"Speaking as one who recently had US family to stay in London, who had never experienced Sky+ (or the freeview equivalent) and the plethora of OnDemand TV via the box in the corner and Tablet/Phone on-demand apps complete with Chromecast, they were blown away at what we could do in the UK compared with what they had available via Cable in the US."
Don't know where your friends from the US were/are from, but my cable operator here in the US has dozens of On Demand channels offered free, and hundreds of other channels...including a plethora of Pay-per-View channels...both included with your monthly fee, and many more for additional fees. Well over 600 channels to choose from.
Also, anyone who chooses to pay for the Google dongle can use it here. It's not an exclusive thing to the UK.
Besides, connecting any Internet connected device to an HDMI capable tele is not exactly rocket science these days.
So I'm afraid that the UK isn't alone in its available content. There is plenty to choose from on this side of The Pond as well.
