To a good portion of us both The Flintstones and The Jetsons were mainstays of our afterschool and Saturday morning television viewing. However, back in the 1960's both of these Hanna-Barbera creations were part of the ABC prime-time lineup. The Flintstones were a mainstay on the schedule from 1960 until 1966 while The Jetsons appeared in only the 1962-63 season.

Of course, being on the prime-time schedule there was bound to be some promotion of both shows. And, that's what you'll see after the jump: promotions for both The Flintstones and The Jetsons during their first run. Both of these clips are in black-and-white, even though both shows were produced in color. The Flintstones' promo is for the show's fourth season. The episode featuring Ann-Margret as Ann Margrock was the season premiere. Yes, Virginia, stars lent their voices to cartoons long before The Simpsons.
