"On the Buses is a British sitcom that was broadcast on ITV from 1969 to 1973. It was created by Ronald Chesney and Ronald Wolfe, who wrote most of the episodes. It spawned three spin-off feature films and a stage version. Despite the writers' previous successes with The Rag Trade and Meet the Wife with the BBC, the corporation rejected On the Buses, not seeing much comedy potential in a bus depot as a setting. The comedy partnership turned to a friend, Frank Muir, Head of Entertainment at London Weekend Television, who loved the idea; the show was accepted and despite a poor critical reception became a hit with viewers."
