The United States of America is a polarized country marked by toxic partisan politics. The state of American politics comes from somewhere. And it might have been otherwise. It has been shaped by powerful interests, technologies, and contingent forces. One of those – one of the most important – is cable television.  A new book traces the history of cable television and the changing political and cultural landscape in the United States. In the background of the book looms an absolute bruiser of a question: Did cable television break America?On this episode of Open to Debate, David Moscrop talks with Kathryn Cramer Brownell, an assistant professor of history in the College of Liberal Arts at Purdue University and the author of  24/7 Politics: Cable Television and the Fragmenting of America from Watergate to Fox News.
