Reuters: Google has asked a federal judge to require three major movie studios to comply with subpoenas it believes may help show they conspired with Mississippi Attorney General Jim Hood as he investigated the Internet search company. Google said Viacom, Twenty-First Century Fox and Comcast’s NBCUniversal “have produced nothing” in response to the March 12 subpoenas, and cannot claim the requested material is irrelevant or privileged. Google sued Hood, a longtime critic, last Dec. 19 to block his probe of whether it should be held civilly or criminally responsible for encouraging sales of objectionable materials.
