nk497 writes "Google has released details on the copyright takedown notices it's received over the past year, and the most requests by far have been from Microsoft. Over the past year, Google has received DMCA takedown notices for 2,544,209 URLs over Microsoft-related piracy, with NBC and the RIAA ranking second and third. Many of the reports do not come directly from companies such as Microsoft, but via firms set up only to chase copyright issues. The most popular targets appear to be file-sharing sites. 'These days it's not unusual for us to receive more than 250,000 requests each week, which is more than what copyright owners asked us to remove in all of 2009,' said Fred von Lohmann, Google senior copyright counsel, adding it takes on average 11 hours for Google to take action."
