Introduction to targeted advertising

An AP article provides a simple introduction to targeted advertising. It underemphasizes targeting to the page content and overemphasizes privacy issues, but still a good introduction to the technique. I would have liked to see the article contrast this approach, which has the potential to make advertising useful and relevant, with the more common technique of exposing all your customers indiscriminately to annoying, intrusive, and mostly irrelevant flashy graphical advertising.
