Maybe, just maybe the idea of adding Keith Olbermann to the NFL on NBC roster is paying off for his MSNBC show. Countdown was the number one show in all of cable news Friday night, in the 25-54 demo (live+ same day DVR). Olbermann’s Friday night win comes after his Thursday night appearance during halftime of the Saints-Colts game. An estimated 16.5 million viewers (18-49) watched the game.

>More: an NBC insider adds the big story here is that this is the first time Olbermann has beaten O’Reilly, not a substitute host, in the key demo. The insider adds, “KO has been trending in that direction for weeks.”
