MSN Messenger launched in 1999 and later became Windows Live Messenger before being retired in 2013 in favour of Skype. Its alert and nudge sounds were heard daily by millions of users during the peak of instant messaging. Clips of the chime now circulate in nostalgia edits and meme soundboards, where it works as shorthand for early 2000s internet culture. It is often compared to a modern Discord Notification or Discord Call sound, but its warmer electronic tone marks it as distinctly from the MSN era.
