Das Internet ist derzeit voll damit und falls ihr euch auch fragt um was es dabei geht – hier folgt eine kleine Erklärung:

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