Google has - at least at this point - maintained the line where it keeps organic results separate from the advertisements. But over time - so in other words, you still get the - there still are honest to goodness results which are based on an algorithm which is based on how important or how many people link to that particular site, so there's that. At the very beginning, there were unobtrusive advertisements on the side that sort of showed up when you typed in certain phrases. Over time, the amount of real estate that those ads take up has increased.

Facebook, when it began, like Google, was very resistant to advertising. They knew, like all - Mark Zuckerberg, like all good engineers, knew that advertising makes the product worse. But, you know, over time, they've been forced to increase the advertising load more and more and more. And the way they advertise is they - it's subtle but they know everything, you know, about everybody on the site.

There is this inherent human instinct that the usual way you control trolling is you force people to use their real identities. So there's less trolling on Facebook, for example.

More than anyone else, Adolf Hitler completely understood the union between government propaganda and between - and advertising, that they were in some ways the same thing.

Hitler understood the demagogues' essential principle to teach or persuade is far more difficult than to stir emotion.

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.

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.
