In 1984, Hanna-Barbera began producing new episodes specifically for syndication; by September 1985, the 24 episodes from the first season were combined with 41 new episodes and began airing in morning or late afternoon time slots in 80 U.S. media markets, including the 30 largest. The 41 new episodes were produced at a cost of $300,000 each, and featured all of the voice actors from the 1962–1963 show. During 1987, 10 additional "season 3" episodes were also made available for syndication. 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. The series' theme song, by composer Hoyt Curtin, became a pop hit in 1986. Animation historian Christopher P. Lehman considers that the series shares its main science fiction theme with "Funderful Suburbia" (1962), a Modern Madcaps animated short. Both feature people involved in space colonization. However, there is a key difference in the nature of the colonization: in "Funderful Suburbia", humans colonize outer space in order to escape the problems of planet Earth, while the Jetsons live in a place where space colonization is already established. Life in outer space is depicted as a fact of life, and the reasons behind humanity's takeover of outer space are never explained. Lehman argues that the series offers no explanation for its science fiction premise and does not directly satirize the social problems of any era. The setting is combined with standard sitcom elements, which serve as the series' main focus. After the announcement of the fall 1962 network television schedule "Time" magazine characterized "The Jetsons" as one of several new situation comedies (along with "The Beverly Hillbillies", "I'm Dickens... He's Fenster", and "Our Man Higgins") that was "stretching further than ever for their situations"; after all the season's new shows had premiered—a season "responding to Minow's exhortations"—the magazine called the series "silly and unpretentious, corny and clever, now and then quite funny."
