The new math from the perspective of advertisers is explained pretty well in "The Ulitmate Guide to Google Adwords" by Perry Marshall and Brian Todd. I'm a little more than halfway through (although we haven't done any advertising in a couple years) and it's a very interesting and well written book. The bottom line focus is the bottom line, how advertisers can get more bang for their buck, which unfortunately, means publishers will get less bang for their content. Maybe advertisers are just getting educated about how to use Adwords, or outsourcing campaign management to companies that are saving them money.
