Transcript -- The Internet at 40

2009 is the 40th anniversary of the first computer network - the precursor of the internet -  and the 20th anniversary of the brilliant idea that led to the creation of the world wide web. What exactly is the internet, and how does it differ from the world wide web? Who were its pioneers, and what technological surprises has it sprung?  This album opens with a specially recorded interview with John Naughton, Professor of the Public Understanding of Technology at The Open University and author of 'A brief history of the future - the origins of the internet'. He explores some of the key moments in the short but spectacular history of an extraordinary phenomenon, the people who made them happen, and some of the problems that have emerged. The album also features archive interviews with Tim Berners-Lee, Vint Cerf, Donald Davies and other pioneers of the internet age, recorded in the late 1990s. The album is completed by a newly recorded interview with Rodney Harrison, lecturer in Heritage Studies at The Open University, in which he talks about his research into Second Life: Cyber-Archaeologies, Heritage and Virtual Communities. The interviews are presented by radio journalist Penny Boreham.
