Response to First Half of "Infomation and American Democracy"

Exploring the relationship between information technology and evolution of American politics in his book, Bruce Mimber identified four information revolutions in the American history that had deep impact on the characteristics of American politics (p23):

• First information revolution (1820s-1830s): creation of U.S. postal service and mass oriented newspaper industry --> first system for national-scale information flow --> rise of majoritarian politics
  
• Second information revolution (1880s-1910s): industralization --> interest-group politics
• Third information revolution (1950s-1970s): broadcasting/TV --> mass audience then fragmentation --> A centralized system of market-driven organizations along with specialized organizations
  
• Fourth information revolution (1990s-present): Internet --> post-bureaucratic political organizations

I find the author's angel new and interesting to me. He chose not to "invoke standard theories used by social scientists to explain the influence of technology on society, especially technological determinism and its theoretical opposite, social construction." I'm eager to find out how he deals with the topic and what conclusions he will draw in the second half of the book.
