The History of M&M's: From Wartime Candy to Global Icon

The history of M&M's in brief

M&M's are small, round, coated chocolate buttons created by Forrest Mars Sr. and Bruce Murrie in the early 1940s. The candy launched in the United States in 1940 as a ration‑friendly chocolate that would not melt in a soldier's pocket. The name comes from the surnames of Mars and Murrie. Over time, M&M's evolved in color, packaging, and marketing while becoming a globally recognized treat. This profile explains the origins, product development, and enduring appeal of M&M's with verified details and timeline highlights.

Origins and wartime purpose

Forrest Mars Sr., son of the Mars company founder, observed British soldiers eating small, hard chocolate pellets during the Spanish Civil War in the 1930s. He partnered with Bruce Murrie, son of a Hershey executive, to create a similar product. They secured a patent for a process that placed a colored shell around a chocolate center. The candies were designed to be heat‑resistant, practical for soldiers in warm climates. In 1940, M&M's were introduced in the United States expressly as a military ration chocolate sold in cardboard tubes.

Postwar expansion and color evolution

After World War II, M&M's transitioned to civilian markets and were sold in cardboard packaging featuring the now‑familiar "m" logo. In 1954, the brand introduced the tagline "Melts in your mouth, not in your hand" to emphasize the heat‑resistant shell. For decades, M&M's were produced in a limited palette. In 1995, the company added a new color through a public vote, and blue joined the original red, yellow, green, and brown (orange was added later, in 2000). The color choices have periodically been adjusted for special editions, but the standard set reflects decades of brand consistency.

Branding, packaging, and slogans

M&M's distinctive packaging and advertising have played a central role in its longevity. The animated characters Red and Yellow, introduced in the 1990s, became recognizable mascots in global campaigns. The brand has run long‑running slogans that emphasize the candy's melt‑resistant shell and the fun of the colorful assortment. Over time, M&M's expanded into larger sharing bags, seasonal variations, and flavor variants, while maintaining the core product concept of a chocolate button with a hard, colored coating.
