Not one and the same. KFC is an American multinational restaurant chain founded by Harlan Sanders in 1952, which mainly sells hamburgers, and fast food such as fries, fried chicken, soda, ice, salad, fruit, etc., while McDonald's is an American multinational restaurant chain founded by the McDonald Brothers in 1940 in Chicago, which mainly sells fast food such as hamburgers, fries, fried chicken, soda, ice, etc., so KFC and McDonald's are not one and the same.
