Big changes at NewsHour. No, the rumors aren’t true: Jim Lehrer isn’t stepping down. Not exactly. What will happen is he’ll have a co-anchor. That spot will rotate among Gwen Ifill, Judy Woodruff and Jeffrey Brown, all currently with the show. But, e.p. Linda Winslow told The New York Times, “This is not a succession plan in disguise.” It’s part of a major overhaul of the show, including the new name PBS NewsHour, that will be unveiled at PBS Showcase tomorrow.
