With the successes of Milky Way, Snickers, and 3 Musketeers under his belt, Forrest Mars had something new in store in 1941 when he introduced M&M's candies. The original M&Ms were actually made with a competitor's product, Hershey chocolate, since chocolate was rationed at the time and Hershey was in charge. The other M stands for Bruce Murrie, son of Hershey's president. The original M&M colors were brown, yellow, green, red, and violet. By the time M&M's started stamping Ms on each candy, violet had been traded out for tan. In 1976 orange replaced red, but red came back 11 years later, adding a sixth color to each pack. In 1995 Mars asked customers to choose the replacement for tan, and blue was the winner. Many different varieties of M&Ms have appeared over the years, starting with Peanut M&MS in the 40s. They have become so popular that they've spawned cartoon characters and countless joint marketing campaigns.
