New landmark for online video crossed as PSY's "Gangnam Style" becomes the first video to be viewed more than 1 billion times on YouTube, the world's largest video sharing site.

A new landmark for online video was crossed this afternoon, as the music video for PSY's "Gangnam Style" became the first video to be viewed more than 1 billion times on YouTube, the world's largest video sharing site.

The billionth view came just 159 days after the video was first uploaded on 15th July this year, capping off a remarkable year for the Korean pop superstar.

Along the way to the billion viewer mark, Psy has also earned two other Guinness World Records achievements; most watched video online, and most "liked" video online.

Record-breaking success has been a long time coming for PSY (real name: Park Jae-sang) - while "Gangnam Style" may be the first many of us in the west will have heard of him, the single actually comes from his 6th studio album and 11 years after the release of his debut, "PSY from the PSYcho World!" in his native South Korea.

One billion views of the catchy 4 minute, 13 second song is equivalent to 8017 years of total viewing time, or around 119 human lifetimes.
