AOL Instant Messenger (AIM) was a transformative platform for online communication during the late 1990s and early 2000s, becoming a cultural phenomenon despite initial skepticism from AOL executives. It gained popularity as a means for users to connect with friends and express themselves through quirky screen names and away messages. AIM faced challenges in monetization and adapting its business model but left a significant mark on internet history. Its decline was influenced by the rise of social networks and mobile messaging apps. The story of AIM's impact is discussed in a recent episode of the Version History podcast.
