YouTube has announced that its users upload 60 hours of footage per minute and watch 4bn videos each day.

Aside from being an impressive milestone, the statistic will be a useful sales tool for the video site as it seeks to bring in more advertising revenue following its recent redesign.

Experian also revealed that YouTube accounts for 25% of visits to social sites in December, second only to Facebook.

Following its revamp to focus on channels YouTube has been looking to bring in new partners who can provide original content – something that is particularly appealing to advertisers and sponsors.

Last week it announced the launch of Reuters TV, a new channel that will supply original news content – with ITN also staking it’s claim.

So this latest milestone comes at an important time for YouTube as it goes head-to-head with the likes of Netflix and LoveFilm for online audiences.
