The TV business model is that customers pay for more than they consume. The bill keeps running while you're at work. The bill is the same if you go on vacation. It doesn't matter, because you pay in advance for more content than you can possibly ever consume.

That is the business model. That is the way it works. That you pay for shopping channels that you don't care for allows them to pay for expensive shows like Mad Men.

So what we need is real disruption in the TV business but that is not a new UI. It's a fundamental change in the way TV programming is financed.
