For those of you who missed it last week (like me) the BBC is repeating the documentary of Stephen Fry and the Machine That Made Us - it’s on again this Friday (25th Apr) at 9pm on BBC Two.

Stephen Fry goes in search of the story behind the first media entrepreneur Johann Gutenberg - the man who invented the printing press – to find out why he did it and how. The story combines both historical enquiry and hands on craft and technology. It is through these practical trials and tests that Stephen demonstrates the brilliance of Gutenberg’s invention and brings the man and his machine to life.

I’ve had a look around and you can catch it again on the BBC iPlayer and TV Replay on your set top box, as well as five parts on YouTube.
