Doritos (/dəˈriːtoʊz/) is an American brand of flavored tortilla chips produced by Frito-Lay, a wholly owned subsidiary of PepsiCo.[2][3] The concept for Doritos originated at Disneyland at a restaurant managed by Frito-Lay. In 1966, Doritos became the first tortilla chip available nationally in the United States. The initial flavor was simply toasted corn, followed by taco in 1967, and the now-ubiquitous nacho cheese in 1972.[4][5] The chips are available worldwide in a wide variety of flavors, differing regionally. Doritos has also gained notability for its marketing campaigns, including ads aired during Super Bowls. The Doritos brand is also used for similarly seasoned products, like Doritos 3D and taco shells at Taco Bell, where they're used in Doritos Locos Tacos.
