An anonymous reader writes "For years, the reaction of the big entertainment companies to digital disruption has been to try and restrict and control, a wrong-headed approach that was bound to backfire. But the entertainment companies were never known for being forward thinking whether it was radio in the 20s or cassette tapes in the 70s or VCRs in the 80s or Napster in the 90s. The reaction was the always the same. Take a defensive position and try to battle the disruptive force. And it never worked. And DRM was perhaps the worst reaction of all, place restrictions on your content that punish the very people who were willing to pay for it, while others were free to use it without restriction. It was an approach that never made much sense, and it's good to know that mounting evidence proves that's the case."
