Summary: Google began documenting government requests for content removal in 2009. Periodic transparency reports informed users about demands made by government agencies, breaking requests down by country and targeted service (YouTube, Google search, Blogspot, etc.)

In October 2011, the section dealing with US government agency requests included a note indicating Google had refused a questionable demand to take down a YouTube video.
