Flintstones Ad History
When "The Flintstones" went on the air in 1960, ABC promoted the show as an "adult cartoon"--so it found a pair of sponsors selling grown-up products. R.J.Reynolds (Winston cigarettes) and Miles Laboratories (Bactine; One-A-Day vitamins; Alka-Seltzer--now owned by Bayer) sponsored "The Flintstones" for its first few seasons (and yes, the gang did animated spots for the sponsors, including Winston and its famous "filter blend" that "tastes good like a cigarette should"). A few years later, "The Flintstones" moved to an earlier timeslot and ABC found more "family friendly" sponsors (Welch's Grape Juice; Skippy peanut butter; Best Foods/Hellman's mayonaise).
"The Flintstones" was shot in color from the first episode, but ABC--which was a poor third in both the ratings and revenues--had no interest in broadcasting shows in color. ("The Jetsons" was the first ABC series to air in color two years later, but many ABC affiliates broadcast the program in black and white because they lacked the proper color transmission equipment.) ABC remained behind NBC and CBS in color programming until the fall of 1966, when all three networks began airing their entire prime time lineups in full color.
