The phrase 'we'll be right back' comes from television broadcasting, where announcers have long used it to mark a commercial break or short pause without ending a programme. Online, editors borrowed that familiar cue for short-form video, using it to split a clip, hide a cut, or build anticipation before a reveal. Its spread was driven less by one viral video than by its instant recognisability: viewers immediately understand that something is about to return. That shared TV memory keeps it useful for streamers, editors and meme makers who want a quick, nostalgic transition.
