McDonald's Corporation (NYSE: MCD), informally known as Golden Arches or Mickey D's, is the world's largest chain of hamburger fast food restaurants, serving around 64 million customers daily. Headquartered in the United States, the corporation was founded by businessman Ray Kroc in 1955 after he purchased the rights to a small hamburger chain operated by the eponymous Richard and Maurice McDonald.
A McDonald's restaurant is operated by either a franchisee, an affiliate, or the corporation itself. The corporation's revenues come from the rent, royalties and fees paid by the franchisees, as well as sales in company-operated restaurants.
McDonald's primarily sells hamburgers, cheeseburgers, chicken, french fries, breakfast items, soft drinks, shakes and desserts. In response to changing consumer tastes, the company has expanded its menu to include salads, wraps and fruit.
