epa03064979 (FILE) A file photo dated 05 August 2005 showing logos of the internet cyclopaedia 'Wikipedia' in several languages at the 'First International Wikimedia Conference' in Frankfurt, Germany. Online encyclopedia Wikipedia shut down its English-language site on 18 January 2012 and Google blacked out its famous logo in a 24-hour protest at proposed anti-piracy legislation in the
United States. The unprecedented move came in reaction to two bills making their
way through the US Congress, the Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA). EPA/BORIS ROESSLER
