The original product was made at the Casa de Fritos at Disneyland in Anaheim, California. Using surplus tortillas, the restaurant cut them up and fried them and added seasoning. The Vice President of Marketing of Frito-Lay noticed their popularity and made a deal to produce the chips for a short time regionally, before Frito-Lay moved production to Tulsa due to overwhelming demand.
"Doritos" were released nationwide in 1966, the first tortilla chip to be launched nationally in the United States. The name derives from the Mexican Spanish doradito, meaning "turned golden or crisp".
