In 1969 change was in the air. Man stepped on the moon and Britain launched a revolutionary new kind of university, one where the lectures were televised and the students could study at home. It was greeted with scepticism, both by politicians and academics, but went on to become a much loved institution. The Open University is now forty years old, and Lenny Henry tells its story and reveals how it changed his own life. With contributions from Sir David Attenborough, Myleene Klass and Anna Ford.
