YouTube's top five most-viewed videos in the UK, as the site turns eight

Still from YouTube's most-watched video in the UK - 'Charlie bit my finger - again!'

It's hard to believe it, but it's internet giant YouTube's eighth birthday today.

The first video was uploaded onto the website on April 23 2005. Looking at the top ten most viewed videos (in the UK) on YouTube, it's hard to find a common trait or pattern other than a love of pop music and a penchant for the bizarre.

Adele features prominently in the most-viewed (from the UK) videos on YouTube of all time - with her songs "Rolling In The Deep" and "Someone Like You". One Direction are also in the most-viewed chart multiple times - with "What Makes You Beautiful", "Kiss You", "Little Things", and "Gotta Be You".

A strange entry at number four, but who ever said that the most popular things on the internet had to make sense?
