Psy's Gangnam Style — a Seoul satire that became the first 1-billion-view video

In July 2012, South Korean rapper Psy posted a music video for 'Gangnam Style', a song about Gangnam, Seoul's ritziest district. The joke was the 'Gangnam man' — someone who dresses classy and dances cheesy, chasing an image of wealth. Psy turned that satire into a dance where the rider of an invisible horse keeps a perfectly serious face; the more absurd the backdrop — elevator, parking lot, stable — the funnier the pose.

The video became a loop-first global meme: within months it was the most-viewed video on YouTube, overtaking Justin Bieber's 'Baby' in November 2012, and in December 2012 it became the first video ever to pass one billion views, still being watched seven to ten million times a day. Guinness World Records certified it as the most-liked video online.

No export strategy launched it. Psy told interviewers the concept was 'dress classy and dance cheesy' and that the move should feel like riding an invisible horse in your lower body. The song's success showed that a local satire, readable without knowing Korean, could carry Korean pop to the centre of global culture.

The transferable idea: a meme is a self-propelling ad when the joke fits in one frame and the dance can be imitated by anyone — the audience's remixes do the distribution a label could never buy.
