South Korean rapper PSY's Gangnam Style has become the first video to have over one billion views on YouTube
It has inspired hundreds of parody clips, from members of the British army, Thai navy and Minecraft gamers, among others, the BBC reports.
According to the report, 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, Justin Bieber's music video Baby, on 24 November, the report said.
"PSY's success is a great testament to the universal appeal of catchy music - and er, great equine dance moves," wrote Kevin Allocca, YouTube trends manager, on the service's blog.
