Spam (stylized as SPAM) is a brand of processed canned pork and ham made by Hormel Foods Corporation. It was introduced in 1937 and gained popularity worldwide after its use during World War II. By 2003, Spam was sold in 41 countries (and trademarked in over 100) on six continents.
Spam's main ingredients are pork shoulder and ham, with salt, water, modified potato starch (as a binder), sugar, and sodium nitrite (as a preservative). Natural gelatin is formed during cooking in its tins on the production line. It is available in different flavours, some using different meats, as well as in “lite” and lower-sodium versions. Spam is precooked, making it safe to consume straight from the can, but it is often cooked further for taste.
Concerns about Spam's nutritional attributes have been raised due to the fact that it contains twice as much of the daily dietary recommendation of fat as it does of protein, and about the health effects of salt and preservatives.
Spam has become part of popular culture, including a Monty Python sketch, which repeated the name many times, leading to its name being borrowed to describe unsolicited electronic messages, especially email. It is occasionally celebrated in festivals such as Austin's Spamarama.
