Communication Power

This book of around 500 pages is the most important work written by Castells since his influential trilogy The Information Age. Based on many years of research and writing, the book gives a comprehensive account of how the global media industries have been transformed by the revolution in communication technologies. It presents an original theory of power in the information age, emphasizing the importance of what Castells calls ‘mass self-communication’. This theory is developed in relation to a wide range of case studies, from the internet-based political campaign of Obama to the global environmental movement to prevent climate change.
