Also has sold shares steadily to fund efforts to deliver socially conscious messages and solve world problems. Valuation of Pivot TV cable network rose, but Participant Media film studio stake held steady.

THE BUZZ: Triumphant year as socially conscious film company Participant struck Oscar gold with best picture win for “Spotlight.” Put up $200 million from Participant to launch film, television, and digital content creation company Amblin Partners with Spielberg; company will be housed at Universal Studios. Hired new chief executive for Participant, former Universal honcho David Linde. Participant continuing with socially conscious films: next up, “Deepwater Horizon,” about the disastrous 2010 BP undersea oil spill in the Gulf of Mexico, set for release this fall. Pivot, cable network targeting millennials launched three years ago now available to 51 million cable households; network has searched for strategic partner. His socially conscious hedge fund Capricorn Investment Group joined with Vision Ridge and Grantham Foundation for Protection of the Environment to form $430 million Sustainable Asset Fund, one of largest environmental-focused funds ever.
