The idea of The Flintstones started after Hanna-Barbera produced The Huckleberry Hound Show and The Quick Draw McGraw Show. Although these programs were successful, they did not have the same wide audience appeal as their previous theatrical cartoon series Tom and Jerry, which entertained both children and the adults that accompanied them. However, since children did not need their parents' supervision to watch television, Hanna-Barbera's output became labeled "kids only". Barbera and Hanna wanted to recapture the adult audience with an animated situation comedy.[16]
The show imitated and spoofed The Honeymooners.[19] William Hanna admitted that "At that time, The Honeymooners was the most popular show on the air, and for my bill, it was the funniest show on the air. The characters, I thought, were terrific. Now, that influenced greatly what we did with The Flintstones ... The Honeymooners was there, and we used that as a kind of basis for the concept."[citation needed] However, Joseph Barbera disavowed these claims in a separate interview, stating that, "I don't remember mentioning The Honeymooners when I sold the show. But if people want to compare The Flintstones to The Honeymooners, then great. It's a total compliment. The Honeymooners was one of the greatest shows ever written."[20] Jackie Gleason, creator of The Honeymooners, considered suing Hanna-Barbera Productions, but decided that he did not want to be known as "the guy who yanked Fred Flintstone off the air".[21][22] Another influence was noted between during Hanna-Barbera's tenure at MGM; where they were in a friendly competition with fellow cartoon director Tex Avery. In 1955, Avery directed a cartoon entitled "The First Bad Man" (narrated by cowboy legend Tex Ritter). The cartoon concerned the rowdy antics of a bank robber in stone-age Dallas. Many of the visual jokes pre-dated similar ones used by Hanna-Barbera in the Flintstones series, many years later. Many students of American animation point to this cartoon as a progenitive seed of the Flintstones.
Barbera explained that selling the show to a network and sponsors was not an easy task
“ Here we were with a brand new thing that had never been done before, an animated prime-time animated show. So we developed two storyboards; one was they had a helicopter of some kind and they went to the opera or whatever, and the other was Fred and Barney fighting over a swimming pool. So I go back to New York with a portfolio and two half-hour boards. And no-one would even believe that you'd dare to suggest a thing like that, I mean they looked at you and they'd think your crazy. But slowly the word got out, and I used the presentation which took almost an hour and a half. I would go to the other two boards and tell them what they did, and do all the voices and the sounds and so-on, and I'd stagger back to the hotel and I'd collapse. The phone would ring like crazy, like one time I did Bristol-Myers, the whole company was there. When I got through I'd go back to the hotel the phone would ring and say "the president wasn't at that meeting, could you come back and do it for him." So I had many of those, one time I had two agencies, they'd fill the room I mean God about 40 people, and I did this whole show. I got to know where the laughs were, and where to hit it, nothing; dead, dead, dead. So one of the people at Screen Gems said "This is the worst, those guys...." he was so angry at them. What it was, was that there were two agencies there, and neither one was going to let the other one now they were enjoying it. But I pitched it for eight straight weeks and nobody bought it. So after sitting in New York just wearing out, you know really wearing out. Pitch, pitch, pitch, sometimes five a day. So finally on the very last day I pitched it to ABC, which was a young daring network willing to try new things, and bought the show in 15 minutes. ”
