AIM (software)

AOL Instant Messenger (AIM, sometimes stylized as aim) was an instant messaging and presence information computer program created by AOL that operated from 1997 to 2017. It used the proprietary OSCAR instant messaging protocol and the TOC protocol to allow users to communicate in real time. AIM launched in May 1997 and became popular by the late 1990s; teens and college students were known to use the messenger's away message feature to keep in touch with friends, often frequently changing their away message throughout a day or leaving a message up with one's computer left on to inform buddies of their ongoings, location, parties, thoughts, or jokes. AIM's popularity declined during the 2000s and 2010s as AOL subscribers started decreasing and as Gmail's Google Talk, SMS, and Internet social networks like Facebook gained popularity. Its fall has often been compared with other once-popular Internet services, such as Myspace. In June 2015, AOL was acquired by Verizon Communications. In June 2017, Verizon combined AOL and Yahoo into its subsidiary Oath Inc. (now called Yahoo). The company discontinued AIM as a service on December 15, 2017.
