Yesterday’s announcement that The Washington Post would be sold to Amazon CEO Jeff Bezos shocked the newspaper industry. The deal is the latest in a series of consolidations, driven by a migration to online sources. Print newspaper advertising revenues have fallen 55 percent in the past five years. At The Post, revenues had fallen for seven straight years. Four days ago, The New York Times Company sold The Boston Globe for $70 million, having paid more than $1 billion for it in the early 1990s. The Post sale ends four generations of ownership by the Graham family. Diane and her guests discuss the sale of The Washington Post and the future of print journalism.
