Microsoft released Windows 95 in 1995, and its startup sound was composed by musician Brian Eno, who created a brief, optimistic chime to welcome users to the new system. The sound became familiar to millions as home computers spread through the late 1990s, and it later survived as a cultural shorthand for that era. Online, creators revived it in retro tech videos, memes, and edits about old PCs, dial-up, and early internet life. It endures because a few seconds instantly place viewers back in the mid-1990s.
