I think there will be 20 years of evolution from linear broadcast to internet television.

Interactivity is a big part of video games, which have been a big part of entertainment for 20 years. That's what we think of as a 'lean-forward' type of entertainment. It's much more intense. But TV is more of a 'lean-back' entertainment - so the big improvement there is on-demand, because it conforms to your schedule.

Not every show has to work equally well. It just has to work better than any competitor because then we can outbid for the content.

Fibre optic is becoming like electricity. If you look at how electricity spread around the globe 100 years ago, that's what's happening now.

In fact, technology has been the story of human progress from as long back as we know. In 100 years people will look back on now and say, 'That was the Internet Age.' And computers will be seen as a mere ingredient to the Internet Age.

About half my work in education is U.S. political reform around school districts and charter schools, and creating more room for entrepreneurial organizations to develop. And about half on technology, which I look at as a global platform.

I learned the value of focus. I learned it is better to do one product well than two products in a mediocre way.
