Acronym for AOL Instant Messenger

A technology developed at AmericaOnline, it is an instant messaging service that allows you to chat online IRT with another user. It can be done either on your computer or via a wireless device, and there are no longdistance charges. It is considered an extremely "sticky" application; in fact, it's been measured that more than half of the time AOL users spend online is consumed by IM.
