A statement from NBC Universal revealed the move late Friday.
"MSNBC and Keith Olbermann have ended their contract," it read. "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 ended his show Friday night announcing his departure in typical deadpan style, evoking scenes from the film "Network" and thanking viewers for keeping him on the air for eight years.
"In the mundane world of television goodbyes, reality is laughably uncooperative," Olbermann said before launching into a story about his exit from ESPN 13 years ago.Olbermann was suspended for 2days last November (2010) after NBC found out that he donated to three Democrats seeking federal office. One of them was U.S. Rep. Gabrielle Giffords. The said donations violated an NBC policy that requires employees of the news organization to obtain permission ahead of any political donations or activities that could be deemed as a conflict of interest.
"As God as my witness, in the commercial break just before the emotional moment, the producer got into my earpiece and he said, 'um, can you cut it down to 15 seconds so we get in this tennis result from Stuttgart,'" he said, half-smiling, pausing for composure.
"So I'm grateful I have a little more time to sign off here. Regardless, this is the last edition of Countdown."
