YouTube is to run a trial of "pre-roll" video ads on selected content from several broadcasters starting from today. The pre-roll ads are short video ads shown before the video you requested and could be up to 30 seconds long. Advertisements will start appearing around videos from BBC Worldwide, ITN, Discovery, National Geographic and – from today – Channel 4.
