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, and often spoofed, British institution. The Open University (or OU) is now 40 years old, and Lenny Henry tells its story and reveals how the OU changed his own life. Featuring contributions from Sir David Attenborough, Myleene Klass and Anna Ford.
