A new study says that most movie pirating is done by movie industry insiders. “Seventy-seven percent of films uploaded during this period were apparently created during production or distribution. Some simply appeared online before their cinema release – meaning they must have been leaked. Others were posted after their cinema release but displayed text indicating they were made from a pre-release review DVD. Some even showed evidence that they had yet to be edited, for example, they might contain a stray microphone at the top of the frame.”
