Ummm... Everyone predicted this and she trashed the company in her book and straight out said she was not likely to stay there.
She is definitely worth whatever NBC is paying her. She is one of the hottest things in news since 24/7 news started.
NBC looks to have signed a strong deal with her too offering her a daytime spot, the usual spot reporting for events and a Sunday special slot for in depth coverage to do real news. She is carving her out legacy.
What is interesting is that NBC could not match the price of Fox so she is taking a paycut. My guess is she have creative control however for her own program and maybe the daytime show.
