Word Origin:
[spam] 1930s: apparently from sp(iced h)am. The Internet sense appears to derive from a sketch by the British “Monty Python” comedy group, set in a cafe in which every item on the menu includes spam.

Culture:
Spam is made mainly from ham and was widely used to feed US soldiers during the ↑Second World War, when it also became popular in Britain. It is still popular in the US today but less so in Britain. The word is a shortened form of ‘spiced ham’. Because it is a simple and cheap food, people often make jokes about it and a Monty Python sketch was set in a cafe where every item on the menu included Spam. This may be the origin of the modern use of the word to mean unwanted emails.
