Today, it is taken for granted that many shop assistants are women, but 150 years ago, being served by a shopgirl was a strange new phenomenon, and the story of how an army of women swept on to shop floors is a fascinating one. Dr. Pamela Cox presents this three-part series following the journey of the shopgirl from an almost invisible figure in stark Victorian stores, to being the beating heart of modern shops. With retail the biggest private sector employer in the UK today, this series charts how shopgirls have been central to Britain's retail revolution and at the cutting edge of social change.
