McDonald's, founded in 1940 by Richard and Maurice McDonald and later franchised by Ray Kroc, has grown to become the world's largest fast-food chain with over 36,000 locations and over 1.9 million employees globally. The company focuses on core values of quality, service, cleanliness, and value while adapting its menu offerings to changing customer preferences and facing competition from other fast-food chains. Future risks include adapting to health-conscious consumer demands, new market entrants, and the need for continued brand innovation.
