Kellogg's is a company that is best known for its brands of breakfast cereal established in 1906.
In 1979, a cereal box promotion for The Muppet Movie was handled by Kellogg's, on Corn Flakes boxes in Australia. Muppet stickers were included in each box, which could be used to decorate illustrated scenes on the back of the boxes. In the United States, the Muppet Movie cereal box promotion was handled by General Mills, on Cheerios boxes.
Big Bird was featured on the front cover of a collector's edition Corn Flakes box, featuring the street sign for Sesame Street and five of its international counterparts, commemorating Sesame Street's 30th anniversary.
In 2000, Kellogg's cereals offered a series of twenty-four small (usually less than 4") Sesame Street Mini Beans in their cereal boxes. They were based on the 1997 Tyco Beans. The following cereal brands are as followed:
