Re: Who's competing with what, exactly?
Boy what a load of rubbish.
Firstly unless there is some way to start compition then you will only ever have one or two Big Ones, its the cahnges that wre made to how premier league football was bid for that led to others apart from Sky having some and we having some compitition on it. The same is true for everything else, don't forget for years Sky had the streming rights on most movies in this country and never used them which is why we have so little on Netflix or Amazon compared to the USA.
Secondly Sky are not the only broadcast service. TalkTalk and BT carry it over DSL and Virgin over their network. This is the same exactly as Sky just with wires / fibre. Add to that Netflix etc who you quote are purely stream on demand and not live broadcast then they are not part of the same system
What is needed is for Sky to be broken up the same as BT, Openreach was split off and must treat everyon equally, Sky subscription channels should be the same, a seperate company selling to Sky TV, BT etc on an equal footing. Then we would have real compitition with any company able to offer everything to customers and compete to get out business.
