Today executive producer Jeff Zucker will take over as president of NBC's entertainment division in January, replacing the embattled Garth Ancier. Zucker who has been with NBC for 14 years in different capacities has served as Today's top dog since 1994, during which time the show has enjoyed record ratings and generated huge profits for the network. "This next step I am taking may well prove to be my greatest challenge yet at NBC," Zucker says. "I am tremendously proud of all that I have accomplished with the staff at Today, but I feel like the time is right for this next chapter of my career." NBC West Coast President Scott Sassa says that he hopes Ancier will stick around in a "significant capacity," but he did not elaborate on what that meant.
