Little is documented about the original source of this clip, and it is best understood as a short soundboard effect rather than a line from a film, show or game. The title points to FM radio and online media, two places where short stingers, transitions and notification-style effects are used to signal a change of segment or grab attention. On soundboards it sits alongside other broadcast-style effects, and creators reuse it because it is compact, instantly recognisable as media-related and easy to drop into intros, streams and edits without needing dialogue or music.
