Step 1 : Introduction to the question "What does the name of the M&M candy stand for?"
...In 1941, Forrest Mars Sr., of the Mars candy company, struck a deal with Bruce Murrie, son of famed Hershey president William Murrie, to develop a hard shelled candy with chocolate at the center. The name thus stood for “Mars & Murrie” the co-creators of the candy. The partnership allowed the candies to be made with Hershey chocolate, as Hershey had control of the rationed chocolate at the time. The story didn’t end sweetly for Murrie, though. When chocolate rationing ended after the war, Mars bought out Murrie's interest in the product and went on to become one of Hershey’s biggest competitors.
