Hanna-Barbera's "The Flintstones" became the first successful prime time animated series in the United States when it premiered in 1960. The show's characters were heavily inspired by the characters on the sitcom "The Honeymooners," which also followed working-class friends and neighbors. "The Flintstones" ran for six years, from 1960 to 1966, and spawned several live-action and animated movies, including the 1994 movie starring John Goodman and Rick Moranis.
"The Flintstones" was known for several running gags and celebrity cameos. One such running joke involved the use of puns about rocks, especially when naming guest stars: Cary Grant became "Cary Granite" and Tony Curtis appeared on the show as the character "Stony Curtis." Another running joke on "The Flintstones" was the fact that Fred and Wilma, despite living in a prehistoric era, had modern conveniences such as record players, vacuum cleaners and dishwashers, all powered by animals.
While "The Flintstones" is often cited as the first sitcom to depict opposite-sex characters sharing a bed, an earlier sitcom had already shown this sleeping arrangement. It was, however, the first animated show to depict a husband and wife sleeping in the same bed. The show also featured a notable subplot about Betty Rubble's infertility and subsequent adoption of Bamm-Bamm.
