Socialization would be the most successful thing to bring mainstream audiences to online computers.

In fact, the big steps forward for advertising, especially after World War I were when government just began employing the tools of advertising for its own purposes to get people to join the army and other things.

Starting with radio, starting with television, we got used to this idea of stuff being free as long as you just watch a few ads.

You have to think back to the '90s. The computer was this terrible-looking thing that was trying to compete with the television. And it was this idea of email and chat rooms and this kind of stuff that first people - got people there.

There's always going to be a tradeoff between trolling and anonymity, and I guess that's the way life will be. And you can manage it, but you can't cure it.

I think, by this point, almost everything on YouTube has some ad or another.

I think Google is the most successful attention merchant - profitable attention merchant in the history of the world, most successful advertising-only based company - most profitable. They started a very idealistic, beautiful company in many ways, but they didn't have a business model.
