Apparantly at launch and for some time after, the only way to view this service on your big TV is via Chromcast and Mirrocast type via Chrome (I think) and mobile. There will definatley be NO access via connected devices to your big TV like Roku, SonyPlay Station, Amazon Fire, etc. for some time. But YT expects to make connected devices to big TV a realality some time in the future, but they didn't say WHEN. So, with the exception of Chromecast and Mirrorcasting, this is pretty much a PC or mobile device screen service (of course, its YouTube) for the time being and this limitation keeps quite a few non-techy folks OUT of the preferred way--and sometimes ONLY way people know how--to get content to their big TV, which is using their Roku, FireTV, etc. for all such services and who believe using Chromecast is far too much trouble, complicated, etc. These people really exist. For power users on this forum, Chromecast is laughably easy, but I'm telling you, MOST people don't want to go to what they consider to be "trouble" and "complication" and "another thingy hooked up to may TV!! Why can't I watch it on my Roku or Fire like I do everything else (meaning Netflix and Hulu, SlingTV, DirecTV NOW, etc.)?" "Nevermind, I'll just keep my cable and sat subscription until it is easy for me to watch, and when they get channels I want they don't have now." That's how the majority of the consumers view all this new-fangled technology and the "trouble" to get YT's new OTT service on a nice, big, HD or UHD TV because, "I aint a watchin it on no small PC screen or my phone." They want something like the Channel Master DVR+: a box (Roku, etc. count) to connect to the big TV and start a watchin' or an app they can launch from the Roku or Fire or the like.
