The first McDonald's franchise opened in Des Plaines, Illinois, on April 15, 1955.
By the 1970s, McDonald's had grown into an increasingly popular fast-food establishment.
The Quarter Pounder, Quarter Pounder with cheese, and Egg McMuffin were also added to the menu.
In the 1970s, less than a decade into its operation under businessman Ray Kroc, McDonald's was already a thriving company that had served millions of customers.
That year, he also founded McDonald's System, Inc., which would become the McDonald's Corporation we know today.
