Jim Thornton is the new announcer on "Wheel of Fortune." The KNX afternoon host has a long radio history in Los Angeles, even though he is still quite young. From a jock at KMGX/94.3 (KGIL's FM under Buckley) to hosting afternoons at KNX, with a lot of voiceover experience, one of the nicest guys in the business makes a BIG BIG move up. He steps into the shoes of the late Charlie O'Donnell, widely loved as another nice guy. Good lessons for the grouchy types in our business.
