On March 11, 1989, “Cops,” a documentary-style television series that follows police officers and sheriff’s deputies as they go about their jobs, debuts on Fox. “Cops” went on to become one of the longest-running shows in television history. It went off the air in 2020. The show, which was created by John Langley and Malcolm Barbour, was a pioneer in reality television. Crews with camcorders followed law enforcement officers on patrol, tracking down suspects and making arrests. The show was unscripted, which worked in Langley and Barbour’s favor when they pitched the original concept to Fox: At the time, there was a writers’ strike in Hollywood, and the network needed new programming that wouldn’t require writers. In 1989, the debut episode of “Cops” featured the men and women of the Broward County Sheriff’s Department in Florida. The show aired over 1,000 episodes and filmed in 140 U.S. cities, as well as international locations including London and Hong Kong. With its widely recognized theme song, “Bad Boys” by the reggae group Inner Circle, “Cops” had spawned numerous imitators in addition to parody shows.
