YouTube adds ads but won't pay all content-makers

The company currently shares ad revenue with video-makers who are enrolled in its partnership scheme, when it shows ads before or during their content.

But YouTube says it will start putting ads on some videos from channels that are not part of its partnership scheme.

Changes to its terms of service mean YouTube will not share the revenue from those ads with the video-makers.

It could also mean viewers see a higher number of adverts across the site.
