Just finished this one. Definitely a joy, and just full of info relevant to the Net Neutrality fight. Starting with Bell and his telephone, Wu traces the history of the inventors and the moguls who created our current information/communications systems. The history, and machinations of Bell/ATT are especially well documented, if not also maddening.
