Wikipedia founder Jimmy Wales explains 24-hour shutdown
The English version of Wikipedia will go offline for 24 hours on Wednesday, in protest at proposed anti-piracy laws in the US.
The encyclopedia's founder, Jimmy Wales, is opposing the "Stop Online Piracy Act" that is being debated in Congress.
He told Radio 5 live's Tony Livesey the anti-piracy law would be a form of censorship.
