Low viewership is because the app on the samsungs is a laggy piece of crap, on the PS3 it seldom works, and who wants to watch on a phone without the ability to cast to a larger screen.
Android app wont work on a set top box because of their paranoia over rooting and HDMI output. So that leaves hulu/BBC iplayer/itv etc as the ideal source for that same content. Which they will never see the use of so think there is no demand.
Cant expect demand when the platform is so crap at the moment. Apple TV box would let them have it nativly on a TV without their fear of android and HDMI out getting in the way.
Last month - 5,834,455 streams. Average duration 28 minutes. So your views on demand (and lack therefore) are baseless.
