This is not the first time the movie business has been threatened by technology. “In the 1950s, as today, theaters were under siege, their audience being lured away by a dazzling new technology. Today’s competition comes from the Internet, computer games and home entertainment centers. Then the enemy was television. “How do you compete with free?” theater owners moaned, the same mantra we’ve heard from record executives complaining about unauthorized file sharing. My response has always been the same: You’ve got to embrace the future.”
