Sanders officially went into the chicken franchising business in 1952, when he sold his restaurant after it was by-passed by a major interstate. He traveled the U.S. selling his concept of pressure-cooked chicken for a 5-cent royalty fee for every chicken sold.By 1955, he established Kentucky Fried Chicken.In the early 1960s, the KFC franchise totaled 600 stores in the U.S. and Canada. In 1964, Sanders sold his share for $2 million to a group of investors, turning KFC into a fast-growing corporation. In 1971 it was acquired by Heublein Inc. and was later sold to R.J. Reynolds Industries. In 1986, KFC was purchased by PepsiCo Inc. and was placed under its restaurant company Tricon Global Restaurants. In 2002, Tricon changed its name to Yum! Brands, now the largest restaurant company in the world with 32,500 stores in more than 100 countries.
