Great article from Freaknomics about the truth behind piracy numbers. The whole SOPA/PIPA debate opens up some serious thought about piracy - a concept that you can't really debate is good. However, the supporters of the bill (and, esp. the lobbyists) make the claim that $250 billion per year is being lost to piracy; Freakonomics refutes that rather deftly. Apparently it's closer to $58 billion - not a minuscule amount by any means but a far cry from the proposed loss. It's a quick read and an excellent starting point for further discussion of the issue.
