MSN Messenger launched in 1999 as Microsoft's instant messaging service and later became Windows Live Messenger before most users were moved to Skype in 2013. Its default alerts, including this short new message chime, were heard daily in homes, schools and internet cafes during the service's peak in the 2000s. As the platform faded, recordings of its interface sounds circulated on soundboards and in nostalgia edits. The chime remains popular because it instantly dates a scene to early social internet culture and is understood even by viewers who never used MSN themselves.
