Last night, Keith Olbermann reincarnated Countdown on Current TV and it was pretty much the same exact show he had on MSNBC before the network gave him the boot. To call it "new" is a bit of a stretch, but Olbermann stopped by tonight's Late Show with David Letterman to promote the program and read off tonight's Top 10 list, "Reasons to Watch the New Countdown with Keith Olbermann." Video of the segment is above.

Five months after MSNBC canned him, Keith Olbermann returned to television tonight as Countdown made its debut on Current TV. It's pretty much the same exact show: The new network is basically the only difference between this incarnation of Countdown and the last one. But just in case you have any doubts, Olbermann's typically over-the-top "special comment" this evening—in which he claims that he's the "last line of defense" when it comes to protecting America's independence from being taken away by evil corporations—is above.

Keith Olbermann's career at MSNBC is over. The network announced this evening that it terminated its contract with Olbermann effective immediately, and the Countdown host shared the news in typically dramatic fashion on his show tonight. Olbermann's final words below.

At the end of tonight's broadcast of Countdown, MSNBC powerhouse Keith Olbermann dropped a bomb on his viewers: "This is the last edition of Countdown," said the stone-faced anchor. Olbermann was reportedly fired by MSNBC today. His final words, inside.

Tonight, our really short national nightmare ended when Keith Olbermann reclaimed the Countdown anchor chair. Olbermann wasted no time referencing his suspension when he slowly moved into the frame during a tongue-in-cheek introduction. Update: Olbermann's self-referential/gloat-heavy outro is also inside.

During tonight's Countdown, Keith Olbermann made a major announcement: effective immediately, he's suspending the show's "Worse/Worser/Worst Person in the World" segment, with an aim at eventually killing it altogether. What brought Olbermann to this decision? Jon Stewart, naturally! Watch inside.

Last night on Countdown, Keith Olbermann named Rick Sanchez the "Worser Person in the World" for the apology (non-apology?) that the former CNN buffoon issued earlier today. Inside, video of Olbermann's slam, during which he called Sanchez's remarks decidedly anti-semitic.

On tonight's Countdown, Keith Olbermann welcomed CNET's Caroline McCarthy to talk about the new Google-Verizon "deal with the devil" that may end net neutrality as we know it. As you might have guessed, Keith isn't a fan of the possibility.

Since Tuesday, the world has stood dumb-struck at the victory of Alvin Greene in the SC Democratic Primary. He's unemployed, looking at a felony charge for showing a college coed a porn image and giving interviews. Inside, the best ones.

Angry Keith Olbermann clearly burns with the desire to say swears on TV. What else can explain his barely-contained glee at playing a clip of Carl Levin saying the word "Shitty" a bunch of times at today's Goldman Sachs hearing?
