By the 1950s, the idea of fast food was just starting to leave its mark on the American food industry. Brothers Dick and Mac McDonald had launched their eatery, McDonald’s, back in the 1940s, and according to the corporate website, they quickly found success with their method of drive-in dining.
It turns out that the brothers might have had more of an impact on the industry than they realized because another fast-food giant supposedly found inspiration after seeing their restaurant. Arts Tribune reports that Keith Kramer and his wife’s father, Matthew Burns, actually founded Insta Burger King after seeing the McDonald brothers’ San Bernardino, California restaurant back in the early 1950s.
Today, Burger King and McDonald’s are widely known for serving similar menu items; specifically, burgers and French fries. As of 2019, McDonald’s was the biggest fast-food chain in the country, per QSR Magazine, while Burger King ranked at no. 7.
