Why Every M&M’s Candy Is Stamped With A Little ‘M’
Mars Inc. introduced the trademark detail in 1950 to distinguish real-deal M&M’s from imitations. The M&M’s name references the initials of the chocolate company’s two co-founders, Forrest Mars Sr. and Bruce Murrie (both the sons of chocolate company executives). Mars bought out Murrie’s share of the company in 1946, four years before the stamp was introduced, which means we can safely assume the “m” stands for Mars.
