The sound is based on the notification tone from WhatsApp, the messaging app whose short message alert became familiar to millions of phone users around the world. As the tone became part of everyday phone life, louder boosted edits began circulating on soundboards and in short-form videos, where creators wanted the same recognisable ding to stand out over music and speech. Its popularity in prank and meme content comes from that instant recognition, since listeners immediately associate it with an incoming message even when no phone is on screen.
