Which Fortune 500 company introduced Cheerios cereal in 1941?

General Mills introduced Cheerios cereal in 1941.

The cereal was originally marketed as CheeriOats, but the name changed to Cheerios in 1945 after a trademark dispute. It became one of General Mills’ best-known breakfast brands and remains widely associated with toasted oat cereal.

General Mills is a major American food company headquartered in Golden Valley, Minnesota. Its portfolio has included cereal, baking products, snacks, yogurt, and packaged meals. Cheerios is sometimes confused with similar oat-based cereals from Kellogg’s or Quaker, but the Cheerios brand belongs to General Mills.

A related milestone is General Mills’ introduction of the first Cheerios television advertising campaign in the 1940s, helping establish the cereal as a family breakfast staple.
