Stephen Fry examines the story behind the first media entrepreneur, printing press inventor Johann Gutenberg, to find out why he did it and how, a story which involves both historical enquiry and hands-on craft and technology. Fry travels across Europe to find out how Gutenberg kept his development work secret, about the role of avaricious investors and unscrupulous competitors and why Gutenberg's approach started a cultural revolution. He then sets about building a copy of Gutenberg's press.
