It became a vital part of a US soldiers' diet during World War II - and now it's sold in 48 countries around the world. Spam, stylised as SPAM, was created by Hormel Foods Corporation in 1937 to increase the sale of pork shoulder, a cut which did not sell well.
Ken Daigneau, brother of a Hormel Foods vice president, won a contest - and $100 - for naming the SPAM brand - but ever since then, people have been wondering what the 'acronym' actually stand for. Taking to Reddit, one confused user asked: "What does the acronym SPAM (meat) mean to you?"
In response, one user said: "Shoulder Pork and Meat." Another user added: "Spare Parts of Animal Meat... At least that's what us kids called it." A third user said: "Salted Pork Aggregated Meat."
