American food and beverage company that took its name in 1965, when the Pepsi-Cola Company merged with Frito-Lay, Inc. The company's headquarters are in Purchase, New York.

The first Pepsi-Cola was created by Caleb D. Bradham (1866–1934), a pharmacist in New Bern, North Carolina. Hoping to duplicate the recent success of Coca-Cola, Bradham named his sweet, cola-flavoured, carbonated beverage Pepsi-Cola in 1898. The drink proved popular, so in 1902 Bradham incorporated the Pepsi-Cola Company. After many years of moderate prosperity, the company fell on hard times after World War I and was reorganized and reincorporated several times in the 1920s.

In 1931 the company's trademark and assets were picked up by Charles G. Guth (1876–1948), founder of the modern Pepsi-Cola. He established a new Pepsi-Cola Company, had a chemist formulate a better drink, set up new bottling operations, and began merchandising a hugely successful 12-ounce bottle for five cents. Guth was also president of Loft, Incorporated, a candy manufacturer and soda-fountain chain (founded 1919), and in legal battles in 1936–39 he lost a controlling interest in the Pepsi-Cola Company to the new management of Loft. When in 1941 the Pepsi-Cola Company was merged into Loft, the name Loft, Inc., was changed to Pepsi-Cola Company.

In 1950 Alfred N. Steele (1901–59), a former vice president of Coca-Cola Company, became chief executive officer. His emphasis on giant advertising campaigns and sales promotions increased Pepsi-Cola's net earnings 11-fold during the 1950s and made it the chief competitor of Coca-Cola. (After Steele's death, his wife, actress Joan Crawford (Crawford, Joan), became an active director of the company.) In 1965 Pepsi-Cola merged with Frito-Lay, Inc., the maker of snack foods such as Fritos, Doritos, Lay's potato chips, and Rold Gold pretzels. The newly enlarged company diversified further with the purchase of three restaurant chains, Pizza Hut, Inc. (1977), Taco Bell Inc. (1978), and Kentucky Fried Chicken Corp. (1986; now called KFC), and Seven-Up International (1986), but in 1997 the restaurant chains were spun off into a new, separate company called Tricon Global Restaurants, Inc. PepsiCo acquired the Tropicana and Dole juice brands from the Seagram Company (Seagram Company Ltd.) in 1998. In 2001 PepsiCo merged with the Quaker Oats company (Quaker Foods and Beverages) to form a new division, Quaker Foods and Beverages. With the merger PepsiCo's popular brands included Pepsi cola, Frito-Lay snack products, Lipton Tea, Tropicana juices, Gatorade sports drinks, Quaker Oats cereals, and Rold Gold pretzels.
