Twitter's exclusive relationship with one of its biggest stars ends tonight.
Along with the premiere goes the special relationship the comedian developed with his more than 1.8 million Twitter followers.
Shortly after being kicked to the curb by the peacock -- albeit with a gigantic check -- O'Brien resurfaced with Twitter as his new channel.
Under his buyout agreement with NBC, the former "Simpsons" writer was not allowed to appear on television until now. Avoiding any lawsuits, O'Brien took to the new age airwaves provided by the San Francisco-based Twitter. He turned his tweets into a national tour that sold out multiple nights in the Bay Area.
But with the rigors of daily late night television back on his shoulders, O'Brien has already alluded that Twitter was just a blip on his journey back to the 11 o'clock hour.
"Tomorrow, I’ll be back where I truly belong - indoors, under artificial light," he tweeted. A day later he wrote "I feel like I have something to do tonight that I keep forgetting."
Though some may argue his pale skin never looked better hidden behind the cozy confines of a thumbnail image on a computer screen.
