At a Nov. 30 event at Columbia University, “Big Media: Pro and Con,” Journalism School Dean Nicholas Lemann analogized media policy to a football field: Just as the size and shape of the field dictates the way the game is played, so too does media policy dictate the development of American telecommunications. And on the heels of FCC Chairman Julius Genachowski’s announcement last week of a new net neutrality proposal, we see more clearly than ever that government legislation and regulation are crucial to this field. In that vein, Columbia Journalism School Prof. Richard R. John’s book Network Nation: Inventing American Telecommunications, published in May, makes the case that policy intervention has been commonplace throughout American history with a sweeping survey of the history of electrical communications from the early Republic to the modern day.
