Change is afoot at CNBC. We hear the cable network is cutting its two-hour “Power Lunch” show in half and will devote the leftover hour to a new show, “Strategy Session,” hosted by David Faber, and an expanded version of “Fast Money Halftime Report,” from 15 minutes to 30. We also hear CNBC approached “Mad Money” host Jim Cramer about helming a second program but “he doesn’t want to work with [VP of Strategic Programming and Development] Susan Krakower,” a source tells us. We hear that Krakower, whose blow-up with former “Fast Money” host Dylan Ratigan prompted him to leave the show, isn’t confident her contract will be renewed. A CNBC rep says, “The story is 40 percent accurate. But here’s a fact: Jim and Susan are critically important contributors to CNBC’s success and will be for years to come.”
