Unsolicited commercial advertising. Spamming is against the TOS of almost every Usenet Access Provider. The USENET can take credit for being the first online medium to experience the phenomenon so many of us now hate. Supposedly, in 1993, Joel Furr, a USENET newsgroup administrator coined the term "spam" when he discovered that a piece or experimental software had released dozens of recursive messages onto the popular news.admin.policy newsgroup. The term was supposedly inspired by a 1970 Monty Python sketch.
