It is no secret that McDonald's and Burger King have the biggest, longest-lasting rivalry in fast food history. But did you know, the founder of Burger King actually got his idea for the franchise from McDonald's. Here's the story:

Back in 1940, Dick and Mac McDonald started in the food industry by selling barbecue and hot dogs. The famous Happy Meal didn't come into the picture until much later. They realized their best sellers were those quick grab and go items like burgers and fries, so they ditched their original plan to focus on speedy service. After becoming wildly popular in San Bernardino, California, a man named Ray Kroc came into the picture. He's the one who truly got McDonald's going. 

While McDonald's has always been one of the most successful fast food franchises, Burger King has struggled a bit more than its burger rival. Starting up nearly a decade after McDonald's, Burger King was originally named Insta Burger King. It was similar in theory to McDonald's, but lacked originality and ended up going through a long series of mergers and acquisitions, being bought out by any company willing to risk their money and invest in the franchise. 

Now, both McDonald's and Burger King continue to be two of the most popular and successful fast food joints, but we want to know what you have to say. Take this quiz and we'll guess which one you prefer!
