UK-based YouTubers can now earn ad revenue from posting videos to the UK site, as US users have been able to do since early last year. The UK version of the site is the first outside the US to benefit from the YouTube Partner Programme, with more European territories in the pipeline. Adverts run next to videos. Contributors retain their own copyright. Those in the UK set to benefit include GiR2007, a computer scientist whose most popular video ‘Pancakes’ has generated 2.5m clicks to date.
