• "The Flintstones":When it premiered in September 1960, The Flintstones was the first animated prime-time television series. The cartoon about a modern stone-age family was created by the team of William Hanna and Joseph Barbera, and was almost called "The Flagstones." It was also the first cartoon to feature two people of the opposite sex sleeping together in the same bed. The show ended up succeeding beyond anyone’s wildest dreams, running for six seasons and was nominated for an Emmy Award for Outstanding Comedy Series in its debut season.
