The Protect IP Act, better known as PIPA, refers to an U.S. anti-piracy bill designed to block and even remove websites dedicated to infringing activities, and especially to shut down overseas pirate sites. Introduced in 2011 by US Senator Patrick Leahy, and highly supported within the US Senate, the PIPA is strongly criticized by many websites including Wikipedia, Facebook, Reddit, Google, which have protested by blacking out their homepages. Moreover, the PIPA is defined by the online community worldwide as a threat to both the Internet security and virtual democracy. Learn more about PIPA and its text content in this book.
