Amazon is not involved in the purchase; Bezos is buying the Post from the Graham family--which has owned it for four generations--entirely on his own, out of pocket. $250 million, it should be said, is less than one percent of Bezos's net worth, which is estimated by Bloomberg to be about $27.9 billion. (It's also the quarter the price of Instagram, which sold to Facebook last year for a cool billion dollars.) In another post, published on the Post, which he now owns, Bezos assured the employees of the Post that "The values of The Post do not need changing. The paper's duty will remain to its readers and not to the private interests of its owners." He also said that he would delegate day-to-day management of the newspaper to existing management.
