The sound comes from The Voice, the singing competition format that began in the Netherlands in 2010 and spread to versions around the world. Its blind audition stage made the red button and turning chair its most recognisable mechanic, with coaches pressing to claim a singer they have only heard. Clips of that moment were widely shared online, and the buzzer became a standalone shorthand for approval long after the auditions. Editors now reuse it outside the show whenever a choice needs instant, televised weight.
