The Pirate Bay (sometimes abbreviated as TPB) is an online index of digital content of entertainment media and software. Founded in 2003 by Swedish think tank Piratbyrån, The Pirate Bay allows visitors to search, download, and contribute magnet links and torrent files, which facilitate peer-to-peer, file sharing among users of the BitTorrent protocol. The Pirate Bay has sparked controversies and discussion about legal aspects of file sharing, copyright, and civil liberties and has become a platform for political initiatives against established intellectual property laws as well as a central figure in an anti-copyright movement. The website has faced several shutdowns and domain seizures, switching to a series of new web addresses to continue operating. In April 2009, the website's founders (Peter Sunde, Fredrik Neij, and Gottfrid Svartholm) were found guilty in the Pirate Bay trial in Sweden for assisting in copyright infringement and were sentenced to serve one year in prison and pay a fine. In some countries, Internet service providers (ISPs) have been ordered to block access to the website. Subsequently, proxy websites have been providing access to it. Founders Svartholm, Neij, and Sunde were all released by 2015 after serving shortened sentences. History The Pirate Bay was established in September 2003 by the Swedish anti-copyright organisation Piratbyrån (); it has been run as a separate organisation since October 2004. The Pirate Bay was first run by Gottfrid Svartholm and Fredrik Neij, who are known by their nicknames "anakata" and "TiAMO", respectively. They have both been accused of "assisting in making copyrighted content available" by the Motion Picture Association of America. On 31 May 2006, the website's servers in Stockholm were raided and taken away by Swedish police, leading to three days of downtime. The Pirate Bay claims to be a non-profit entity based in the Seychelles; however, this is disputed. The Pirate Bay has been involved in a number of lawsuits, both as plaintiff and as defendant. On 17 April 2009, Peter Sunde, Fredrik Neij, Gottfrid Svartholm, and Carl Lundström were found guilty of assistance to copyright infringement and sentenced to one year in prison and payment of a fine of 30 million Swedish kronor (approximately U$4.2 million, £2.8 million sterling, or €3.1 million), after a trial of nine days. The defendants appealed the verdict and accused the judge of giving in to political pressure. On 26 November 2010, a Swedish appeals court upheld the verdict, decreasing the
