Sometime in 2000, Sony patented a process that would 'verify a disc as legitimate, register the disc to that particular game console, then wipe out verification data so the disc would be rendered unreadable in other PlayStations'. Despite unrest in the gaming community over this technology, the company has repeatedly stated they have no plans to use it in the PS3. The LA Times explores this persistent debate, examining why Sony developed the tech and why gamers are nervous. From the article:
"Whatever Sony's plans, the tempest [over the patent] illustrates the changing nature of ownership as millions of people accumulate vast collections of digital entertainment. Few people realize that when they buy software or music or movies, they are actually buying a license to use, watch or listen. That's why it violates copyright laws for people to sell copies of their music collection."
