As of 2015, the most popular Pepsi products are Pepsi, Mountain Dew, Diet Pepsi and Diet Mountain Dew. All four beverages are among the 10 highest-selling soft drinks in the world, coming in at third, fourth, seventh and eighth place respectively.
PepsiCo was formed in 1965 out of a merger between Pepsi-Cola Company and Frito-Lay, Inc. The company makes snack foods and beverages, including soft drinks. Its historic competitor in the area of soft drinks is the Coca-Cola Company. Though PepsiCo outsells Coca-Cola in overall sales, Coke and Diet Coke are still more popular than competing Pepsi products in the global market.
