YouTube have been experimenting all different kinds of advertising in their videos. Over the ad, next to the ad, during the ad, before the ad - they've tried it all.
I've previously said that I thought that YouTube would lose people if they put pre-roll ads onto their site. YouTube seem to have agreed, as they stopped testing them. But they are back with new pre-roll testing, however this time it will be skippable with a "No thank you" link. I think that this is far more likely to survive, as it has on other file sending sites, such as zshare and relay it. Maybe they've found a happy medium here? I still think that relevant ads alongside content are the way to go. Make them highly relevant and of a high standard and people are more likely to be interested and less likely to be annoyed.
