Do the news media have any role in the transformation of war and warfare? A constellation of labels by academics and practitioners have been coined in the last twenty years to describe the new forms of a phenomenon as old as the human race. However, this book claims that it remains to be fully understood what the specific role of the news media is in this process. It argues that the news media, old and new alike, alter the cognitive and strategic environment of the actors of war and politics and change the way these interact with one another. Building on a four-dimensional definition of power and focusing on the role of television, this book recognises the importance of interactions upon the understanding of any social phenomenon. It suggests that the nature of war is changing partly because it is no longer just a matter of linear strategic interactions but also, and mainly, of 'mediated' ones.
