Reuters writes: " A U.S. judge's order to Google Inc to turn over YouTube user data to Viacom Inc sparked an outcry on Thursday from privacy advocates in the midst of a legal showdown over video piracy.
Viacom, owner of movie studio Paramount and MTV Networks, requested the information as part of its $1 billion copyright infringement lawsuit against the popular online video service and its deep-pocketed parent, Google.
Judge Louis Stanton of the U.S. District Court for the Southern District of New York ordered Google on Tuesday to turn over as evidence a database with usernames of YouTube viewers, what videos they watched when, and users' computer addresses."
