According to a study by the University of Minnesota, piracy in the form of BitTorrent does NOT hurt the box office here in the US.  However, the same cannot be said for overseas releases; partially because of the dates and cycles in which they are released.

So, with all of the SOPA and PIPA bills floating around, for there to be no significant drop in revenue for U.S. box offices destroys the MPAA argument.  On the other hand, releases abroad saw a decline of 7% in revenue due to piracy because titles were not available as fast.

Bottom line:  The industry is all about money; it seems that they will do whatever it takes to rake in as much money as possible.  However, with so many wealthy “big-wigs” in Hollywood is destroying the internet really worth it?
