When CNN launched in the early 1980s, everybody said: A 24-hour news network won't work. They launched, they did ok, CNN went almost bankrupt because of the risks they had taken, they got bailed out, and 25 years later CNN is a huge global brand. I think the same is going to happen in digital. If you look at the younger generation, there is a huge consumption of digital media and almost no consumption of print or traditional television. Eventually money will follow that. It is just a question of which companies win, how long it takes to get there and what kind of model you need to apply.

Some people have made a fortune by being employed. Jerry Bruckheimer does not own his content. Warner Bros. owns his shows. They are on CBS, and he makes a fortune.

Wrapping rubber bands around a watermelon is not journalism. It is entertainment. But the key to success in media has always been a broad mix of serious reporting and entertainment. The New York Times does not make its money on reports about Iraq and Syria. It makes money on its gardening section, food and, yes, stories about cats. "The Today Show" is a very successful program because it is a mix of the celebrity chef and the crazy pet who does the rolls and serious news and interviews.

Pornography works to a degree, high quality works, bad is obvious. Nobody goes for bad. The terrible middle ground is the mediocre. That was kind of the essence, in a way, of broadcast television when there were only three channels.

I think the water cooler is more important than ever. "Oh, did you hear that 'Inside Amy Schumer' is fabulous?" Where do you find it? It's on Netflix, it's on iTunes, it's on places nobody ever heard of five years ago.

When television came in, everybody thought that was the end of the movie business, which was not and is not.

Successful publication is all about the mix. What Buzzfeed discovered was that people like cat pictures. We can pretend to be embarrassed about that as a species, but it is actually a truth. So Buzzfeed publishes a lot of cat pictures. But they use the money from cat pictures to build an exceptional newsroom that publishes stories that far fewer people want to read, but it is very important journalism.
