Gangnam Style hits one billion views on YouTube

South Korean rapper Psy's hit song 'Gangnam Style' has become the first video to clock up more than one billion views on Youtube.

The South Korean dance track was posted online in July, propelling pop star Psy to worldwide fame.

The video was posted in late July and started taking off in August and by September, at which point it was being seen 7-10 million times a day, and up to 12 million on Saturdays.

It has inspired hundreds of parody clips from members of the British army and Thai navy among others.

Youtube's owner Google said the video had been watched seven million to 10 million times a day on average.

It overtook the previous record holder- teen pop star Justin Bieber's music video 'Baby'.

"Psy's success is a great testament to the universal appeal of catchy music and, great equine dance moves," Youtube trends manager Kevin Allocca wrote on the service's blog.

It has inspired hundreds of parody clips, from members of the British army, Thai navy and Minecraft gamers, among others.

One industry watcher said the fact so many people continued to post their own versions of Gangnam Style had played a huge part in the clip's success.

"I've seen a statistic which reckons the one song will have generated something like $8m [£5m] by the end of the year from money that comes directly from YouTube through advertising plus download sales, its uses in adverts and TV programmes,"
