Domino’s was founded in 1960. The restaurant chain’s founder, Tom Monaghan, is one of three people in the world who hold an advanced degree in “Pizza-ology” from the “Domino’s College of Pizza-ology”—a business management program he founded in the ‘80s.

Pizza may have originated in Italy, but countries around the world have developed their own regional spins on the classic food. In Brazil chefs top their pizzas with green peas, the French love fried eggs on their slices, and in China a crust made of mini-hot dogs is surprisingly popular.
