Psy's 'Gangnam Style' makes YouTube history

South Korean pop artist Psy and his "Gangnam Style" video marked a historic milestone Friday, becoming the first YouTube video to receive one billion views. The video was posted on the site in July.

Psy raps in Korean in the video while dancing as if riding an invisible horse.

Psy, who is 34, is the first Korean pop artist to receive mainstream success in the United States.

He won the best video award at the MTV Europe Music Awards in November.
