MSN Messenger was Microsoft's popular instant messaging service in the late 1990s and 2000s, where friends chatted in real time, used emoticons and nudges, and showed their status to contacts. Its familiar chat window became a symbol of early social internet culture, long before modern messaging apps took over. Short sounds linked to that era, like rapid typing, are now reused in memes and throwback videos because they instantly signal an old-school online conversation. Even though the service closed in 2013, its look and sounds remain widely recognised online.
