Short answers, pulled from the story.
Frito-Lay was formed in September 1961 through the merger of The Frito Company and H.W. Lay & Company. The Frito Company was founded by Charles Elmer Doolin in 1932, and H.W. Lay & Company was established by Herman Lay in 1939.
Frito-Lay merged with the Pepsi-Cola Company on the 8th of June, 1965, after shareholders of both companies approved the deal. The merger created a new company called PepsiCo, Inc., and Frito-Lay has operated as a wholly owned subsidiary of PepsiCo ever since.
Frito-Lay's primary brands include Fritos corn chips, Lay's and Ruffles potato chips, Doritos and Tostitos tortilla chips, Cheetos cheese-flavored snacks, Rold Gold pretzels, Sun Chips, and Cracker Jack popcorn. Each of its primary brands generated annual worldwide sales over $1 billion in 2009.
Doritos launched in 1966 as a tortilla chip positioned for flavor, but consumers initially found it too bland. Frito-Lay relaunched it in Taco and then Nacho Cheese flavors, after which Doritos became the second best-selling Frito-Lay product line behind Lay's.
In 1967, Frito-Lay introduced a cartoon mascot called the Frito Bandito, voiced by Mel Blanc. Mexican-American groups including the National Mexican-American Anti-Defamation Committee protested that the character, which wore a sombrero and brandished pistols, portrayed a harmful stereotype. The character was retired in 1970.
In 2009, Frito-Lay products accounted for 40 percent of all savory snacks sold in the United States. In 2018, Frito-Lay North America alone accounted for at least 25 percent of PepsiCo's total annual sales.
