The Chicago Bozo franchise was the most popular and successful locally produced children's program in the history of television. It also became the most widely known Bozo show as WGN-TV became a national cable television Superstation. WGN-TV Chicago's "Bozo" show debuted on June 20, 1960 starring Bob Bell on a live half-hour program weekdays at noon, performing comedy sketches and introducing cartoons. The series was placed on hiatus in January 1961 to facilitate WGN's move from Tribune Tower in downtown Chicago to 2501 West Bradley Place on the city's northwest side. WGN-TV's "Bozo's Circus" debuted on September 11, 1961.
