Skype launched in 2003 and became the dominant free video calling app of the late 2000s, with its cheerful incoming call chime heard in homes and offices worldwide. After Microsoft acquired Skype in 2011, the sound remained the app's audio signature for years. As usage declined, the ringtone lived on as internet nostalgia, sampled in prank videos, reaction edits and retro tech compilations. It is often paired with the Discord call ringtone or the Discord notification sound in edits comparing old and new eras of online chat.
