"This means that roughly 100,000 Americans have downloaded a copy online through BitTorrent. Now, IF all these people bought a movie ticket instead then box office revenue would be just 0.5% higher."

Even though I agree with most points in this article, the 0.5% is a bit off. When a "pirate" (yarghh) decides to download a movie, they usually end up watching it with friends and/or family - not just by themselves..

Still, if you really care about a movie, you would watch it in a cinema instead of watching a bad "CAM" version.
