Trolling is an ancient problem. It's been around as long as there has been media.

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

Every time you click on a like button on another site, you've told Facebook that you're doing that. And so therefore advertisers know who their fan base is.

History shows a typical progression of information technologies: from somebody's hobby to somebody's industry; from jury-rigged contraption to slick production marvel; from a freely accessible channel to one strictly controlled by a single corporation or cartel-from open to closed system.

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.

We already have our phones, but other wearables, and those technologies are going to want to know when you're deciding things and then offer some kind of input subtle or less so on that moment.

The Holy Grail of advertising has always been advertisement that people want to watch, which occasionally happens. You know, the Super Bowl, people sit there and watch the advertisements. Some print advertising is very beautiful.
