Radio static has been a staple sound effect since early radio dramas and war films, where an untuned dial or failing field set signalled soldiers, spies or stranded characters cut off from help. As editing software became common, short static bursts were shared on soundboards and in meme packs as a ready made transition. Creators still reach for it today because the hiss is understood instantly, without any dialogue, and it can turn an ordinary cut into a moment of interference, surveillance or sudden disconnection.
