Fruity Pebbles, Ice Cream Pebbles, and Cocoa Pebbles are brands of breakfast cereal introduced by Post Foods in 1971 featuring characters from the animated series The Flintstones as spokestoons.The cereals debuted in 1971. Cocoa Pebbles contains chocolate-flavored crisp rice cereal bits, while Fruity Pebbles contains crisp rice cereal bits that come in a variety of fruit flavors with a sugar content of 9 grams per serving for Fruity Pebbles and 10 grams per serving for Cocoa Pebbles. It is the oldest cereal brand based on characters from a TV series or movie.
Fruity Pebbles and Cocoa Pebbles Cereal were reintroductions of a low share of market Post children's cereal brand called Sugar Rice Krinkles. The Product Group Manager at the time, Larry Weiss, licensed use of The Flintstones for cereal from Hanna-Barbera in an attempt to reinvigorate the children's cereal business for Post Cereals. Prior to that time, character licensing had been used for promotion, but there had never been a brand created around a media character. The brand was marketed despite internal concern it would be a fad and not last more than a year. Cocoa Pebbles and Fruity Pebbles were simultaneously introduced on the West Coast in 1969 and strong consumer demand led to national distribution. The brand has been one of the most consistent best sellers ever since.
The original working names for the companion cereals were Flint Chips and Rubble Stones, consistent with the appearance of the cereal and The Flintstone's Stone Age imagery. Frank Corey, Benton & Bowles' creative head for the Post Cereal business suggested the alternative names Cocoa Pebbles and Fruity Pebbles, which were adopted.
The basic product retained the Sugar Rice Krinkles form, using the existing expander process and Battle Creek production facilities. The flavors, colors and other product formulations were carefully developed by Battle Creek product experts supported by marketing using the Linescale research technique. The objective was to create product characteristics which matched the expectations of both children and parents for what The Flintstones cereals should look and taste like. After many iterations, the Cocoa Pebbles formula was set and has remained largely unchanged over the years. Fruity Pebbles also remained essentially unchanged for decades. In recent years some additions and variations have been made to the Fruity Pebbles product formulation. The Canadian version came in the form of corn puffs in Pebble shapes.
