File-Sharing Doesn't Hurt Box Office Revenue

How many studies like this do we need before the industry gets it? Pirates weren't going to pay for your product in the first place, so you can't count it as "lost" revenue. New research by economist Koleman Strumpf shows that there is no significant effect of movie piracy on box office revenues. This conclusion is based on data from 150 blockbuster movies that were released over a period of six years, using the popular Hollywood exchange as an indication for the revenue impact.
