Sherry Lansing, a powerful studio boss who led the career path for female Hollywood executives, will leave her post as chairwoman of Viacom Inc.'s Paramount Pictures at the end of next year when her contract expires.
Her announcement Tuesday comes on the heels of several management shake-ups at Viacom, including the departure of Jonathan Dolgen, who had shared power with Lansing at Paramount and left shortly after Tom Freston and Les Moonves were made co-presidents of Viacom in June.
It also comes after several years of lackluster performance at Paramount and pledges by Freston and Viacom chairman Sumner Redstone to revitalize the ailing studio. Lansing, 60, said she will remain with Paramount until her contract expires. She is a former actress and model who held the top film jobs at three studios during her career.
