Static interference has been familiar since the early days of analogue television and radio, when an untuned set filled the screen with snow and the speakers with hiss. As broadcasting moved digital, that sound survived as a universal shorthand for a signal gone wrong. Editors, game designers and meme creators adopted it for VHS rewinds, found-footage horror, fake livestream dropouts and retro technology scenes. Because almost everyone recognises it instantly, a second of static can reset a scene, hide a cut or sell a technical failure without any explanation.
