老Redstone做上市公司董事长做到92岁也够恋权的。。。$哥伦比亚广播公司(CBS)$ $维亚康姆(VIA)$ 
Redstone was formerly the executive chairman of both CBS and Viacom. In February 2016, at the age of 92, a week after a court-ordered examination by a geriatric psychiatrist, Redstone resigned both chairmanships, replaced by Leslie Moonves at CBS and Philippe Dauman at Viacom. Redstone then became chairman emeritus.
