In the U.S., HBO is a very aggressive service.

I'm an HBO subscriber, and I watch a bunch of great shows on HBO.

I founded Netflix. I've built it steadily over 12 years now, first with DVD becoming profitable in 2002, a head-to-head ferocious battle with Blockbuster and evolving the company toward streaming.

Technological revolutions are very hard to predict. My favourite example is someone in 1850 taking care of horses as a farrier. They would have said, "Look, horses have been part of human existence for 5,000 years. We are horse people. It's permanent." But all of a sudden, the internal combustion engine comes along and, with it, oil fields and automobiles, which basically replace the horse completely. So we often have these long periods of stability and then a sudden inflection point.

But it may be one of our best markets in the long term because when the Japanese society embraces a brand it is a very deep connection, so we're willing to make that investment knowing that it's not the quick route to success that might be in other countries.

Interactivity and a better experience aren't always the same thing.

Don't be afraid to change the model.
