Claire Cain Miller for the New York Times Bits Blog:

On Wednesday, [YouTube] introduced a new kind of ad for its mobile site that lets viewers choose whether or not to watch a video ad, and only charges advertisers if the ad is watched.

Finally, YouTube offers ads on mobile. Wait, what’s that?

The new type of ad joins other ads that YouTube offers for its mobile site, including banner ads shrunk for the mobile screen and promoted videos that show up in YouTube search results.

Nice. More shit between you and that video you were looking for.
