Bill Marimow resigned last night as NPR’s v.p. of news and will become its ombudsman, reports the Washington Post. NPR staffers told the Post that Marimow and Jay Kernis, v.p. of programming and his immediate boss, had clashed about “the scope and nature of his responsibilities.” UPDATE: The New York Times has posted an expanded version of its original article. “Colleagues said that Mr. Marimow, a long-time print journalist and investigative reporter, was perceived as having failed to adapt quickly enough to radio, particularly as radio converges with the Internet,” the Times reports. “They also said that he was on the wrong side of an internal power struggle.” NPR’s Nell Boyce, blogging at Mixed Signals, writes about the decision from the inside in a long post. She says the mood at the meeting where Marimow’s resignation was announced was “solemn” and that Marimow was conspicuously absent.
