Burger King was founded in 1953 in Florida and was inspired by McDonald's. It was originally called Insta-Burger King and used an Insta-Broiler oven for fast cooking. In 1959 it was bought and renamed to Burger King. In the 1970s it was the first to offer enclosed, air-conditioned seating areas across all locations. It has operated for over 60 years but has experienced ownership changes and financial difficulties at various points in its history.
