The Jetsons
Following its prime time cancellation, ABC placed reruns of "The Jetsons" on its Saturday morning schedule for the 1963–1964 season. The program would spend the next two decades on Saturday mornings, with subsequent runs on CBS (1964–65 and 1969–71) and NBC (1965–67; 1971–76; 1979–81 and 1982–83). Beginning in the late 1960s, "The Jetsons" also began airing simultaneously in syndication. Along with fellow Hanna-Barbera production "Jonny Quest" and Warner Bros.' "Looney Tunes" shorts, "The Jetsons" is one of the few series to have aired on each of the Big Three television networks in the United States.
