Who invented Doritos and the key facts
Doritos were invented by Frito-Lay engineer Arch West, who led the development of the first commercial tortilla chip in the United States. Working at Frito-Lay in the early 1960s, West guided the launch of what became a best-selling snack under the name Doritos. This evergreen explainer outlines who invented Doritos, the product origins at Frito-Lay, how the chips were developed, and verified facts about naming, launch timing, and production milestones.
Arch West and the origins of Doritos
Arch West was a Frito-Lay development executive credited with commercializing the tortilla chip and driving the creation of Doritos. While tortilla chips existed in Mexico and were produced at Frito-Lay and PepsiCo plants earlier for in-house sampling, West championed the idea of a nationally marketed, boldly seasoned corn chip. His work in the early 1960s established the product concept, flavor direction, and initial rollout that defined Doritos.
The first Doritos product test
In 1961, Frito-Lay produced the first commercial batch of tortilla chips under the working name Tostitos for a regional test in California. This early version was unseasoned and sold in restaurants. After West’s team pushed for a seasoned product, the company developed a distinct seasoned corn chip and rebranded it as Doritos, a name derived from Spanish for 'little things.'
Flavor development and national launch
The first widely sold Doritos flavor was Taco, introduced in 1966, followed by Nacho Cheese in 1972. The national rollout was led by Frito-Lay marketing and production teams, with West credited for driving the initial concept and helping secure resources for broader distribution. By the late 1960s, Doritos had become a recognizable national brand in the salty snack category.

How Doritos evolved after invention
After the initial concept and test, Doritos grew through iterative flavor testing, plant upgrades, and national marketing. Frito-Lay expanded capacity, introduced additional flavors, and refined the tortilla process to meet rising consumer demand. Throughout this period, Arch West remained closely associated with the product’s early direction, and the brand became a core part of PepsiCo’s portfolio following the merger with PepsiCo in the coming years.
Flavor and format expansion
The product line broadened to include new shapes, sizes, and bold seasonings. Limited-edition and regional flavors were tested, and successful variants were rolled into permanent offerings. This expansion helped Doritos maintain relevance as tastes shifted and new snack categories emerged.
Branding and marketing milestones
Doritos marketing leaned into a spirit of creativity and risk-taking, often highlighting the chip’s bolder seasonings and loud crunch. Campaigns emphasized the snack’s role in social moments, sports events, and late-night routines. Over time, the brand became synonymous with a playful, expressive approach to snacking.
