MSNBC extends Olbermann’s contract.

“Keith Olbermann will continue to be a thorn in Bill O’Reilly’s side for at least four more years,” MSNBC reports. Olbermann has agreed to a “second term” with NBC News that “will take him into 2011.” Besides hosting “Countdown,” Olbermann will now “contribute occasional essays to ‘NBC Nightly News’ and there will be two prime-time ‘Countdown’ specials a year on NBC.”
