McDonald's Corporation, doing business as McDonald's, is an American multinational fast food chain, founded in 1940 as a restaurant operated by Richard and Maurice McDonald, in San Bernardino, California, United States. They rechristened their business as a hamburger stand and later turned the company into a franchise, with the Golden Arches logo being introduced in 1953 at a location in Phoenix, Arizona. In 1955, Ray Kroc, a businessman, joined the company as a franchise agent and, in 1961, bought out the McDonald brothers. Previously headquartered in Oak Brook, Illinois, it moved to nearby Chicago in June 2018. McDonald's is also a real estate company through its ownership of around 70% of restaurant buildings and 45% of the underlying land. McDonald's is the world's second largest fast food restaurant chain by number of locations, surpassed by Chinese chain Mixue Ice Cream & Tea as of September 2024. McDonald's serves over 69 million customers daily in over 100 countries in more than 40,000 outlets as of 2021. McDonald's is best known for its hamburgers, cheeseburgers and french fries, although their menu also includes other items like chicken, fish, fruit, and salads. Wikipedia
