An interviewer on the comeback trail: Larry King, who left CNN’s regular stable a little over a year ago, is getting back in the game with the help of Carlos Slim, the Mexican multi-billionaire who’s been helping the NYT stay afloat in recent years. King, 78, would be the key star at the helm of Ora.tv, Slim’s new online-only television network, which is set to launch later this year. Good idea? Bad? We’ll say this much: Piers Morgan is a pretty solid replacement for King.
