September 30th, 1960, ABC premiered TV's first animated prime-time series The Flintstones.
In honor of the anniversary, some Flintstones trivia:
It was loosely based on The Honeymooners, and originally aimed at adults.
The first sponsor was Winston cigarettes. Fred even smoked them, but only in commercials.
The producers considered hillbillies and Indians before settling on cavemen - the pun possibilities were simply too tempting. Stoneway pianos. Polorock cameras. No stone was left unturned.
The Flintstones' baby was going to be a boy - but when a toymaker said he could sell millions of dolls if it were a girl - Pebbles was born.
Barney and Betty later adopted Bam-Bam.
In one script, Fred was supposed to yell, "yahoo!" But actor Allen Reed changed it to Yabbadabbadoo -- reportedly a play on the old Brylcreem slogan, "a little dab'll do yah."
That's a page from my notebook.
