Have you seen some of the videos in the ‘Shows’ section of YouTube? Almost all of them have very few views and only 1 pre roll clip, so for a 30 (or even worse, 60) minute TV programme, they’re just about covering the cost of delivering the video.
I wouldn’t be surprised if Google have to re-brand the platform that delivers full length shows from the UGC site. (And maybe call it Hulu). YouTube simply isn’t an obvious destination for full length shows, despite every other London bus advertising the feature.
