The 1993 NFL season was the 74th regular season of the National Football League. It was the only season in league history where all NFL teams played their 16-game schedule over a span of 18 weeks. After the success of expanding the regular season to a period of 17 weeks in 1990, the league hoped this new schedule would generate even more revenue. However, teams felt that having two weeks off during the regular season was too disruptive for their weekly routines, and thus it reverted to 17 weeks immediately after the season ended.
When new TV contracts were signed in December 1993, CBS lost their rights to the then-fledgling Fox Network.
The season ended with Super Bowl XXVIII when the Dallas Cowboys defeated the Buffalo Bills for the second consecutive year. This remains the only time both Super Bowl participants have been the same for consecutive years. The Cowboys became the first team to win a Super Bowl after losing their first two regular season games. Taken from http://en.wikipedia.org/wiki/1993_NFL_season.
