Four Decades of Evolution in NYC

As New Yorkers prepare to elect a new mayor for the first time in 8 years, a new book provides a deep dive into how the city evolved under four previous administrations -- Koch, Dinkins, Giuliani and Bloomberg. It’s called New York, New York, New York: Four Decades of Success, Excess and Transformation. Author Thomas Dyja says over the last few decades, three different New York Cities have emerged. He joins us on this week's Cityscape to talk about these different versions of New York and more.
