ICQ launched in 1996 from the Israeli company Mirabilis and became one of the first mainstream instant messengers, later acquired by AOL in 1998. Its library of short notification sounds, including the authorization chime heard here, defined the audio language of early online chat. Long after the service faded, clips from its sound set circulate as nostalgia memes and retro-tech jokes, often appearing in compilations alongside Discord's notification and other messenger alerts that replaced it.
