Who would have guessed that the idea for "M&M's"® Plain Chocolate Candies was born in the backdrop of the Spanish Civil War? Legend has it that on a trip to Spain, Forrest Mars Sr. encountered soldiers who were eating pellets of chocolate that were encased in a hard sugary coating to prevent them from melting. Inspired by this idea, Mr. Mars went back to his kitchen and invented the recipe for "M&M's"® Plain Chocolate Candies.
First sold to the public in 1941, "M&M's"® Plain Chocolate Candies became a favorite of American GIs serving in World War II. Packaged in cardboard tubes, "M&M's"® Plain Chocolate Candies were sold to the military as a convenient snack that traveled well in any climate. By the late 1940's, they became widely available to the public, who gave them an excellent reception. In 1948, the packaging changed from a tube form to the characteristic brown pouch known today.
