Viacom Chief Executive Philippe Dauman resigned late last week, bringing to a close the struggle he's waged with Shari Redstone over the past several years for control of the company, according to The L.A. Times. The conflict centered largely around questions of founder Sumner Redstone's succession plans, his mental competence and the possibility of undue influence on the part of his daughter, Shari. A settlement agreement approved Thursday evening will end ongoing cases in Massachusetts and Delaware (assuming it's approved by the court). Dauman will be replaced by Thomas Dooley, a long-time Viacom employee.
