PepsiCo is one of the world’s largest producers of soft drinks. Its most famous brand is Pepsi but its products also include Mountain Dew, Aquafina, 7up, Gatorade and Tropicana, among many other household names. Pepsi was first made in the 1890s by a pharmacist called Caleb Bradham. He wanted to create a tasty drink that boosted energy and helped with digestion. Since its creation, it has been involved in perhaps the world’s greatest business rivalry, with Coca Cola, which unsuccessfully tried to buy Pepsi three times in the 1930s. The company has over 200,000 employees worldwide and generates $50 billion of revenue a year. PepsiCo’s website says: “Our mission is to be the world's premier consumer products company focused on convenient foods and beverages.”
