NBC/Universal confirmed the news in a statement Friday night.
"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."
Olbermann made the announcement in his typical deadpan style, evoking scenes from the film "Network" and thanking viewers for keeping him on the air for six years.
