Cheetos were invented in 1948 by Fritos creator Charles Elmer Doolin, who cooked early test batches in the Frito Company's Dallas, Texas-based research and development kitchen. The cheese-flavored snack sold quickly, but Doolin did not have the production or distribution capacity to support a nationwide launch. This led Doolin to partner with potato chip businessman Herman W. Lay for marketing and distribution, and Cheetos were introduced nationally in the U.S. in 1948.
