MSN Messenger launched in 1999 as Microsoft's instant messaging service, and this alert belonged to its early versions used through 2001. As home internet and instant chat grew, the sound became tied to a generation's first online friendships and constant message checking. It later spread through soundboards, nostalgia videos and retro edits that recreate early 2000s computer life. Modern viewers often compare it to the Discord notification, another short alert that signals a new message, but the MSN chime carries a distinctly older, more personal nostalgia.
