America's Got Talent launched in 2006 as the US version of Simon Cowell's Got Talent format, where judges use buzzers to stop acts they dislike. Four red buzzers signal a unanimous rejection and light up giant red Xs above the stage. The short buzz became shorthand online far beyond talent shows, spreading through memes, classroom games and edit packs as the universal audio cue for you are out. Its link to televised elimination keeps it instantly recognisable in 2024 clips and compilations.
