Seven Ages of Britain - Age of Ambition

The 20th century saw ordinary Britons upturning ancient power structures and class hierarchies. The catalyst was the First World War, which embroiled the whole nation and called traditional values into question. The result was an ever-growing democratisation of culture, with art coming off gallery walls, becoming an instrument of self-expression at the service of the individual. David Dimbleby looks at some of the great masterworks of modern British art, but also champions lesser appreciated art forms like broadcasting and domestic design.
