Since 1995, 65 commercial video games based on the Lego construction system have been released, with two further titles announced. After the second game, Lego Island, developed and published by Mindscape, the Lego Group opened publishing division Lego Media to further release Lego-themed games based on their production line. After becoming Lego Software in 2001, and Lego Interactive in 2002, the publishing division closed its doors. Former Lego Interactive staff founded company Giant Interactive Entertainment to further carry on the license for Lego-themed video games, and publish from that point on. After a two-year partnership with THQ and two games released, Giant Interactive Entertainment was purchased and merged with Traveller's Tales during the development phase of Lego Star Wars: The Video Game. With the merger, head company TT Games was founded, Traveller's Tales became the development division, and Giant Interactive became TT Games Publishing, the publishing division. TT Games Publishing has since licensed several properties for use in their video games, including Star Wars, Batman and Rock Band, among others. In 2007, TT Games acquired developer Embryonic Studios, for it to become TT Fusion. TT Games and its subsidiaries were acquired by Warner Bros. Interactive Entertainment on November 8, 2007, who, from that point on, became the Lego video games' publisher and licensor.
