Popular opinion suggests that information has become a distinguishing feature of the modern world. Where once economies were built on industry and conquest, we are now instead said to be part of a global information economy. In this new and thoroughly revised edition of his popular book, author Webster brings his work up-to-date both with new theoretical work and with social and technological changes - such as the rapid growth of the internet and accelerated globalization - and reassesses the work of key theorists in light of these changes. This book is essential reading for students of contemporary social theory and anybody interested in social and technological change in the post-war era.
