why does the nfl not play on saturday
Sports Broadcasting Act of 1961 The law has been interpreted to include the so-called "blackout rules" which protect a home team from competing games broadcast into its home territory on a day when it is playing a game at home, and from having to broadcast games within its home market area that have not sold out. It also, in effect, protects high school football and college football game attendance by blacking out pro football games locally on Friday evenings and Saturdays during those sports' regular seasons; these measures effectively outlawed the broadcasting (and, in practice, the playing) of NFL games on those days, since virtually all of the country is within 75 miles of at least one high school game on every Friday night in September and October.
History of Monday Night Football 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).
