This clip comes from the user-generated soundboard tradition rather than a named film, game or television show, so no single original broadcast can be confidently credited for it. Its name points to its job on a stream: marking subscriptions and donations, with a top-screen alert style familiar from live-stream overlays. As a short, reusable notification sound, it has circulated among creators who want a recognisable cue that does not need a licensed track or a long intro. That practical, plug-and-play use is why it keeps appearing in streams and edited clips.
