The Flintstones cartoon wasn’t initially based on anyone.
The show was about a couple, their child, and a dog living in prehistoric times.
However, as the show progressed, Hanna-Barbera company founder Joseph Hanna thought it looked too much like the comic strip “Blondie,” so he added a working-class spin by blatantly copying the look, voices, and personalities of Ralph and Alice Kramden of “The Honeymooners.”
It still didn’t mesh, so he took it a step further, he added Barney and Betty Rubble to mimic the roles, personalities, and voices of Ed and Trixie Norton, too.
Now he had a hit, and “The Flintstones” ran in a primetime slot for six years and has been in syndication ever since.
