Discord is a chat and voice platform launched in 2015 that grew from gaming communities into a mainstream place for friends, creators and servers to talk. Its message ping, often shared as a Discord Notification, became instantly recognisable because millions of people hear it every day in direct messages and group chats. Editors began lifting it into short videos, streams and memes to signal a reply without showing a full screen, and its clean, neutral tone made it easy to reuse across jokes, pranks and reaction clips. It remains popular because the sound alone tells viewers a conversation has moved.
