Reuters: Activist investor Starboard Value has disclosed a 4.5 percent stake in Media General and urged the regional TV broadcaster to sell itself to Nexstar Broadcasting and scrap its plan to buy Meredith. Starboard also said it was prepared to nominate an alternative slate of directors to Media General’s board. The hedge fund succeeded last year in replacing all 12 directors at Darden Restaurants, the owner of the Olive Garden chain.
