On Twitch, following a channel is the basic way viewers keep up with a streamer, and a follow alert has become a familiar part of that live experience. Streamers display the follower's name on screen and play a short sound to acknowledge the support in real time, turning an otherwise silent action into a visible celebration. The format spread through stream highlights, clips and edited compilations, where the same chime signals growth, community and momentum. It remains popular because it is instantly recognisable to anyone who watches live streams.
