Last Friday, Conan O'Brien bid The Tonight Show adieu. Jay Leno will reclaim the "King of Late Night" title in March. But to understand the present, one must know the past: here's how we got to where we are now.

Conan O'Brien just closed out his final episode as host of The Tonight Show, and what a show it was: hilarious shenanigans, Steve Carell, Tom Hanks, Neil Young, a tearful statement of gratitude, and Will Ferrell with a mothereffing cowbell.

If this season of Jersey Shore proved nothing else, it's that the native "guidos and guidettes" enjoy their violence: brawls, fights, and epic punches to the face. Here, you can enjoy every single fight in rapid succession.

Moments ago, Conan O'Brien confirmed that tomorrow is his last day as host of The Tonight Show, but promised to go out with an NBC-bashing bang. Meanwhile, Jay Leno announced his return to 11:35 as David Letterman continued eviscerating him.

Tonight, while David Letterman and Jay Leno were busy insulting each other, Conan O'Brien did everything he could to piss off NBC: the return of the Masturbating Bear, a $1.5 million prop and a bombshell dropped by guest Adam Sandler.

Artie Lange visited Late Night in November 2008, as Conan O'Brien prepared his move to Los Angeles to take over The Tonight Show. Lange did not want O'Brien to leave, and his words about it then ring eerily true today.

If it wasn't clear before, it is now: David Letterman hates Jay Leno. Letterman repeatedly destroyed Leno on his show tonight, implying he's a thief and all-around bad guy. And while O'Brien made fun of NBC, Leno took personal digs.

Tonight, Jay Leno spoke seriously on the NBC late night controversy for the first time, skirting blame and saying, "Conan's show... was not doing well." Later, David Letterman continued his Leno-bashing, while O'Brien further took NBC to task. Videos inside.

Jay Leno has become the most hated comedian in America. But he's not the only one! These comedians are also hated because they're unoriginal, obnoxious, and out of touch. But one theme ties them all together: they're not funny.

Five years ago, Jay Leno promised Conan O'Brien he'd step aside in 2009, vowing to hand over The Tonight Show without repeating the bitter fallout of the first late night war. This past week he broke that promise.

Following yesterday's late night melee, we wondered: after four nights of infighting, would détente emerge this evening? Nope! Conan O'Brien embarrassed NBC in the best way ever, Jay Leno personally attacked David Letterman, Jimmy Kimmel mocked everyone, and much more.

This evening's late night lineup definitely delivered the drama. For the first time, Jay Leno went after Conan O'Brien, before being DESTROYED on his own show by Jimmy Kimmel. O'Brien continued to go rogue, Letterman didn't let up, and more.

The day after Co Co said No No to moving his time slot, Gawker.TV covered all of the late night shows to make sure not a single quip or sly remark escaped our radar. And tonight, nobody held back.

Conan announced that he refuses be pushed back to the 12:05 slot, essentially ending his tenure at NBC. He cited NBC not giving his show the chance to grow. Which got us thinking, what other shows were prematurely snuffed out?

Conan O'Brien has officially gone rogue. On the heels of Friday's unusually harsh monologue, O'Brien went after the network that screwed him even harder tonight. Also: David Letterman and Craig Ferguson chimed in with some NBC/Leno digs of their own.

The Jay Leno Show opened moments ago with more statements from the host regarding its cancellation and possible move to the 11:35 PM time slot currently occupied by Conan O'Brien, including confirmation of O'Brien's displeasure with the situation.

NBC Nightly News took an uncharacteristically personal turn tonight, as anchor Brian Williams opened the broadcast with the news that Mark McGwire admitted past steroid use today in a letter to his former team. Inside, video of Williams' surprising statement.

The Simpsons just celebrated its 20th Anniversary, and names like Homer and Bart have become ingrained upon our cultural identity. However, they've invented many other names, not as immediately recognizable. Here's a massive compilation of the best and funniest.

Nicolas Cage is reportedly broke. He's also the worst actor of his generation (according to us). The Weekend Update segment on tonight's SNL made fun of the latter with a near-perfect impersonation of the movie star by Andy Samberg.

Just moments ago on The Tonight Show, Conan O'Brien addressed the reports that NBC is giving the 11:35 PM time slot back to Jay Leno for the first time since the news broke—and he didn't hold back. Video inside.
