The Flintstones made its television debut on today’s date, September 30, 1960.
I remember watching that night. I was 7 and found it a completely satisfying intellectual experience.
The show was a hit, finishing the season at #18 in the Neilsen ratings, right behind Bonanza. Unlike Bonanza, which went on to be one of the very highest rated shows, the Flintstones never again finished in the top 20 and went off the air in April 1966. (The characters have been revived for many other productions since then.)
When originally aired, the episodes ended with a commercial showing Fred and Wilma smoking Winstons. Four decades later, Sierra liked Flintstone brand vitamins. Obviously the better product to be plugging to children.
