The golden buzzer was introduced on Britain's Got Talent in 2014, letting each judge and the hosts send one act per series straight through to the live semi-finals. Pressing it triggers the distinctive buzzer, cheering and golden confetti on stage. Clips of the moment spread widely on television highlights and social media, and the audio was later isolated as a reusable buzzer for edits. It remains popular because viewers instantly recognise the format and understand that something exceptional has just happened without needing any extra explanation or context at all.
