Warner Bros. Pictures and Microsoft have partnered for the theatrical release of THE HOBBIT: THE DESOLATION OF SMAUG. Interactive ads ran across MSN, Xbox 360, and Windows 8, allowing fans to access information about the characters, events, and artifacts from the movie, as well as behind-the-scenes videos and desktop wallpaper. Users were able to download a free 3D blueprint to place in a 3D printer, allowing them to create a replica of the Key to Erebor. The download became available December 13, 2013, the release date of the film. http://www.ibtimes.co.uk/articles/526821/20131202/hobbit-3d-printer-key-erebor-warner-bros.htm
