portland (KATU) aired MNF games on a one-hour tape delay starting at 7:00 p.m. Pacific Time (games normally started in the Pacific Time Zone at 6:00 p.m., corresponding to 9:00 Eastern) in order to accommodate local newscasts (unless the Seattle Seahawks were playing, in which case the game would be shown live). The practice, long opposed by viewers and ABC, ended in 1996. KOMO then tried to accommodate having to air its local newscasts earlier than its local station competitors by marketing it as KOMO 4 News Primetime, touting it as a way to watch the news at a more convenient time than during evening rush hour. Additionally, this practice was done in Hawaii, where Honolulu ABC affiliate KITV delayed the game until 6:00 p.m. Hawaii-Aleutian Time, corresponding to 11:00 p.m. or midnight Eastern during daylight saving time on the mainland. Thus, the game, which was broadcast live on local radio starting at 3:00 or 4:00 p.m., was almost over before it aired on television. In the case of Guam, KTGM, the ABC affiliate in that U.S. territory, aired MNF live on Tuesdays at 11:00 a.m., as Guam is a day ahead of the United States due to being located on the other side of International Date Line.

text: The demand to broadcast Monday Night Football games live across the United States over ABC was difficult to reconcile with other prime time programming, which is usually set to begin at a certain local time regardless of time zone. On the East Coast, with MNF beginning at 9:00 p.m. Eastern Time, there was an hour of primetime in which to schedule regular programming. However, on the West Coast, the games lasted from 6:00 to 9:30 p.m. Pacific Time (or in the case of Seattle and Portland from 1970 to 1995, 7:00 to 10:30 p.m.), leaving little or no time for additional network programming on Monday. As a result, network programs scheduled for prime time on the East Coast were broadcast at various hours on the West Coast. Most affiliates pushed the network shows to immediately after the game; however, Los Angeles owned-and-operated station KABC-TV postponed them until 10:00 p.m. from at least the mid-1990s until 2005 to show trivia contests and other sports shows produced locally (the longest-tenured such show was Monday Night Live, hosted by sports anchor Todd Donoho). Meanwhile, KOMO, one of the stations that tape-delayed MNF in most cases, broadcast new episodes of the sitcom Coach on Saturday afternoons (usually reserved, coincidentally enough, for college football telecasts; much of the series took place on a fictional college campus). Except for Seattle and Portland from 1970 to 1995, ABC World News Tonight was routinely preempted on most West Coast affiliates, though the ABC network-owned stations (e.g. Los Angeles) aired the program earlier in the afternoon.

text: Since ESPN took over the coverage in 2006, games normally have a kickoff time of 8:30 p.m. Eastern. However, when ESPN airs a doubleheader during the first week of the season, the games respectively start at 7:00 and 10:15 p.m. Eastern. There have been issues with local stations in the ESPN era, where stations in each team's home market that air the ESPN simulcast are in most cases ABC affiliates, which must pre-empt Dancing with the Stars to air NFL. This both forces the affiliate to air that program immediately after late-evening local newscasts, and has resulted in the program's telephone and Internet voting coordinators keeping a late-night voting window open for the market or markets where Dancing with the Stars was pre-empted.

text: In some cases, the program is moved to a sister station of the ABC affiliate to air live instead (for example, until 2011 in the Minneapolis–St. Paul market, when NBC affiliate KARE took over as the local broadcaster of MNF games, if the Minnesota Vikings were playing a game being simulcast on local ABC affiliate KSTP-TV, sister independent station KSTC-TV aired DWTS live). In 2016, for the opening week Monday night game (the second in a doubleheader) between the Los Angeles Rams and San Francisco 49ers, the ABC-owned stations in both markets (KABC-TV and KGO-TV) would broadcast World News Tonight and DWTS in their live Eastern Time Zone slots, thus airing at 3:30 and 5pm PT respectively.

text: Commentators[edit]

text: Foreign-language versions[edit]

text: Spanish version[edit]

text: Since 2006, a Spanish-language telecast is also broadcast on ESPN Deportes, the Spanish version of ESPN and on ESPN Latin América featuring NBA and NFL play-by-play announcer Álvaro Martín, Super Bowl winner Raul Allegre as color commentator and John Sutcliffe as the field reporter. This is the same crew of La NFL Dominical, the Spanish version of ESPN Sunday Night Football, until 2005. The announcers of the second game of the 2006 doubleheader were Eduardo Varela (play-by-play), Robert Abramowitz (color) and Georgina Ruiz Sandoval (field reporter). Preceding the game NFL Esta Noche (NFL Tonight), the 30-minute pre-game show, can be seen on both networks.

text: The four booth announcers called the 2007 season opening games from ESPN's Bristol, Connecticut headquarters while watching games on monitors. None of them traveled to the game sites and there were no sideline reporters in the early weeks. Sutcliffe would later report from the game sites. Allegre did not work the season finale between the Broncos and Chargers; he was replaced by Abramovitz.

text: In 2008, Martin and Allegre only travelled to the Cowboys-Eagles game, during the NFL's celebrations of the Hispanic Heritage Month.

text: As part of ESPN's agreement to simulcast their Wild Card game on ABC, Martin and Allegre's Spanish-language commentary is carried over the SAP channel on ABC, equivalent to the rest of the NFL's over-the-air broadcast partners.

text: In 2016, ESPN Deportes served as the official Spanish-language broadcaster of Super Bowl 50 in parallel with CBS's English-language broadcast, with Martin and Allegre commentating.[22][23][24][25]

text: During the first 9 weeks of the 2017 NFL season, ESPN2 will simulcast ESPN Deportes' broadcast, NFL Esta Noche, and the Spanish version of SportsCenter.[26]

text: Portuguese version[edit]

text: Since the 1990s, ESPN Latin America has a feed in Portuguese language targeted to their viewers in Brazil. Ivan Zimmermann (play-by-play), André José Adler (play-by-play), Roberto Figueroa (color), Marco Alfaro (color) among others, were the announcers broadcasting from ESPN's headquarters. Since 2006, the structure of the Brazilian feed was merged with ESPN Brasil and the broadcasting is made from São Paulo. The current announcers are Everaldo Marques (play-by-play) and Paulo Antunes (color). Ari Aguiar (play-by-play), Rômulo Mendonça (play-by-play), Paulo Mancha (color) and Antony Curti (color) occasionally fill-in.

text: Radio broadcasts[edit]

text: Monday Night Football has also been carried on national radio networks over the years. The Mutual Broadcasting System aired the games initially, with Van Patrick (1972–1973), Lindsey Nelson (1974–1977) and Al Wester announcing. CBS Radio took over the rights in 1978 with Jack Buck and Hank Stram commentating. After a two-year stint (1985–1986) with Don Criqui and Bob Trumpy calling the games on NBC Radio, Buck and Stram resumed with CBS Radio in 1987. In 1996, Howard David and Matt Millen replaced Buck and Stram. Marv Albert and Boomer Esiason were the MNF radio voices from 2002 to 2009, with Kevin Harlan replacing Albert in 2010. Kurt Warner joined the crew in 2014 for games when Esiason is unavailable.

text: In the 1990s, CBS Radio purchased a controlling stake in Westwood One, which in turn had bought out both the NBC and Mutual networks. As of 2008, Westwood One was no longer controlled by CBS, but the network retained its NFL broadcast rights. In 2011, Westwood One was purchased by Dial Global. Then in 2014, Dial Global, including Westwood One, was acquired by Cumulus Media.

text: The Spanish-language broadcast is carried on ESPN Deportes Radio.

text: Nielsen ratings[edit]

text: This article needs to be updated. Please update this article to reflect recent events or newly available information. (December 2016)

text: The highest-rated Monday Night Football telecast on ABC was the Miami Dolphins' victory over the previously undefeated Chicago Bears on December 2, 1985, which drew a national Nielsen rating of 29.6 and a share of 46. ABC's lowest-rated MNF game was the St. Louis Rams' defeat of the Tampa Bay Buccaneers on October 18, 2004, which drew a 7.7 rating.

text: During the 1995–1996 television season, Monday Night Football averaged a 17.1 household rating. Its main competitor, Murphy Brown on CBS, averaged a 12.3 rating.[27]

text: The highest-rated Monday Night Football game on ESPN, and the highest-rated program in U.S. cable television history at that time, was the Minnesota Vikings' defeat of the Green Bay Packers 30–23 on October 5, 2009, with a rating of 15.3. The game featured the much-hyped matchup of Vikings quarterback Brett Favre facing his longtime former Green Bay team. In a press release, ESPN noted that the telecast "was watched by more than 16.8 million people. The previous record was more than 13.6 million viewers for 2008's Monday night game between the Philadelphia Eagles and Dallas Cowboys. This was subsequently beaten by ESPN's coverage of the 2011 BCS National Championship Game. ESPN also stated that the game drew the highest rating in the network's 30-year history. The 15.3 rating beat the 14.4 for a Bears-Vikings game on Dec. 6, 1987, during ESPN's first season of televising NFL games".[28] ESPN's lowest-rated MNF game to date was the New York Giants' defeat of the Atlanta Falcons on October 15, 2007, which drew a 5.7 rating.

text: ESPN's third season of Monday Night Football was the most-watched program on cable television in 2008, setting an all-time cable viewership record for the third straight year and drawing that year's three largest cable household audiences and 13 of the top 15. In three seasons on ESPN, Monday Night Football has registered seven of the top 10 all-time largest household audiences in cable history, led by the Eagles-Cowboys telecast on September 15, 2008, which attracted cable's largest household audience ever (an average of 12,953,000 homes). ESPN's 17 MNF telecasts in 2008 averaged an 8.9 rating, representing an average of 8,679,000 households (11,962,000 viewers), increases of 3%, 5% and 7%, respectively, vs. 2007 (8.6; 8,277,000 and 11,230,000).[29]

text: Additional NFL game rights[edit]

text: Playoff games[edit]

text: When ABC first acquired the rights to air MNF in 1970, it did not include any playoff games. The network was eventually allowed into the rotation of airing the Super Bowl, starting with Super Bowl XIX in January 1985. When the league expanded the playoffs from a 10-team to a 12-team tournament in 1990, ABC was then given the rights to air the first two Wild Card Playoff games.

text: After MNF was awarded to ESPN and Sunday Night Football was acquired by NBC in 2006, the Wild Card doubleheader that had aired on ABC, as well as a share of the rotating rights to the Super Bowl, was also given to NBC.

text: On April 22, 2014, the NFL announced that it had exercised an option in ESPN's recent contract extension for Monday Night Football rights to air a first-round Wild Card playoff game on the channel after the conclusion of the 2014 season. This was the first time that an NFL playoff game was ever broadcast exclusively on cable television in the United States, in lieu of any of the league's broadcast network partners.[30][31][32] The MNF broadcast team of Mike Tirico, Jon Gruden and sideline reporter Lisa Salters called the game, the first of the 2014–15 NFL playoffs. The Carolina Panthers defeated the Arizona Cardinals 27–16.[30][31] As with all MNF games, the matchup was simulcast on WJZY in Charlotte and KASW in the Phoenix market to allow local viewers over-the-air access to the game.

text: However, the cable-only playoff game experiment would only last one season. On May 11, 2015, it was announced that ABC would simulcast a Wild Card playoff game with ESPN for the 2015 season.[33] This was the first NFL game broadcast nationally on ABC since MNF left the network at the end of the 2005 season. The game, announced by the broadcast team of Tirico, Gruden and Salters, was the first of the 2015–16 NFL playoffs. The Kansas City Chiefs defeated the Houston Texans 30–0. The ESPN/ABC simulcast continued for the 2016 season as well.[34][35]

text: Pro Bowl[edit]

text: ABC televised the Pro Bowl from 1975 to 1987, and again from 1995 to 2003.

text: As part of their 2011 rights agreement, ESPN was given the exclusive rights to the Pro Bowl from 2015 through 2022.[30] Starting in 2018, it will be simulcast on ABC.


document_title: Radiation implosion

question_text: who designed the staged radiation implosion model of the hydrogen bomb

text: Radiation implosion

text: History[edit]

text: Radiation implosion was first developed by Klaus Fuchs and John von Neumann in the United States, as part of their work on the original "Classical Super" hydrogen bomb design. Their work resulted in a secret patent filed in 1946, and later given to the USSR by Fuchs as part of his nuclear espionage. However, their scheme was not the same as used in the final hydrogen bomb design, and neither the American nor the Soviet programs were able to make use of it directly in developing the hydrogen bomb (its value would become apparent only after the fact). A modified version of the Fuchs-von Neumann scheme was incorporated into the "George" shot of Operation Greenhouse.[1]

text: In 1951, Stanislaw Ulam had the idea to use hydrodynamic shock of a fission weapon to compress more fissionable material to incredible densities in order to make megaton-range, two-stage fission bombs. He then realized that this approach might be useful for starting a thermonuclear reaction. He presented the idea to Edward Teller, who realized that radiation compression would be both faster and more efficient than mechanical shock. This combination of ideas, along with a fission "sparkplug" embedded inside of the fusion fuel, became what is known as the Teller–Ulam design for the hydrogen bomb.

text: Fission bomb radiation source[edit]

text: Most of the energy released by a fission bomb is in the form of x-rays. The spectrum is approximately that of a black body at a temperature of 50,000,000 kelvins (a little more than three times the temperature of the Sun's core). The amplitude can be modeled as a trapezoidal pulse with a one microsecond rise time, one microsecond plateau, and one microsecond fall time. For a 30 kiloton fission bomb, the total x-ray output would be 100 terajoules.

text: Radiation transport[edit]

text: In a Teller-Ulam bomb, the object to be imploded is called the "secondary". It contains fusion material, such as lithium deuteride, and its outer layers are a material which is opaque to x-rays, such as lead or uranium-238.

text: In order to get the x-rays from the surface of the primary, the fission bomb, to the surface of the secondary, a system of "x-ray reflectors" is used.

text: The reflector is typically a cylinder made of a material such as uranium. The primary is located at one end of the cylinder and the secondary is located at the other end. The interior of the cylinder is commonly filled with a foam which is mostly transparent to x-rays, such as polystyrene.

text: The term reflector is misleading, since it gives the reader an idea that the device works like a mirror. Some of the x-rays are diffused or scattered, but the majority of the energy transport happens by a two-step process: the x-ray reflector is heated to a high temperature by the flux from the primary, and then it emits x-rays which travel to the secondary. Various classified methods are used to improve the performance of the reflection process[citation needed].

text: Some Chinese documents show that Chinese scientists used a different method to achieve radiation implosion. According to these documents, an X-ray lens, not a reflector, was used to transfer the energy from primary to secondary during the making of the first Chinese H-bomb.[2]

text: The implosion process in nuclear weapons[edit]

text: The term "radiation implosion" suggests that the secondary is crushed by radiation pressure, and calculations show that while this pressure is very large, the pressure of the materials vaporized by the radiation is much larger. The outer layers of the secondary become so hot that they vaporize and fly off the surface at high speeds. The recoil from this surface layer ejection produces pressures which are an order of magnitude stronger than the simple radiation pressure. The so-called radiation implosion in thermonuclear weapons is therefore thought to be a radiation-powered ablation-drive implosion.

text: Laser radiation implosions[edit]

text: There has been much interest in the use of large lasers to ignite small amounts of fusion material. This process is known as inertial confinement fusion (ICF). As part of that research, much information on radiation implosion technology has been declassified.

text: When using optical lasers, there is a distinction made between "direct drive" and "indirect drive" systems. In a direct drive system, the laser beam(s) are directed onto the target, and the rise time of the laser system determines what kind of compression profile will be achieved.

text: In an indirect drive system, the target is surrounded by a shell (called a Hohlraum) of some intermediate-Z material, such as selenium. The laser heats this shell to a temperature such that it emits x-rays, and these x-rays are then transported onto the fusion target. Indirect drive has various advantages, including better control over the spectrum of the radiation, smaller system size (the secondary radiation typically has a wavelength 100 times smaller than the driver laser), and more precise control over the compression profile.

text: 1898 St. Louis Browns and 1899 Cleveland Spiders[edit]

text: The 1899 Cleveland Spiders own the worst single-season record of all time (minimum 120 games) and for all eras, finishing at 20–134 (.130 percentage) in the final year of the National League's 12-team era in the 1890s; for comparison, this projects to 21–141 under the current 162-game schedule, and Pythagorean expectation based on the Spiders' results and the current 162-game schedule predicts a record of 25–137.

text: The Spiders had a fair amount of success in the 1890s, with seven straight winning seasons from 1892 to 1898 and a Temple Cup victory in 1895. Meanwhile, the once four-time American Association champion St. Louis Browns had fallen to 29–102 in 1897 and to 39–111 (including 19–67 on the road) in 1898. But the Spiders ownership, the Robison brothers, bought the Browns in time for the 1899 season, creating a conflict-of-interest situation which was later outlawed. On the eve of the season, they traded almost all of Cleveland's good players to St. Louis for very little in return, with respectable results for St. Louis and disastrous results for Cleveland.

text: The 1899 Spiders set the major league record for most consecutive losses in a season (24, from July 26 to September 16), and had six losing streaks of 10 games or more. The Spiders lost 40 of their last 41 games, finishing 84 games behind the 1899 National League champion Brooklyn Dodgers and 35 games behind the second-last-placed Washington Senators. They lost 27 games in September, a record for the most games lost in a month until the 1909 Washington Senators went 5–29 in July. Due to paltry attendances, the Spiders played 112 games on the road, finishing with a road record of 11–101 (the 101 road losses is a record which is unbreakable under the current MLB scheduling rules, which allow a maximum of 81 road games).

text: The 1899 Browns, renamed the "Perfectos" and staffed with all the best players from the 1898 Spiders (six of the Spiders' eight starting position players and four starting pitchers, including the great Cy Young) improved by 44½ games, from 39–111 to 84–67. However, all St. Louis did ultimately was to trade places with Cleveland in the standings. The Browns/Perfectos were renamed the St. Louis Cardinals in 1900, and are unrelated to the American League St. Louis Browns that adopted the discarded nickname and also appear on this list.

text: After the 1899 season, the National League contracted from twelve to eight clubs for the 1900 season, with the Spiders, the original Baltimore Orioles, Louisville Colonels (Louisville has never had another major league team since), and the original Washington Senators folding operations. Baltimore had also been stripped of its best players by Brooklyn in 1899, to somewhat less dramatic effect, but still enough to speed their demise. The smaller 1900 National League allowed the Western League to fulfill its dreams of becoming a major league, filling the void in a number of cities by renaming itself the American League in 1900 and declaring itself a major league in 1901.

text: Other teams[edit]

text: With shorter schedules before 1886, it was much more common for teams to finish with sub-.300 winning percentages, as there was less of the evening out effect of a longer season.

text: Four teams have finished with worse overall winning percentages than the 1899 Spiders, but these teams played less than 50 games during their seasons, and in leagues whose status as "major" is questionable.

text: Three of these occurred in the National Association (the status of the National Association as a major league has long been disputed):

text:
The 1872 Brooklyn Eckfords finished at 3-26 (.103 percentage), which for comparison would project to 17–145 under the current schedule, and Pythagorean expectation based on the Eckfords' results and the current 162-game schedule predicts a record of 19–143.
The 1873 Elizabeth Resolutes finished at 2–21 (.087 percentage), which for comparison would project to 14–148 under the current schedule, and Pythagorean expectation based on the Resolutes' results and the current 162-game schedule predicts a record of 16–146.
The 1875 Brooklyn Atlantics finished at 2–42 (.045 percentage), which for comparison would project to 7–155 under the current schedule, and Pythagorean expectation based on the Atlantics' results and the current 162-game schedule predicts a record of 13–149.

text: The Wilmington Quicksteps of the 1884 Union Association played only 18 games, finishing with a 2–16 record (.111 percentage) before they dropped out of the Association and folded. For comparison, this projects to 18–144 under the current schedule, and Pythagorean expectation based on the Quicksteps' results and the current 162-game schedule predicts a record of 14–148. However, while the Union Association is conventionally listed as a major league, this status has been questioned due to the league's overall lack of playing talent and poor organizational structure.

text: Contemporary baseball guides did not consider the Union Association to be a major league, with the earliest record referencing the Union Association as a major league dating to 1922.[1]

text: The 1890 Alleghenys were gutted before the season when nearly all of their best players defected to the Pittsburgh Burghers of the Players' League. Poor attendances meant that they played 97 of their 136 games on the road, finishing with a road record of 9–88 (the 88 road losses remained a record until 1899, and is unreachable under current MLB scheduling rules). The Alleghenys .093 road winning percentage is the lowest in MLB history for a minimum of 60 games.

text: The Philadelphia Athletics were a good team in the early 1910s, winning American League pennants in 1913 and 1914 and the World Series in 1913. However, owner-manager Connie Mack felt that he was unable to pay his star players' salaries while the Federal League was in operation, and he sold or traded most of them after the 1914 World Series ended. The Athletics then finished in last place from 1915–1922. In 1916, they went 36–117, including 13–64 on the road. The 1916 Athletics .235 winning percentage is the sixth-lowest of any MLB team and the lowest since 1900.

text: The 1935 Boston Braves featured Hall of Famers Rabbit Maranville (age 43) and Babe Ruth (age 40). Braves owner Emil Fuchs had promised Ruth an ownership stake in the Braves and a chance to manage the club in the near future, but had little intention of delivering either. Ruth retired on June 1, 1935, having hit .181 in 72 at-bats for the Braves, with six home runs (the last three all coming on the same day, May 25, 1935, at Pittsburgh).  Fuchs, who had been plagued by financial problems for a decade, was forced to give up control of the Braves before the end of the season. The Braves' home winning percentage of .167 is the fifth-lowest of any MLB team and the lowest since 1900.

text: The 1939 Browns drew 386 fans to the park for a 7–4 home loss to Detroit on September 27.[2]

text: The 1962 New York Mets were an expansion team created to fill the void after  the New York Giants and Brooklyn Dodgers left New York City at end of the 1957 season. The Mets, filled with castoffs like "Marvelous" Marv Throneberry as well as aging Hall of Famer Richie Ashburn and low-talent rookies such as Choo-Choo Coleman, finished with the third-worst winning percentage in the modern era and the modern-era record for most losses. The Mets went on to finish last or next-to-last for seven years in a row, before they shocked the baseball world by winning the 1969 World Series.

text: The 2003 Tigers seemed like a sure bet to break the 1962 Mets' modern record for most losses when they stood at 38–118 after 156 games, but they won five of their last six to avoid ignominy. On September 27, in their penultimate game, the Tigers came back from an 8–0 deficit to beat the Minnesota Twins 9–8 (the Twins, having just clinched the division, were resting their starters).[3] When the Tigers won the season finale to avoid tying the record, they received a standing ovation from the crowd. Mike Maroth, a starting pitcher for the 2003 Detroit Tigers, went 9–21 and became the first pitcher to lose 20 games in a season since Brian Kingman dropped 20 games for the 1980 Oakland Athletics.[4] Ramón Santiago of the Tigers became only the 12th Triple Crown loser (a player who finishes last in all of the three Triple Crown categories) in modern MLB history.[5]  One baseball statistician described the Tigers as possibly "the worst team of all time without a good excuse", as virtually every other team on the list had been reduced to minor-league status, plagued by financial problems or was a first-year expansion team.[6]

text: Three years after losing 119 games, the Detroit Tigers went 95–67 and won their 10th American League pennant, before losing the World Series to the St. Louis Cardinals. Players common to the 2003 and 2006 Tigers teams included Brandon Inge, Ramón Santiago (who spent 2004 and 2005 with the Seattle Mariners), Craig Monroe, Dmitri Young (released in September 2006), Omar Infante, Mike Maroth, Jeremy Bonderman, Nate Robertson, Jamie Walker, Wilfredo Ledezma, and Fernando Rodney.
