Doritos is an American style tortilla, which has been produced by frito lay, a wholly-owned subsidiary of Pepsi since 1964. The original Doritos had no seasoning. The first is taco, which was released in 1967, but other flavors have been introduced for the first time since. The concept of Doritos originated in a restaurant in Disneyland.

Doritos is also notorious for its marketing campaigns, including many of the ads broadcast during the super bowl.

The original product was made in Casa de Fritos (now Rancho del Zocalo) at Disneyland in Anaheim, California, in the early 1960s. The company owns a restaurant that uses redundant tortillas and draws original ideas from the traditional Mexican snack totopo, shredding them, frying them, and adding basic seasoning, similar to jalapeno, but dry in this case. Arch West was frito lay's vice president of marketing at the time and noted their popularity. In 1964, he entered into a deal with Alex foods, the supplier of many items for Casa de Fritos in Disneyland, and produced the chips in a short period of time in some parts of the country, but later transferred them to the Tulsa factory due to insufficient production.

Doritos was released nationwide in 1966, the first nationwide tortilla in the United States.

According to international information resources, in 1993, Doritos's retail sales amounted to $1.2 billion, accounting for a third of frito lay's sales in that year. Still, among the most expensive redesigns in frito lay's history, the company spent $50 million in 1994 redesigning Doritos to make the chip 20 percent larger, 15 percent thinner, and the edges of the chip rounded. Roger J. berdusco, vice president of chip marketing for tortillas, said the main reason for the change was "greater competition with larger, more flavored restaurant tortillas". The design change was the result of a two-year market study involving 5000 people who ate chips. The new design makes every chip have round corner, which makes it easier to eat, and reduces the scrap caused by corner fold. Each slice is also seasoned more to make it stronger. The redesigned chip has been released in four flavors since January 1995.

In the United States, frito lay eliminated trans fats from all Doritos varieties in 2002. In the same year, the Doritos brand began to comply with the labeling regulations of the U.S. Food and drug administration, four years after the Regulations became mandatory.

The company was sued in 2003 by Charles Grady, who claimed his throat had been damaged by eating Doritos. According to him, the chip's shape and rigidity make it dangerous. Grady tried to take as evidence a study by a former chemistry professor that calculated how best to swallow debris safely. The Pennsylvania Supreme Court later ruled that the study did not meet scientific standards and could not be presented as evidence.

In 2005, Doritos sales in the United States fell 1.7% to $595 million. To boost sales in 2006, the company launched several new flavors, new labels and more bilingual ads. Joe Ennen, vice president of frito lay, described it as "the most important brand reinvention and re launch in Doritos' 38 year history".

On February 21, 2013, the Doritos logo was changed again and the slogan "for the bold" was adopted.

In 2015, Doritos launched a limited edition rainbow Doritos product, which can only be used by users who donate more than $10 to it gets better project, a non-profit organization that supports LGBT youth. The promotion raised $100000 for the organization and caused controversy.

There are concerns that the oils, flavourings and additives used may not be healthy.
