KFC is the world's largest chain of fried chicken fast food restaurants, headquartered in Kentucky, United States. It was founded in 1930 by Colonel Harland Sanders and has since expanded to over 17,000 locations across 105 countries. KFC was initially very successful and became the second largest restaurant chain after McDonald's through franchising in the United States and overseas expansion. However, some marketing mistakes like a poor Chinese translation and food safety issues have challenged KFC's reputation in recent decades.
