MSN Messenger launched in 1999 as Microsoft's instant messaging service and became a default after-school chat tool through the 2000s, with its soft alert signalling a new message. As smartphones replaced desktop messengers the service closed in 2013, but the ding survived in nostalgia edits, soundboards and meme videos alongside other period PC sounds like Windows XP error music. It remains popular because a single chime instantly dates a scene to early internet culture and signals a message arriving without needing any on-screen explanation at all.
