MSNBC host Keith Olbermann announced Friday night that it would be his last "Countdown" show on the network.

The cable news channel released a statement saying, "MSNBC and Keith Olbermann have ended their contract. 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."

A spokesman told the Associated Press that the decision had nothing to do with the acquisition of NBC Universal by Comcast.

Olbermann, who ended his show with a poem, did not elaborate to his audience why he was leaving. He was suspended without pay for two days in November by MSNBC for making political donations to three Democrats.

Conservative commentator and webmaster Andrew Breitbart sent out a tweet shortly after the announcement offering Olbermann a new gig:

I supported @ last time @ canned him & now Im offering him my Big Fantasy Sports editorial slot!
