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.
Tim WuHitler had this understanding that you speak to people's deepest, darkest emotions and give them voice that can be incredibly effective.
Tim WuGoogle has you at a very specific mental state that is, looking for something. And what they've always been able to say is, we deliver your message at the exact time someone is, say, looking for fishing hooks or looking for marriage counseling or looking for a lawyer for a particular problem. And here we have our customers telling you what is in their heart and soul. It's something that, you know, advertisers have wanted for decades.
Tim WuGoogle's AdWords, they allow you to bid on words that people will type into the search engine, and they cost more or less. For example, I think mortgage refinancing can cost - now, it's probably hundreds, maybe thousands of dollars. So, in other words, they are allowing you to bid on what people are going to type, and that is the AdWords program. So you own certain terms, and then your ads show up as opposed to someone else's.
