What it was
AOL's standalone instant-messaging service, known for screen names, buddy lists and away messages.
AIM turned the desktop into a social place long before feeds and smartphones dominated online life. It launched publicly, reached mass use, outlived AOL's dial-up peak and accumulated two decades of personal language and memory.
Existence timeline

Buddy lists and away messages become everyday social infrastructure.
AOL tells users the service will close after twenty years.
Official AIM sign-in and messaging end.
AIM's standalone network and familiar presence tools become a mass-market social layer.
Why it ended
Oath, AOL's then-parent company, retired AIM on December 15, 2017 as communication habits shifted to mobile and social platforms.
Last confirmed trace
Client installers, screenshots, protocol documentation, fan servers and personal archives preserve pieces of the experience, but the official network no longer operates.
What it left behind
Its status indicators, direct messages, screen-name culture and lightweight presence model became standard features of later online communication.
