The NFL Network's coverage was not the first time that NFL games were covered on Thursday or Saturday. ABC televised occasional Thursday night games from 1978 to 1986 as part of its "Monday Night Football" package. Prior to the new contract, ESPN carried a handful of sporadic Thursday night games (usually those displaced from Sunday night) and the broadcast networks used to air several national games on Saturday afternoons in mid-to-late December after the college football regular season ended. Incidentally, the only reason the league is even allowed to televise football games on Saturday night stems from a legal loophole: the league's antitrust exemption, the Sports Broadcasting Act of 1961, was written when the NFL regular season ended in mid-December, and as such, it contains specific language that prohibits televising NFL games in most markets on Friday nights and all day on Saturdays between the second week of September and the second week of December, to protect high school and college football. Since most high school and college seasons have ended by mid-December, other than bowl games, there has been little desire to close this loophole, even though the regular season has expanded well beyond mid-December since the law's passage.
