The answer to “when did monday night football start” is September 21, 1970. The Cleveland Browns hosted the New York Jets in the first game of ABC’s new weekly NFL broadcast, winning 31–21.
The debut marked a new way to watch pro football: a nationally televised game in a regular Monday-night slot. Here’s what happened that evening, how the show came together, and why the broadcast became a familiar part of the NFL week. You’ll also find the key dates that explain how Monday Night Football moved from ABC to ESPN.
When did monday night football start?
Monday Night Football began on September 21, 1970, with a game between the Cleveland Browns and New York Jets at Cleveland Municipal Stadium. The Browns won 31–21. ABC aired the matchup as the first broadcast in its new Monday-night NFL series.
The date refers to the start of the regular television program known as Monday Night Football. It does not mean that no NFL game had ever been played on a Monday. The league had scheduled Monday contests before 1970, but the new ABC series gave Monday night a regular place on the national football calendar.
The timing mattered. The 1970 season was the first after the AFL and NFL completed their merger. The new league had more teams and a broader audience to serve, while ABC was looking for a distinctive way to present pro football. A weekly game in a prime-time slot gave viewers a fresh option beyond the weekend schedule.
What happened in the first Monday night game?
The inaugural broadcast featured two high-profile teams. Cleveland was an established NFL club, while New York’s Jets had become a national draw after winning Super Bowl III. The Jets’ quarterback, Joe Namath, was one of the sport’s most recognizable stars. That matchup helped make the first broadcast feel like a major event rather than an ordinary late-season game.
Cleveland took control and won by 10 points. The final score, 31–21, is the simplest answer to what happened on the field. The larger story was that a regular-season NFL game was now being presented in a weekly national prime-time slot, with a broadcast style designed to make the evening itself part of the entertainment.
The game was played at Cleveland Municipal Stadium, the Browns’ home at the time. The stadium’s large crowd and the high-profile opponent gave the debut a strong setting. But the series did not depend on one particular venue or rivalry. Its format brought a different NFL matchup to television each Monday night during the season.
How ABC created a new kind of NFL broadcast
ABC Sports executive Roone Arledge helped shape the program. His team treated the game as both a sporting contest and a television event. The production used a more energetic presentation than viewers might expect from a straightforward play-by-play broadcast, giving the announcers room to explain the action, react to it, and entertain the audience.
The first booth featured play-by-play announcer Keith Jackson alongside commentators Howard Cosell and Don Meredith. Their contrasting voices became a defining feature of the early show. Jackson guided viewers through the action, Cosell brought a forceful and often provocative style, and Meredith added a relaxed, humorous presence.
That mix helped make the broadcast accessible to people who were not devoted fans of either team. Viewers could follow the score and key plays while also enjoying the personalities in the booth. The announcers became part of the weekly attraction, not just voices heard between snaps.
ABC also gave the game a clear identity. The network used opening sequences, music, graphics, and a consistent time slot to make Monday night feel different from a Sunday afternoon game. These choices helped viewers recognize the program before kickoff and gave the broadcast a sense of occasion.
Why the Monday-night schedule caught on
A regular Monday game gave football fans another predictable appointment. Instead of waiting for the weekend, viewers could follow an NFL matchup at the start of the workweek. The schedule also made the game easy to discuss at work, school, and around the water cooler the next day.
The format worked for television because a single featured game concentrated attention. On a typical Sunday, many NFL games compete for viewers across different channels and time slots. A Monday-night broadcast put the spotlight on one matchup for a national audience, making it easier for fans in different cities to share the same game.
The broadcast also benefited from the NFL’s growing popularity and the appeal of recognizable teams and players. A strong matchup helped draw viewers, while the show’s lively presentation gave casual fans reasons to keep watching. Over time, the game became a weekly ritual for many households.
That success did not mean every game was a classic or every audience member watched from kickoff to the final whistle. The important change was the dependable format: one prominent game, one established night, and a broadcast that turned the slot into part of the league’s routine.
How the program changed networks
ABC carried Monday Night Football from its 1970 debut through the 2005 season. For decades, the series was one of the network’s signature sports broadcasts. Its long run helped establish the idea that a regular-season game could be a major prime-time television event.
Beginning with the 2006 season, ESPN became the primary home of Monday Night Football. The move placed the weekly broadcast on a dedicated sports network and reflected changes in how television rights were packaged. ABC and ESPN are both part of Disney, and ABC has also carried selected simulcasts of games in later seasons.
Despite the network change, the program kept its central promise: a featured NFL game on Monday night. The presentation, broadcast team, and schedule have evolved over the years, but the name still refers to a continuing weekly series rather than one particular historic game.
For a quick timeline, these milestones clarify the program’s history:
| Milestone | What happened | Why it matters |
|---|---|---|
| September 21, 1970 | ABC aired Browns–Jets, with Cleveland winning 31–21. | The first game in the regular Monday Night Football series. |
| 1970–2005 seasons | ABC carried the program. | The show became a long-running part of ABC’s sports lineup. |
| 2006 season onward | ESPN became the primary broadcaster. | The series moved to a cable sports network. |
| Later seasons | Some games were also shown on ABC. | Simulcasts gave broadcast-TV viewers access to selected matchups. |
What people often get wrong about the start date
A common mix-up is treating the first Monday night NFL game as the same thing as the debut of Monday Night Football. The league had played games on Mondays before ABC launched its series. The key date, September 21, 1970, marks the program’s first broadcast and the beginning of its regular television identity.
Another source of confusion is the phrase “Monday night game.” It can mean any NFL game scheduled for Monday, including contests outside the regular series. Monday Night Football is the specific branded broadcast, with a history tied to ABC’s 1970 launch and its later ESPN run.
It is also easy to assume the program has always aired on the same network. ABC’s original run ended after the 2005 season, when ESPN took over as the primary carrier. Because some games have later appeared on both networks, current listings can make the broadcast arrangement seem less straightforward than the historical timeline.
Useful distinction: the date the series began, the channel carrying a particular game, and the day an NFL game is played are related facts, but they are not interchangeable. Keeping them separate prevents confusion when looking up the show’s history or a current schedule.
How to identify a Monday Night Football broadcast
If you are checking an old game, start with its date and broadcast listing. A Monday kickoff alone does not prove that the game was part of the named series, especially for earlier seasons or special schedule changes. Look for the program title or the network’s game listing to confirm how it was presented.
- Check the season and date. The series began in 1970, but Monday games existed before that year.
- Identify the broadcaster. ABC aired the series through the 2005 season; ESPN became the primary home starting in 2006.
- Confirm the program name. A Monday game may be a special or separately branded broadcast rather than a regular installment.
- Check for simulcasts. In some seasons, a game shown on ESPN has also aired on ABC.
This approach is useful when comparing historic records, searching for a replay, or confirming which channel carried a matchup. It also helps separate the series’ long history from the changing details of individual NFL schedules.
Why the 1970 debut still matters
The first broadcast established a template that outlasted the original network and the people who introduced it. A weekly prime-time game gave the NFL a recognizable television event outside the traditional weekend schedule. It also showed how presentation and announcer personalities could shape the way fans experienced a game.
The lasting impact is not simply that football was played on a Monday. The innovation was packaging a regular game as a consistent national program, complete with a distinctive broadcast style. That combination made Monday night a lasting part of the NFL viewing week.
So, if you are looking for the short version, remember the date and result: September 21, 1970; Cleveland 31, New York 21. ABC’s broadcast began a series that later moved to ESPN, while keeping Monday night football in the national conversation for generations of fans.
Monday Night Football started on September 21, 1970, when the Browns beat the Jets 31–21 in ABC’s first broadcast. The series made a regular prime-time NFL game a weekly event and later moved from ABC to ESPN.
For a quick history reference, keep the debut date, matchup, and network timeline together. If you are researching a specific Monday game, check its broadcast listing too; not every Monday NFL game was part of the branded series.
