Former New York Gov. Eliot Spitzer's prime-time talk show was cancelled by CNN on Wednesday, with plans to replace it with Anderson Cooper 360 effective August 8.

The nine-month-old show In The Arena hosted by Spitzer, most notable for resigning as New York governor in 2008 amidst a prostitution scandal, was cancelled in order to boost CNN's primetime audience, which has been dwindling as the news network has progressed.

I believe that we provided diverse and valuable perspectives during the show's tenure. I thoroughly enjoyed my time at CNN, Spitzer said.

Spitzer's show, airing 8 p.m. ET daily, did poorly in the ratings for CNN, having to compete against Bill O'Reilly on Fox News and Keith Olbermann on MSNBC during the same time slot. Foreshadowing its cancellation, Spitzer's cohost Kathleen Parker left back in February due to the unsatisfactory ratings and a steady decline in viewers.

CNN has been strategizing to boost its ratings during prime time, since the network is most notably known for being simply a 24 hour news network.

This switch-up is part of CNN's plan to stabilize, if not increase, its ratings. CNN has held the third place position since the fall for the 8pm primetime slot, following directly behind Fox and MSNBC.

Ken Jautz, Executive Vice President of CNN, said, The new line-up showcases anchors who are experienced reporters in covering stories that span the globe. This line-up ensures viewers access to the best of what CNN has to offer whenever they tune in at night.

The changes to CNN's primetime line will be implemented on August 8, shifting Anderson Cooper's AC360 to 8 p.m. ET with a rebroadcast at 10 p.m. ET. The unaffected Piers Morgan Tonight will remain at 9 p.m.
