21 September 2026 marks 56 years since the first Monday Night Football broadcast. On 21 September 1970 ABC carried the NFL game between the Cleveland Browns and the New York Jets from Cleveland Municipal Stadium in prime time.

The Browns won 31–21. The match opened the 1970 season for both clubs and moved American football into a high-audience Monday slot, not only the league’s usual weekend window.

Producer Roone Arledge changed the presentation: more cameras than a standard telecast, replays and a three-person booth. Keith Jackson handled play-by-play alongside Howard Cosell and Don Meredith.

Among the scoring plays, box-score archives record Homer Jones’s 94-yard kickoff return and, late on, Billy Andrews’s 25-yard interception return that closed the score. Joe Namath played for the Jets. Statistics from this game are kept separate from the programme’s later overall records.

Contemporary reports noted a crowd of more than 80,000; Associated Press cited a club-record 85,763. National audience figures vary by methodology and are not restated here as a single total.

The programme became a landmark of American sports television. Its network, commentators, graphics and technology changed; Monday night’s game remained a fixture in the NFL calendar. Logos, archive video and league visual identity are protected and are not reproduced here.

The 56-year marker refers to the 1970 debut, not to a current-season match, and invents no unconfirmed studio guests or on-air moments.
