LINE launched in 2011 and became one of the most widely used messaging apps across Japan, Taiwan, Thailand and other parts of Asia, known for its free voice and video calls. Its incoming call tone became instantly familiar to millions of users who heard it daily. As short-form video and soundboards grew, creators lifted the ringtone to stage fake calls, phone prank scenes and realistic chat recreations online. The clip remains popular because the ringing is recognisable even without the app on screen, so audiences understand the joke or situation immediately.
