MSNBC has officially blessed the Reverend Al with his own show. Sharpton, who's been filling in on the network's 6 PM hour for the past two months, will now host his own show, called 'PoliticsNation.'

Sharpton began filling in for Cenk Uygur in early July while he was out on vacation, and put up solid ratings in his stead. Shortly after Uygur returned, he and the network had a very public falling out in which Uygur alleged he was pressured to "tone it down."

"I've known Rev. Sharpton for over a decade and have tremendous respect for him. He has always been one of our most thoughtful and entertaining guests," said MSNBC President Phil Griffin in a statement. "I'm thrilled that he's now reached a point in his career where he's able to devote himself to hosting a nightly show. 'PoliticsNation' is going to be an incredibly strong kick-off to our evening schedule."

CNN has canceled Eliot Spitzer's nightly news show 'In the Arena,' a move that the network announced today in conjunction with additional re-shuffling of their nightly lineup. Spitzer, the former New York governor who resigned in disgrace after being caught in a prostitution scandal, used the show as a vehicle for a mainstream comeback, but it never took hold with viewers and consistently struggled for ratings. CNN had tried to re-tool the program, originally launched as 'Parker Spitzer' in the summer of 2010, but the numbers never picked up, and the network decided to cut their losses and move on.

Spitzer reflected on his brief run at CNN in a statement: "We engaged serious people in conversations about national and global issues in a way that was informative and challenging. I believe that we provided diverse and valuable perspectives during the show's tenure."

The accompanying moves will shift 'Anderson Cooper 360' into Spitzer's 8PM slot. 'AC360' will also replay again at 10PM, its current time. 'The Situation Room With Wolf Blitzer,' which had previously aired from 5-7PM, will move to 4-6, with 'John King USA' moving to 6, followed by Erin Burnett's as-yet-unnamed new show at 7PM. 'Piers Morgan Tonight' will remain in the 9PM slot.
