Unlike its sister cereal Cocoa Pebbles, Fruity Pebbles has undergone many formula changes, additions and variants. The cereal started out with three colors - orange, red, and yellow - and natural orange, lemon and tangerine flavors, but were later flavored in natural orange and artificial lemon and cherry.

It was introduced nationwide in 1971. After some limited test marketing, the Pebbles cereals rolled out nationwide in 1971, the same year that a new cartoon, The Pebbles and Bamm-Bamm Show, premiered. Fred and Barney, meanwhile, gobbled up the cereal in animated ads like this one here.

Rather than waste the OKs machinery, Kellogg's executive William LaMothe decided to pivot from OKs to a fruit-flavored O-shaped oat cereal. The idea took off, and fruity flavors became the most exciting innovation in breakfast food. Post later followed suit, transforming crispy rice cereal into Fruity Pebbles.

Cocoa Pebbles pieces used to be flat little flakes, but now they have a similar puffed-up 'crispy' texture - like Cocoa Krispies. As a kid, I ate a lot of Cocoa Krispies because I thought they were the most chocolatey cereal, but then one day I tried Cocoa Pebbles and fell in love.

Granula The first cold breakfast cereal, Granula (not the same as granola), was invented in the United States in 1863 by James Caleb Jackson, operator of Our Home on the Hillside which was later replaced by the Jackson Sanatorium in Dansville, New York.

Granula wasn't much like the cereal we eat today. The first manufactured breakfast cereal, it was developed in 1863 by a doctor and health reformer named James Caleb Jackson. Jackson believed, as many did at the time, that sicknesses were based in the digestive system.

Granula The first hot ground oatmeal cereal was created as early as 1854 by Ferdinand Schumacher, a German immigrant from Ohio, and the first cold breakfast cereal, “Granula” (which had to be soaked overnight for it to be palatable), was the invention of New Yorker James Caleb Jackson in 1863.

Please tell me my cereal isn't changing! Sorry, but it is. General Mills said it is eliminating artificial colors and flavors from its cereals, replacing them with fruit and vegetable juices, natural dyes and spice blends.
