Sony, the only media conglomerate that owns a movie studio and manufactures Blu-ray players and videogame devices, announced Monday that from now on the Blu-ray version of its movies will contain a digital file that can be transferred directly from a Blu-ray player to its PlayStation Portable game system. The digital copy cannot be played on other portable devices. The new discs will debut on Nov. 10, with the release of Godzilla and The Ugly Truth. In a statement, Rich Marty, head of new business development at Sony's home entertainment unit, said that the new discs will showcase "the unique advantage that the PlayStation 3 brings to the Blu-ray consumer."
