It Was Created in 1971
Creator Garry Marshall first had the idea for this sitcom in 1971. He wanted to write it and create it, but the bigwigs at Paramount said that they wanted to set the show in the 20s or 30s. Marshall, knowing little to nothing about either decade, said he knew a lot more about life in the 50s since that’s when he did the primary bulk of his own growing up. That’s where the idea was created.
