Windows 95 launched in August 1995, and its startup sound was composed by ambient musician Brian Eno after Microsoft asked for a short, inspiring piece. Eno famously made a version just over three seconds long, built from soft electronic tones that matched the system's clean new interface. The chime became one of the most recognised computer sounds of the decade. Online it survives through nostalgia posts, emulator videos and memes where the melody instantly marks a machine, idea or person as charmingly outdated but fondly remembered.
