Boston, it appears, will be the first major American city to lose its daily newspaper: The Boston Globe will shut in 60 days, The New York Times Co. announced today. The decision comes on the heels of discussions well into the night. The New York Times Co. sought $20 million in concessions from union officials but an agreement wasn’t reached by the midnight deadline. The company will file a notice today that it will shutter its plant, and that the Boston Globe, which is expected to lose $85 million this year, will publish only through a 60-day period. The decision is reversible, the Globe says, based on changing financial conditions at the newspaper. If it shutters, Boston will be left with one daily newspaper: the Boston Herald, a tabloid with 10 reporters.
