The curious case of missing Pebbles Flintstone in FRUITY PEBBLES and COCOA PEBBLES?

Fads come and go in the food business. One thing I still see after all these years is Popeye spinach in a can by Allen Canning Company. Popeyes spinach in a can has been around since 1965. I still am not brave enough to try it. Then there are Flintstones Chewable Vitamins introduced in 1968 by Miles Laboratories (now Bayer AG) and taste sweet like candy.

In 1971, Post created PEBBLES cereal. In that same year Hanna-Barbera’s “The Pebbles and Bamm-Bamm Show” made its debut. The show featured Sally Struthers as Pebbles. She was Fred Flintstone’s little girl before she became Archie Bunker’s little girl. Throughout my youth, FRUITY PEBBLES and COCOA PEBBLES always featured both Fred Flintstone and Barney Rubble as the spokestoons on the cereal boxes and in TV commercials. But where is Pebbles? Why call a cereal PEEBLES and not have Peebles on it? You can read “An Insider’s History of Post’s Pebbles Cereal” by Scott Shaw in RetroFan #21 from TwoMorrows Publishing.

Launched in 1971 after Post secured licensing rights from Hanna-Barbera, PEBBLES cereal was the first brand ever created around a TV show character. One of the most revered cartoons of all time, “The Flintstones” aired on prime-time television from 1960 to 1966, and the characters have returned in countless specials and films. The cereal was named for Fred and Wilma Flintstone’s daughter Pebbles.

From the first bowl of PEBBLES cereal was poured in 1971 to today, the brand has captured hearts and minds, growing in the process to become the No. 1 selling kids cereal brand with more than 1.4 billion bowls eaten annually.
