Re: Which country?
Ever watched an episode of The Sopranos?
Not me. I know the lead character is called Tony and I know the spoiler for how the final series ends. Game of Thrones might have been a better reference, though I've not watched that either.
I know "HBO"; it pops-up at the end of some programmes shown on UK channels. As to what "HBO" is beyond "Home Box Office"; I'm not sure, but I'm guessing it's more than a production company. I don't know what "Hulu" is either and I have had no interest in finding out because last I heard it still wasn't available in the UK.
I have a Virgin Media TiVo which supports iPlayer and other catch-up services, subscription free Sky, Freeview, Freesat, Chromecast, a PC desktop, a huge DVD collection, and an Android TV box in a drawer somewhere, so I haven't felt the need for subscription streaming services. I'm also guessing anything decent will eventually find its way to DVD, then into CeX and charity shops so I will eventually get to see it.
