Google Inc. (NASDAQ:GOOG) has settled with the U.S. Justice Department for $500 million to avoid prosecution on charges that they knowingly accepted millions of dollars in illegal ads from online Canadian pharmacies. Google said that they banned the advertising of prescription drugs by Canadian pharmacies in the U.S. “some time ago,” but “it’s obvious with hindsight that we shouldn’t have allowed these ads on Google in the first place,” said the company.
