“Gangnam Style” was released by South Korean artist PSY in July 2012. Its music video, distinctive choreography, and satirical portrayal of luxury culture helped it spread internationally through video sharing, parodies, reaction clips, and public dance performances. In December 2012, the official video became the first YouTube upload to reach one billion views. The shouted hook remains widely used because it is recognizable almost immediately, works in extremely short edits, and evokes the early-2010s wave of globally viral music videos.
