According to WDW Magazine, the story essentially goes that in the 1950s, a company called Alex Foods was the main food supplier for the park's restaurants. One of those restaurants was sponsored by Frito-Lay and called Casa de Fritos (which was in the location where Rancho del Zocalo is now).

In the 1960s, an Alex Foods salesman noticed staff at Casa de Fritos throwing out unused tortillas. So, he suggested they cut up the tortillas into triangles, fry them, and season them (allegedly inspired by a Mexican snack called totopos).

The "invention" was a hit, and the item was added to the menu. Some years later, a VP for Frito-Lay saw how big a success the snack was, so the company decided to start making and selling it outside the park in Southern California. Alex Foods was eventually cut out of the deal, and then Frito-Lay moved production to their own factory in Tulsa and started selling Doritos nationwide.
