This book is an impressive survey of our collective and cumulative understanding of the evolution of digital communication systems and the Internet. Whilst the information societies of the twenty-first century will develop ever more sophisticated technologies, the Internet is now a familiar and pervasive part of the world in which we live, work, and communicate. As such it is important to take stock of some fundamental questions - whether, for example, it contributes to progress, social cohesion, democracy, and growth - and at the same time to review the rich and varied theories and perspectives developed by thinkers in a range of disciplines over the last fifty years or more.

In this remarkably comprehensive but concise and useful book, Robin Mansell summarizes key debates, and reviews the contributions of major thinkers in communication systems, economics, politics, sociology, psychology, and systems theory - from Norbert Wiener to Brian Arthur and Manuel Castells, and from Gregory Bateson to William Davidow and Sherry Turkle. This is an interdisciplinary and critical analysis of the way we experience the Internet in front of the screen, and of the developments behind the screen, all of which have implications for privacy ,security, intellectual property rights, and the overall governance of the Internet.

The author presents fairly the ideas of the celebrants and the sceptics, and reminds us of the continuing need for careful, critical, and informed analysis of the paradoxes and challenges of the Internet, offering her own views on how we might move to greater empowerment, and suggesting policy measures and governance approaches that go beyond those commonly debated.

This concise book will be essential reading for anyone who wants to understand the challenges the Internet presents in the twenty-first century, and the debates and research that can inform that understanding.
