"MSNBC and Keith Olbermann have ended their contract," said a statement issued to The Hollywood Reporter Friday. "The last broadcast of 'Countdown with Keith Olbermann' will be this evening. MSNBC thanks Keith for his integral role in MSNBC's success and we wish him well in his future endeavors."
Olbermann had been the host of "Countdown" since 2003.
