''Monday Night Football'' is a [[LongRunner long-running]] weekly broadcast of UsefulNotes/NationalFootballLeague games. Debuting in 1970 on Creator/{{ABC}}, the program was conceived as both an answer to Major League Baseball's ''Game of the Week'' (and the NHL's ''HockeyNightInCanada'') and a showcase for the best teams in the NFL, as the league traditionally uses the coveted ''Monday Night'' slot to spotlight matches between high caliber teams.

There were some Monday night games on Creator/{{CBS}} in the late 1960s as a sort of test run of the concept, but they were not played every week. Those games are not considered part of the series as such.

''Monday Night Football'' was an instant hit in the ratings and quickly became a fixture in American pop culture. In particular, it made household names out of it's announcing team: Play-by-play man Frank Gifford and color analysts Howard Cosell and "Dandy" Don Meredith. It also can be credited for helping make the NFL the most popular sport in the US, as the series routinely highlighted the league's top players and rivalries. It also spun off a spin-off of sorts, as {{ESPN}} (by then majority-owned by ABC) followed suit to launch ''Sunday Night Football'' in 1987.

Sadly, things changed when in 2005 when [[WaltDisney Disney]] (who by that time owned both ABC and ESPN) decided that declining ratings (exacerbated by the popularity of pro wrestling's ''{{WCW}} Monday Nitro'' and ''[[Wrestling/{{WWE}} WWF]] [[WWERaw Monday Night Raw]]'') and escalating TV contracts no longer made the series profitable enough for ABC to keep. A large part of the problem was that competitive balance had become a problem for the schedule makers as the top teams from the previous season might no longer be so the next season. This resulted in late-season match-ups that were clunkers because one or the other of the teams were no longer a playoff contender, making the Monday night game less appealing to a mass audience. ABC also ended up with a [[FridayNightDeathSlot death slot]] before the game after ''MacGyver'' was canceled as no show could recapture the perfect chemistry of Richard Dean Anderson's iconic character leading into ''MNF'', and as many local affiliates figured that out and pre-empted whatever was before the game with a local football show, was stuck airing ''20/20 Downtown'' to complete viewer apathy.

ABC, among other entities, tried to get the NFL to agree to a concept that would eventually become known as "flex scheduling," which would be invoked when needed to replace a poor match-up with a better one. The idea was deemed impractical because of the logistics involved in moving a Sunday afternoon game to Monday night.

As part of that year's reshuffling of the NFL TV contracts, Disney decided to bid on the MNF contract but put the games on ESPN. With subscription fees in addition to regular adversiting income, ESPN could bid more for the contract than ABC and still maintain profitability. The move of the top rated, icon show to cable angered many fans but NBC bid on the now-vacant Sunday night package. The Sunday night game was now considered the marquee game of the week and flex scheduling was put into place for this package as it's much easier to move a game 3 1/2 to 6 1/2 hours later in the day than a day-and-a-half later. Likewise, ''MNF'' ended up taking the games that were on the old Sunday night contract. Disney decided not to bid on the Sunday night package due to the then-dominance of ''DesperateHousewives'' on Sunday nights at the time; while NBC easily wins Sunday evenings, the ABC lineup of ''Series/OnceUponATime'' and ''{{Revenge}}'' has continued to do well as good counterprogramming. ABC's Monday evening lineup of ''DancingWithTheStars'' and ''Series/{{Castle}}'' has done better with a steady lineup through the year, even against ''MNF'', while NBC is now stuck with a post-Super Bowl lineup on Sunday nights which generally trails the other networks.

''Monday Night Football'' remains popular even with the jump to cable and routinely ends up in the Top Ten Nielsen ratings chart every Monday. And with the games on cable, it's now possible to have a season-opening Monday night doubleheader with one game beginning at 7 p.m. Eastern time and the second at 10:15 Eastern. The later game usually involves two west-coast teams (usually the currently awful Raiders have been involved to much viewer and advertiser annoyance), though in 2010, it was played in Kansas City (a 9:15 p.m. kickoff locally). It also gives ESPN a prominent day to market everything about their network, and all programming is focused around both Monday morning quarterbacking and hyping that night's game.

Not to be confused with {{Creator/Sky}} Sports' ''[[TropeCoTropeOfTheWeek Ford]]'' ''Monday Night Football,'' which broadcasts EnglishPremierLeague games.

!!Monday Night Football has been broadcasted on:

* ABC (1970-2005)
* ESPN and [=ESPN2=] (2006-present, as well as a couple of one-off '90s games)

!!Additional Monday night games that are not officially part of the MNF package have been broadcasted on:
* Creator/{{NBC}} (first game of Christmas 2006 doubleheader)
* {{Fox}} (postponed 2010 New York Giants-Minnesota Vikings game, moved to Detroit's Ford Field due to a roof collapse in Minneapolis's Hubert H. Humphrey Metrodome; the game only aired in New York City, Albany, NY, Minneapolis-St. Paul, and Rochester, MN, although it was broadcast nationally to NFL Sunday Ticket subscribers)

!!Monday Night Football contains examples of the following tropes:

* BearerOfBadNews: During a broadcast Howard Cosell broke the news of Music/JohnLennon's death on Dec. 8, 1980. Apparently the booth had been given the bulletin and asked to keep it quiet until ABC News could get on the air. Cosell announced it anyway.
* BootstrappedTheme: Now universally recognized as the ''MNF'' theme music, Johnny Pearson's "[[http://www.youtube.com/watch?v=wIxeOvClzR4 Heavy Action]]" was originally used only as accompaniment for halftime highlights, and didn't become the opening theme until several years later. (The original opening theme was a funky organ-based piece called "[[http://www.youtube.com/watch?v=JV-pYT4wldc Score]]".)
** What's more, "Heavy Action" wasn't actually composed for ''MNF'' at all, but for the {{BBC}} sports-competition show ''Superstars''. (It continues to herald BBC sports broadcasts in the UK.) It also introduced a series of films syndicated by SFM Entertainment under the "SFM Holiday Network" title in the 70s and 80s.
* FlippingTheBird: Done by a disgruntled Houston Oilers fan to the camera during a 1972 game, prompting the classic Meredith quip, "He's saying the Oilers are number one in the nation!"
* GettingCrapPastTheRadar: A few early examples came mainly from Don Meredith:
** During the first Monday Night game between the New York Jets and Cleveland Browns; the camera spotlighted a Cleveland receiver named [[UnfortunateNames Fair Hooker]], prompting Meredith to joke that he "hadn't met one yet".
** During the opening comments from the 1973 game between the Oakland Raiders and Denver Broncos (the latter making their Monday Night debut), Meredith (who occasionally smoked marijuana then) quipped "We're in Mile High, and so am I".
** Then there's this beauty from Dick Vermeil:
-->'''Vermeil''': "There's John Elway on the sidelines getting blown by a fan!" (cue shot of Elway with an electric fan pointed at him)
* HypercompetentSidekick: Hall of Fame QB (and college football commentator) Dan Fouts during Dennis Miller's tenure, who provided meaningful football commentary to back up Miller's non-sequitur quips.
* LongRunner: Over 40 seasons and counting.
* MsFanservice: Some of their female sideline reporters have been seen as this, most notably Melissa Stark and Lisa Guerrero in the latter years of the ABC run.
* MoodWhiplash: The broadcast of Dec. 8, 1980, when Cosell broke the news of Creator/JohnLennon's murder in the middle of the game, noting that in the grand scheme of things, the game wasn't that important.
* OddCouple: Cosell and Meredith openly disliked each other (though they both intentionally played this up), providing dramatic tension in the broadcast and pushing ratings through the roof. Joe Theismann and Tony Kornheiser were a lesser version.
** A one-time historical Odd Couple: one game in 1974 had RonaldReagan and JohnLennon showing up at the same broadcast. Off-screen, Reagan was seen in a friendly chat with Lennon explaining some of the rules of UsefulNotes/AmericanFootball to him.
* RealLifeWritesThePlot: Hurricane Katrina postponed a 2005 game between the New York Giants and New Orleans Saints, moving it from a Sunday afternoon game to Monday night and causing that Monday to have two games. The concept of a Monday night doubleheader in Week 1 was later added into the schedule permanently with the move to ESPN, along with a Christmas doubleheader in 2006 as it fell on a Monday that year.
* SesquipedalianLoquaciousness: Cosell's stock in trade.
* ViewersAreGeniuses: Creator/DennisMiller's run on the show.
** Cosell ocassionally ventured into this territory but knew when to draw back as well. Miller turned it UpToEleven.
