National M&M Day

October 13th is National M&M Day – an opportunity to treat yourself and your loved ones to delicious M&M’s candies! The treat was first introduced in 1941 by Forrest M. Mars and Bruce Murrie, the son of the Hershey CEO. The name is an acronym for “Mars & Murrie.”

History

M&M’s have been a popular treat since they were first introduced. During World War II, they were included in military rations due to their convenience, as they did not melt in the hands. The famous “M” on the brand’s candies was introduced in the 1950s, followed by the slogan “Look for the letter ‘M’ on every candy.” Over the years, the range of M&M’s flavors has expanded significantly, including mini-M&M’s, peanut M&M’s, and many others.

Interesting facts
