ICQ launched in 1996 as one of the first popular instant messengers, and its short message alert quickly became shorthand for being online. As users moved to newer apps, the chime survived in memory, shared clips and retro internet compilations, where it instantly evokes dial-up era chat rooms and desktop computers. Today creators reuse it less as a functional notification and more as a cultural cue, signalling nostalgia, an old-school conversation or a message arriving at the worst possible moment.
