Since it's launch five years ago, YouTube has revolutionised the way we use the internet.
From music videos, to how-tos and viral videos, YouTube has it all. On Sunday, the internet giant said that the number of videos watched daily at the website has broken the two-billion mark as the service begins celebrating its fifth birthday.
"Thanks to you, our site has crossed another milestone and now exceeds over two billion views a day," YouTube team members said in a blog post. "That's nearly double the prime-time audience of all three major US television networks combined."
Here are the top ten most viewed videos of all time:
1. Lady Gaga - Bad Romance
