Cultural Studies signals a major academic revolution for the 21st century. But what exactly is it, and how is it applied? It is a discipline that claims not to be a discipline; it is a radical critical approach for understanding racial, national, social and gender identities. "Introducing Cultural Studies" provides an incisive tour through the minefield of this complex subject, charting its origins in Britain and its migration to the USA, Canada, France, Australia and South Asia, examining the ideas of its leading exponents and providing a flavour of its use around the world.
