M&MÂ®/Mars, the company that currently manufactures M&MsÂ®, first manufactured the candies in 1940. Forrest Mars, Sr., who formed M&M Limited in Newark, New Jersey, wanted to sell chocolates that could be sold year round, especially during the summer months when sales traditionally decreased. Since air conditioning was not available, retailers did not have the means to keep chocolate from melting and consumers did not buy it. By putting his chocolate inside the candy shell, the chocolate did not melt and M&Ms3 could be sold any time. They could be eaten neatly in almost any climate. In fact, they were made part of service rations during World War II.
