The sound comes from the default sound scheme of Microsoft Windows 98, released in 1998, where Notify was assigned to system notification events. It was heard on millions of home and office PCs, alongside startup and error sounds that defined that era of personal computing. As clips and remixes moved to YouTube and soundboards, the chime survived as a shorthand for old computers. It now sits alongside the modern Discord notification and a simple ding sound effect, but its softer, rounder tone keeps it instantly tied to late nineties desktops.
