AOL's AIM introduced an early AI chatbot and reached 36 million users in 2001. The platform struggled to adapt to the rise of mobile communication, leading to its shutdown on December 15, 2017. AIM popularized personal screen names, emojis, and status markers in instant messaging, and it influenced figures like Biz Stone and Mark Zuckerberg. AIM's legacy continues to impact modern messaging, which incorporates various multimedia elements.
