The phrase comes from decades of radio and television broadcasting, where announcers used it to signal a pause for paid advertising. As video editing and meme culture grew, creators lifted the familiar transition out of its original context and began using it ironically, especially to introduce invented products or mock sponsorships. Its recognisability is the point: listeners instantly understand the format being parodied, even without any visual cue. That shared familiarity keeps it useful for comedy, commentary and short-form videos today.
