When they finish the process of better and better targeted advertising, that’s when the whole idea of advertising will go poof, will disappear. If it’s perfectly targeted, it isn’t advertising, it’s information. Information is welcome, advertising is offensive. Who wants to pay to create information that’s discarded? Who wants to pay to be a nuisance? Wouldn’t it be better to pay to get the information to the people who want it? Are you afraid no one wants your information? Then maybe you’d better do some research and make a product that people actually want to know about.
