Although many have long believed the initials of M&M's simply stand for 'Mmm', as in the noise of pleasure you make when you eat them, this isn't actually the case. The popular chocolate has in fact got a pretty interesting history behind it, and was created thanks to family rows.
First invented in the US back in 1941 as a small, easily transportable snack for soldiers, inspiration struck in the 1930s when co-founder Forrest Mars Sr. reportedly encountered British volunteers eating small chocolate beads with hard sugar shell casings to stop them from melting.
The son of Mars Incorporated founder Frank C. Mars, Forrest had been expected to take over the family firm but moved out to England after a row with his father. After moving back to the US to take up his position in his father’s company, Forrest secured a patent for the production of his chocolates, and, displeased with his father's way of doing business, sought a like-minded partner to bring his delicious idea to life.
