New York Times media columnist Jim Rutenberg reports:

If true, this could be a pretty major media shakeup. Not only has Kelly been a fixture at Fox News, but she’s also been a ratings powerhouse.

More from the NYT:

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 new deal, which NBC is expected to announce imminently, brings to a close the most anticipated television news contract negotiations since Katie Couric signed with CBS News in 2006, for $15 million a year.

Stay tuned …
