In 1975, PepsiCo ran a marketing campaign called "The Pepsi Challenge." It was a blind taste test where shoppers at malls and other public areas were asked to drink out of two different white cups - one cup contained Pepsi, while the other contained Coca-Cola. After drinking both, the shoppers were asked to select which drink they preferred. The results revealed that most Americans prefer Pepsi.
