And in media news, MSNBC host Keith Olbermann has left the network after eight years. On Friday, Olbermann ended his nightly Countdown broadcast with the announcement it would be his last. Although he didn’t specify a reason, Olbermann’s departure came one day after the Justice Department gave final approval to media giant Comcast’s takeover of MSNBC’s parent company, NBC Universal. Olbermann was briefly suspended in November after it was revealed that he had donated money to three Democratic candidates in violation of MSNBC’s policy.
