The best-selling chocolate treat on our list has been around since 1941 and was designed by Forrest Mars Sr. so consumers could enjoy their chocolate without having it melt in their hands. M&Ms, which was named after its inventors Forrest Mars and R. Bruce Murrie, were served to GIs serving in World War II and went on its first space mission in 1982. M&Ms are red, yellow, blue, orange and green, but it's red that gets top billing — it has been the official "spokescandy" since 1952. There are now eight permanent varieties of M&Ms candies, as well as seasonal offerings.
