CBS was very generous in their offer to re-sign me. But I simply want to try something new.

I'm not the kind of guy who dabbles in a lot of things.

Cultures are not very easy to change. They're sometimes almost impossible to change.

My prediction is that in the same way that Google is an intent revealing service that can be monetized that way, I would think that if I were at Twitter, I would focus on the search aspect of Twitter, because people are revealing intents when they do a search.

On the Facebook side, I think it's a bit of an evolution, in that that company, which has clearly done amazing things, was, I believe, as an outsider looking in, was founded on a culture that was obsessive about the users. And they built a service that is very valuable for users, and that is to be applauded.

There's certain things like scripted dramas that - they're either topical or such water-cooler moments that I think that they'll be consumed within 48 hours. You don't have to consume them at 9:00 at night, but you want to consume them within the first couple of days so that you can talk to your friends about it.

I'm a big believer that media is an impulse business.
