Show (which had aired on CBS since 1966) to create The Bugs Bunny/Road Runner Hour. The standard Bugs Bunny Show opening and the announcer's introduction of Bugs Bunny ("that Oscar-winning rabbit!") were directly followed by the rabbit's saying, "...and also starring my fast feathered friend, the Road Runner", after which The Road Runner Show's theme was played. The Bugs Bunny/Road Runner Hour combined re-edited bridging sequences from both shows to link the seven cartoons featured in each episode. The bridging sequences would be edited further in later versions of the Bugs Bunny/Road Runner Hour. In 1971, The Road Runner Show moved to ABC, and a reconstituted half-hour Bugs Bunny Show aired on CBS, featuring re-edited versions of the bridging sequences and a different grouping of cartoons. In 1973, The Bugs Bunny Show returned to ABC for two seasons, only for CBS to re-acquire both shows and bring back The Bugs Bunny/Road Runner Hour in 1975. In 1976, Sylvester and Tweety were featured in their own Sylvester and Tweety Show for one year, necessitating the removal of most of the Tweety and/or Sylvester cartoons on Bugs Bunny/Road Runner that season. Also that year, a weekly half-hour prime-time edition of The Bugs Bunny/Road Runner Show briefly aired on CBS' Tuesday night schedule from April through June. The Bugs Bunny/Road Runner Hour became The Bugs Bunny/Road Runner Show in November 1977 after CBS added another half-hour to the runtime. In 1981, a companion Sylvester & Tweety, Daffy, and Speedy Show was added to the CBS schedule, which included a number of later cartoons produced by a reestablished Warner Bros. Cartoons studio from 1967 to 1969. The following year, this new companion series was canceled, and its cartoons were incorporated into The Bugs Bunny/Road Runner Show, which was broadcast as two separate hour-long programs on Saturday mornings (for the second program, the show's opening titles were re-animated). In 1983, CBS returned the show to 90 minutes and the bridging sequences were dropped. The following year, the "This Is It" opening was jettisoned altogether; a new title sequence (created from clips of the cartoons) and new theme song ("It's Cartoon Gold"), composed by Steve Zuckerman with lyrics by John Klawitter, introduced the show. Final Saturday morning years, 1985–2000 CBS gave up the rights to broadcast the Warner Bros. cartoons following the 1984–1985 season, and as a result, the show moved back to ABC, where it
