Stars and programme-makers come together to look back at landmark series from BBC Two, including the long-running arts series Arena and David Attenborough's natural history masterpiece Life on Earth. The channel became home to hard-hitting and groundbreaking drama including Law & Order, Boys from the Blackstuff, Tinker, Tailor, Soldier, Spy and Empire Road, as well as classic comedies such as Fawlty Towers and Yes, Minister. In the 1980s, documentary strand 40 Minutes was launched, politicians began to be grilled on Newsnight, Janet Street-Porter's 'yoof' slot DEF II went on air and The Late Show brought late-night cultural discussion to the nation's screens.
