Our 100+ year history has a rich timeline. New products and services, new business segments and thousands of new Associates, but one thing remains: We’re still a family business at heart. You’ve been enjoying Mars products and services for years, and we’d like to share with you a little about who we are and where we came from. M&M'S had become so popular by 1950 that an ingenious solution for consumers to distinguish the real M&M'S from inferior imitators was to stamp each candy with the now famous "m". The slogan "Look for the m on every piece" was created.M&M'S Peanut Chocolate Candies were introduced in 1954 and the color used to print the "m" on M&M'S Plain and Peanut Chocolate Candies was changed from black to white.
