“Turn-On,” a surreal sketch comedy show that aired on ABC on February 5, 1969, became one of the most infamous flops in television history after its controversial content led to immediate cancellation. Featuring rapid-fire, off-color humor and no traditional set, the show was so poorly received that several affiliates refused to finish airing it, with some pulling it mid-broadcast. Despite high expectations from the creators of Laugh-In, “Turn-On” was deemed too risqué for its time, leaving its mark as one of TV’s most notorious failures.
