PepsiCo pairs a global beverage business with an even larger snack food empire. Frito-Lay brands such as Lay's, Doritos and Cheetos dominate salty snacks in many markets, while Quaker adds cereals and grains and the drinks lineup spans Pepsi, Gatorade and Mountain Dew. Food accounts for a bigger share of profit than beverages, which distinguishes the company from its Atlanta rival. A direct-store delivery system, one of the largest in the industry, keeps its products stocked on shelves nearly everywhere.
