The horse-dancing video by Korean pop star Psy has become the first video on YouTube to top 1 billion views.
Psy’s “Gangnam Style” video reached the milestone on December 21, and at the time of writing stood at 1,046,274,259 views.
The song, featuring Psy’s horse-riding dance moves, reached the historic milestone 27 days after overtaking Justin Bieber’s “Baby” video as the most viewed clip on the website.
Psy topped Bieber’s 803 million views and ploughed on at 76.4 views per second to achieve the billion mark.
By comparsion, “Baby” is proceeding at about three views per second.
The website Billboard.com estimates that “Gangnam Style” has generated $US2 million in advertising revenue from YouTube and nearly $US4 million from digital downloads.
The song was released five months ago.
Psy, 34, whose real name is Park Jae Sang, has been touring the globe on the back of his “Gangnam Style” success.
Gangnam Style last month became the first Korean song to top Britain’s official pop chart.
Psy’s horse-dance moves have spawned hundreds of parodies.
YouTube noted in its trending blog: “It’s been a massive hit at a global level unlike anything we’ve ever seen before.”
Gangnam Style, the title of both the song and the album, is named after the affluent Gangnam District in Seoul.
Psy revealed earlier this month it took him 30 nights to perfect the dance.
He tried and rejected elephant, monkey and kangaroo moves. Even slithering snake manoeuvres got a try-out.
He finally decided that his horse moves were the answer, he said in an address to the Oxford Union debating society.
Online music magazine NME reported Psy as saying: “I tried every creature: elephant, monkey, kangaroo, snake. The kangaroo hopping was too slow, so we ended up imitating a horse.”
Psy explained he invented the dance featured in the video after being offered a spot dancing on a television show.
“I was so desperate to get noticed I went to a TV production company in Korea and started doing a dance – a crazy dance – up and down the corridors,” he said.
