If you are running Google AdSense in  all its flavors (for content, for search, for feeds) since ages ago, have you ever wondered how much money Google is earning from it?  It took Google this long to divulge this information so might as well create some noise about it, right? In the spirit of greater transparency with AdSense publishers, Google reports that  for AdSense for Content, it gets 32% which covers for Google's costs for its continued investment in AdSense.
