After two seasons, "The Bugs Bunny Show" moved to Saturday mornings, where it remained in one format or another for nearly four decades. The show's title and length changed regularly over the years, as did the network: both ABC and CBS broadcast versions of "The Bugs Bunny Show". In 2000, the series, by then known as "The Bugs Bunny & Tweety Show", was canceled after the "Looney Tunes" and "Merrie Melodies" libraries became the exclusive property of the Cartoon Network family of cable TV networks in the United States. Reruns of "The Bugs Bunny and Tweety Show" were aired on the Canadian channels Teletoon and Teletoon's sister channel, Teletoon Retro (until 2015 when Teletoon Retro signed off). Prior to Teletoon and Teletoon Retro, CBC Television (1960–1975) and Global Television Network (1978–1982, 1990-2000) aired the show. In Australia, episodes of the show was divided into 3 networks with most episodes aired on Nine Network and some episodes were divided on Network Ten and Seven Network since its debut.
