Why Keith Olbermann Is Out At MSNBC$1:
It appears that the end of the Olbermann era at MSNBC was not “ordered” by Comcast, nor was it a move to tone down the network’s politics. Instead, sources inside the network say it came down to the more mundane world of office politics–Olbermann was a difficult employee, who clashed with bosses, colleagues and underlings alike, and with the Comcast-related departure of Jeff Zucker, and the rise of Maddow and O’Donnell, the landscape shifted, making an Olbermann exit suddenly seem well-timed.
In short, he may have had the ratings but he was high maintenance. A lot of people are saying it's house cleaning before comcast next week but I think it really was a HR issue. KO was an ass to management and this was their sendoff to him.
