Microsoft commissioned ambient musician Brian Eno to create the startup music for Windows 95, released in 1995. Eno produced a short, ethereal piece about three seconds long that became one of the most recognisable computer sounds of the decade as millions of PCs played it daily. As Windows 95 faded from everyday use, the chime survived online through nostalgia videos, retro computing communities and meme edits. It is now reused whenever creators want an instant reference to 1990s technology, early internet culture and childhood computer memories.
