Microsoft launched Windows 95 in August 1995, and its short startup sound was composed by musician Brian Eno, who was asked to create something welcoming, optimistic and futuristic for the new system. The chime played every time the operating system loaded, so millions of home and office users heard it daily throughout the late 1990s. As Windows moved on, the sound survived through retro computing channels, nostalgia videos and meme edits, where it now instantly signals the mid-nineties era of personal computing.
