During the early 1960s, NFL Commissioner Pete Rozelle envisioned the possibility of playing at least one game weekly during prime time that could be viewed by a greater television audience (while the NFL had scheduled Saturday night games on the DuMont Television Network in 1953 and 1954, poor ratings and the dissolution of DuMont led to those games being eliminated by the time CBS took over the rights in 1956). An early bid by the league in 1964 to play on Friday nights was soundly defeated, with critics charging that such telecasts would damage the attendance at high school football games. Undaunted, Rozelle decided to experiment with the concept of playing on Monday night, scheduling the Green Bay Packers and Detroit Lions for a game on September 28, 1964. While the game was not televised, it drew a sellout crowd of 59,203 spectators to Tiger Stadium, the largest crowd ever to watch a professional football game in Detroit up to that point.

Two years later, Rozelle would build on this success as the NFL began a four-year experiment of playing on Monday night, scheduling one game in prime time on CBS during the 1966 and 1967 seasons, and two contests during each of the next two years. NBC followed suit in 1968 and 1969 with games involving American Football League teams.

During subsequent negotiations on a new television contract that would begin in 1970 (coinciding with a merger between the NFL and AFL), Rozelle concentrated on signing a weekly Monday night deal with one of the three major networks. After sensing reluctance from both NBC and CBS in disturbing their regular programming schedules, Rozelle spoke with ABC.

Despite the network's status at the time as the lowest-rated of the three major broadcast networks, ABC was also reluctant to enter the risky venture. It was only after Rozelle used the threat of signing a deal with the independent Hughes Sports Network, an entity bankrolled by reclusive businessman Howard Hughes, did ABC sign a contract for the scheduled games. Speculation was that had Rozelle signed with Hughes, many ABC affiliates would have pre-empted the network's Monday lineup in favor of the games, severely damaging potential ratings.

After the final contract for Monday Night Football was signed, ABC Sports producer Roone Arledge immediately saw possibilities for the new program. Setting out to create an entertainment "spectacle" as much as a simple sports broadcast, Arledge hired Chet Forte, who would serve as director of the program for over 22 years. Arledge also ordered twice the usual number of cameras to cover the game, expanded the regular two-man broadcasting booth to three, and used extensive graphic design within the show as well as instant replay.

Year-by-year breakdown 1970 Super Bowl IV was broadcast in the United States by CBS with play-by-play announcer Jack Buck and color commentator Pat Summerall, with Frank Gifford and Jack Whitaker reporting from the winning and losing locker rooms, respectively. While the game was sold out at Tulane Stadium, the NFL's unconditional blackout rules in place then prohibited the live telecast from being shown in the New Orleans area.

CBS erased the videotape a few days after the game; the same thing it did with Super Bowls I and II, which it broadcast. Videotape was expensive then and networks did not believe old games were worth saving. The only reason video of this game exists is because the CBC in Canada and Radio-Canada in Québec carried the broadcast due to the Vikings' popularity in the country as a whole and the French-speaking province. Additionally, Minnesota's head coach, Bud Grant, was a legendary player and coach in the Canadian Football League. The CBC decided to save it for its archives, transferring the footage to black & white film (kinescope). This, therefore, enabled the CBC to reuse the videotape but also keep a record of the game broadcast, which can be seen on YouTube.

In 1970, after the NFL and AFL completed their merger, NBC signed a contract with the league to broadcast games from the American Football Conference (AFC). Curt Gowdy, who had covered the first five seasons of the American Football League with broadcast partner Paul Christman on ABC, moved over to NBC in the fall of 1965. For the next decade, Gowdy was the lead play-by-play announcer for the network for both AFL football (AFC from 1970 onward) and Major League Baseball games; however, Gowdy also covered a wide range of sports, earning him the nickname of the "broadcaster of everything." Besides Paul Christman, Curt Gowdy's other football broadcast partners were Kyle Rote, Al DeRogatis, Don Meredith, John Brodie and Merlin Olsen.

Looking for a lightning rod to garner attention, Arledge hired controversial New York City sportscaster Howard Cosell as a commentator, along with veteran football play-by-play announcer Keith Jackson. Arledge had tried to lure Curt Gowdy and then Vin Scully to ABC for the MNF play-by-play role, but settled for Jackson after they proved unable to break their respective existing contracts with NBC Sports and the Los Angeles Dodgers. Jack Buck was also considered, but when Arledge assistant Chuck Howard telephoned Buck with the job offer, Buck refused to respond due to anger at his treatment by ABC during an earlier stint with the network. Arledge's original choice for the third member of the trio, Frank Gifford, was unavailable since he was still under contract to CBS Sports. However, Gifford suggested former Dallas Cowboys quarterback Don Meredith, setting the stage for years of fireworks between the often-pompous Cosell and the laid-back Meredith and sometimes, the good-looking Gifford.

On September 20, 1970, The NFL Today signed industry-pioneering women: Marjorie Margolies (who years later won election to the U.S. House from Pennsylvania in 1992 as Marjorie Margolies-Mezsvinsky), who produced and reported features and actress Carole Howey, who also reported for the program.

Monday Night Football first aired on ABC on September 21, 1970, with a game between the New York Jets and the Browns in Cleveland. Advertisers were charged US$65,000 per minute by ABC during the clash, a cost that proved to be a bargain when the contest collected 33% of the viewing audience. The Browns defeated the Jets, 31-21 in a game which featured a 94-yard kickoff return for a touchdown by the Browns' Homer Jones and was punctuated when Billy Andrews intercepted Joe Namath late in the fourth quarter and returned it 25 yards for the clinching touchdown. However, Cleveland viewers saw different programming on WEWS-TV, because of the NFL's blackout rules of the time (this would apply for all games through the end of the 1972 season; beginning in 1973, home games could be televised if tickets were sold out 72 hours before kickoff).

1971 On January 17, 1971, NBC's telecast of Super Bowl V between the Baltimore Colts and Dallas Cowboys was viewed in an estimated 23,980,000 homes, the largest household audience ever for a one-day sports event. The game was called by play-by-play announcer Curt Gowdy and color commentator Kyle Rote. Although the Orange Bowl was sold out for the event, unconditional blackout rules in the NFL prohibited the live telecast from being shown in the Miami area on WSVN. The blackout was challenged in Miami-Dade District Court by attorney Ellis Rubin, and although the judge denied Rubin's request since he felt he did not have the power to overrule the NFL, he agreed with Rubin's argument that the blackout rule was unnecessary for the Super Bowl.

The game was also the first Super Bowl to be carried live in the state of Alaska; thanks to NBC's then-parent company RCA acquiring the Alaska Communications System from the United States Air Force. The complete original broadcast, up until Chuck Howley's second interception, the first play of the fourth quarter exists, however the rest of the fourth quarter is missing from network vaults. Broadcast excerpts of the crucial fourth-quarter plays, recovered from the Canadian feed of NBC's original, do exist and circulate among collectors. (Two different NFL Films game compilations also cover the fourth quarter plays, in part.)

By 1971, the Federal Communications Commission (FCC) introduced the Prime Time Access Rule, which freed local network affiliates in the top 50 markets (in practice, the entire network) to take a half-hour of prime time from the networks on Mondays through Saturdays and one full hour on Sundays. Because nearly all affiliates found production costs for the FCC's intended goal of increased public affairs programming very high and the ratings (and by association, advertising revenues) low, making it mostly unprofitable, the FCC created an exception for network-authored news and public affairs. After a six-month hiatus in late 1971, CBS would find a prime place for 60 Minutes in a portion of that displaced time, 6:00 to 7:00 p.m. (Eastern; 5:00 to 6:00 Central Time) on Sundays, in January 1972.Madsen 15 This proved somewhat less than satisfactory, however, because in order to accommodate CBS' telecasts of late afternoon National Football League games, 60 Minutes went on hiatus during the fall from 1972 to 1975 (and the summer of 1972). This took place because football telecasts were protected contractually from interruptions in the wake of the infamous "Heidi Game" incident on NBC in November 1968.

Due largely to CBS' live broadcast of NFL games, as well as other sports events aired by the network that run past their scheduled end time, 60 Minutes sometimes does not start until after 7:00 p.m. Eastern Time, with the program starting right after the conclusion of game coverage (however, on the West Coast, because the actual end of the live games is much earlier in the afternoon in comparison to the Eastern and Central Time Zones, 60 Minutes is always able to start at its normal 7:00 p.m. Pacific start time, leaving affiliates free to broadcast local newscasts, the CBS Evening News, and other local or syndicated programming leading up to 60 Minutes). The program's success has also led CBS Sports to schedule events leading into 60 Minutes and the rest of the network's primetime lineup, causing (again, except on the West Coast) the pre-emptions of the Sunday editions of the CBS Evening News and affiliates' local newscasts.

In 1971, Frank Gifford became available after his contract with CBS Sports concluded; Arledge brought him to ABC to serve as play-by-play announcer, replacing Jackson (who returned to broadcasting college football for the network, which he continued to do for the next 35 seasons). The former New York Giant had been an NFL analyst for CBS during the 1960s but had never called play-by-play prior to joining Monday Night Football. In that capacity for Monday Night Football from 1971 to 1985, Gifford was often criticized for his see-no-evil approach in regard to discussing the NFL, earning him the dubious nickname "Faultless Frank." Regardless, Gifford would have the longest tenure of any broadcaster on the show, lasting until 1998.

Jack Whitaker and Pat Summerall took over hosting duties on The NFL Today from Gifford.

Howard Cosell's abrasive personality gave him enough recognition to host a live variety show on ABC in the fall of 1975. That show is remembered today only as a trivia question, as its title, Saturday Night Live, prevented a new late-night sketch comedy program on NBC from using that title until the ABC show was canceled. That seeming popularity was in contrast to the repeated criticisms in the media, as well as bar room contests in which winners were allowed to throw a brick through a television image of Cosell.
