Does Google Need An Ethics Policy Like The New York Times
Google is really a publisher. It publishes its search results. It adds paid advertisements and the more you pay the more visible your Adwords will be. It is trying to maintain that the non-Adwords content is commercial free. However it realizes that big advertisers may well spend money to get higher in the organic results ( the publication side of the business). It needs to be visible in trying to preserve the integrity of that noncommercial content.
