Michael Albers, vice president of communications product at Oath, made the announcement about the messaging platform on Tumblr . He cited changes in "the way in which we communicate with each other" as the reason for shutting down AIM, which has been around since the 1990s.He also thanked AIM users, saying they "likely remember the CD, your first screenname, your carefully curated away messages, and how you organized your buddy lists."Originally a part of the AOL Desktop internet suite, it became much more popular once it was split off into a separate download. At the time it was in competition with Microsoft's MSN Instant Messenger service, Yahoo! Messenger, and ICQ.AOL Instant Messenger is such a point of nostalgia for some that using the messaging service is the premise of indie game Emily Is Away.
