Overview: The Changing Face of Britain. Episode 3. Last in the documentary series about Coronation Street's rich history. Over the past 50 years, the soap has moved with the times and held up a mirror to an ever-changing world. This episode examines how real life and life on the Street have often gone hand-in-hand - from the strikes which closed Mike Baldwin's factory and forced Corrie off the air in the late Seventies to the eco-warriors who inspired a tree-top protest by Emily Bishop.
