Megyn Kelly, who arrived at Fox News 12 years ago as a television news neophyte but rose to become one of its two biggest stars, has decided to leave the network to take on a broad new role at NBC News for an undisclosed amount, people briefed on the negotiations said on Tuesday.The NBC News chairman, Andrew Lack, wooed Ms. Kelly away from Fox News by offering her a triple role in which she will host her own daytime news and discussion program, anchor an in-depth Sunday night news show and take regular part in the network s special political programming and other big-event coverage.The move will herald a seismic shift in the cable news landscape, where Ms. Kelly had become the second-most watched host   after Bill O Reilly of Fox News   and often helped define the national political debate, especially over the last year as Donald J. Trump regularly attacked her, at times in viciously personal terms.Fox News s parent company, 21st Century Fox, which is controlled by the family of Rupert Murdoch, had offered Ms. Kelly more than $20 million a year to stay after her current contract expires this year. Rival networks seeking to hire Ms. Kelly away, including NBC News, had made it clear that they could not match that money from Fox, the cable news leader for the last 15 years running.Ms. Kelly s contract is not officially up until the summer, and it was unclear whether Fox News would refuse to release her from any contractual commitments that might delay her start at a rival.The Sunday night program, which is yet to be named, would provide Ms. Kelly with a continued hand in hard news. And she would be in the mix on NBC News during major political coverage.For entire story: NYT s
