"To promote prosperity, creativity, entrepreneurship, and innovation by combating the theft of U.S. property, and for other purposes." —H.R. 3261

The Stop Online Piracy Act (SOPA), also known as H.R. 3261, is a bill that was introduced in the United States House of Representatives on October 26, 2011, by Representative Lamar Smith (R-TX) and a bipartisan group of 12 initial co-sponsors. The bill expands the ability of U.S. law enforcement and copyright holders to fight online trafficking in copyrighted intellectual property and counterfeit goods.[2] Now before the House Judiciary Committee, it builds on the similar PRO-IP Act of 2008 and the corresponding Senate bill, the PROTECT IP Act.[3]

The PROTECT IP Act (Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act of 2011; United States Senate Bill S.968) is a proposed law with the stated goal of giving the US government and copyright holders additional tools to curb access to "rogue websites dedicated to infringing or counterfeit goods", especially those registered outside the U.S.

Stop SOPA has been all over the net, if you haven't come across it yet. Reddit seems to be at the forefront of addressing the concerns the bill raises, with threatening a blackout pretty soon. Facebook and Google are being urged to take a stand as well. I laugh.
Censoring the internet is, well, impossible. Until something like this is pushed through, that is. I wonder what will happen?
