ICQ was one of the first widely used instant messaging services, reaching huge popularity in the late 1990s and early 2000s before later versions like the 2008 client kept its familiar alerts. As messaging moved to phones and social apps, the old chimes survived on soundboards, nostalgia videos and retro internet compilations, where they instantly signal a simpler era of desktop chatting. Today creators pair the alert with keyboard typing and on-screen chat bubbles to recreate that period, keeping it alive as shorthand for early online friendship and humour.
