NFL Classics is a series of videotaped rebroadcasts of National Football League games that air on the NFL Network. The show airs weekly during the offseason and also occasionally during the NFL season. As of the 2010, the series airs on Monday night while Super Bowl Classics airs on Friday night. The program, the first such series to air on any American television network, premiered on May 10, 2007 with a re-air of the Chicago Bears' Monday Night Football comeback victory over the Arizona Cardinals in 2006. NFL Classics is an extension of an earlier series called Super Bowl Classics, which showed full-length re-airs of some of the most memorable Super Bowl games. The NFL is the last United States-based major professional sports league to make such broadcasts available on TV. Previously, NFL Network and ESPN Classic had aired NFL's Greatest Games, 90-minute edited versions using footage from NFL Films. The other major leagues - MLB, NBA, NHL, and NASCAR - have all had games air on ESPN Classic. However, at this time, full-length MLB games are shown on Classic only occasionally, while NHL games are presently aired on NHL Network.
