PepsiCo Inc. is an American multinational food and beverage corporation headquartered in Purchase, New York, United States, with interests in the manufacturing, marketing and distribution of grain-based snack foods, beverages, and other products. PepsiCo was formed in 1965 with the merger of the Pepsi-Cola Company and Frito-Lay, Inc. PepsiCo has since expanded from its namesake product Pepsi to a broader range of food and beverage brands, the largest of which include an acquisition of Tropicana in 1998 and a merger with Quaker Oats in 2001—which added the Gatorade brand to its portfolio.
