An 11-part television history of Britain at work in the 20th century. 10: The Shock Wave
No other industrial revolution has been as rapid or as far-reaching as that of electronics. And it was in Britain that it all began. From the early days of valve and radio manufacture, Britain's new industry set the pace.
Television had just begun when the Second World War brought radar, and an unprecedented research effort. The industry has continued to grow and, today, affects all our lives. Yet, despite world-beating inventions and a skilled workforce, Britain has not taken a leading role in the mass production of electronics.
Assembly workers and engineers describe the excitement and risks of rapid change, on the frontiers of science.
