ICQ launched in 1996 as one of the first widely used instant messaging services, letting users keep a contact list and see in real time when friends signed in. Its short system sounds became part of everyday computer use for millions of people in the late 1990s and early 2000s, and the online alert is now remembered as a shorthand for that era. Creators reuse it today in throwback edits and reaction videos because the single chime instantly suggests old-school messaging, even for viewers who never used the original program.

The short ICQ alert chime from the classic 1990s messaging app, used when a contact signs in and in nostalgic videos, streams and retro edits.
The ICQ online sound is a brief, bright electronic chime lasting just over a second, with a clean digital tone that instantly signals someone has just appeared online. It carries the unmistakable feel of late 1990s desktop messaging, when a friend logging in felt like a small event in itself. In a modern video it works as a quick punch of nostalgia, making viewers smile at the memory of blinking contact lists, slow connections and waiting for a reply, while also clearly marking the moment a character, friend or notification arrives on screen.
