CSI later came out with a series called "Wide World of Fights", which has a much broader scope and includes mixed martial arts, kickboxing, and other combat sports footage in addition to some of the fights that were originally part of the "Tuesday Night Fights" compilation series. This series also airs on many of the same stations that carry "Tuesday Night Fights: Knockouts!". CSI also airs old episodes of "Tuesday Night Fights" as part of its "Fight Sports World Championship Boxing" series, which rebroadcasts fights from the past.
