In a new venture for BBC Worldwide, the BBC’s commercial arm will tomorrow offer a series of digitally remastered Doctor Who stories to rent via Facebook. By using Facebook credits, users visiting the official Doctor Who page will be able to stream a selection of nine stories (each containing several episodes) from the history of the Time Lord, including digitally remastered classics such as 'Tomb of the Cybermen' as well as modern day favourites 'Silence in the Library' and 'End of the World'. 'The Greatest Show in the Galaxy' will be a Facebook exclusive, having never been released on DVD.
