A few years ago the UK was well ahead of the US in the availability of streaming video. Now, the UK is way behind, with no serious public PPV service to compete with Hulu, Amazon et al in the US.
Much of this is down to the fact that so many rights in the UK are controlled by Sky, who are determined to build their walled gardens ever higher. Since Sky is fundamentally a pay to view company, you can't blame them, but they really are stymieing choice in the UK market.
And none of the other broadcasters can afford to take them on - they're running rings around Virgin Media, whose debts continue to rise, and the other broadcasters need them too much.
When it comes to customer choice, OFCOM is once again behind the times.
