As per this BBC news article, 3rd May 2008 is the 30th Anniversary of email SPAM. The first spam message was sent to 400 users on the ARPANET by a DEC employee on 3rd May 1978. But, this was not yet the beginning of the commercial SPAM era. It was only in April 1994 when a group of immigration lawyers sent the first commercial spam message to more than 6000 USENET discussion groups thus,spawning a new rogue business model using the internet.
