Chris Cowan, a former principal of Rocket Science Laboratories and Angel City Factory, has joined BermanBraun as head of unscripted television. He also will oversee all video development and production in the company’s digital unit, including the building of an in-house video studio to supply BermanBraun’s three You Tube channels and websites. This is a new position. Cowan also is taking over responsibilities previously held by Jared Heinke, who was recently promoted to co-run digital division with Paco Vinoly. “Chris is one of the best storytellers and producers we have ever worked with,” said Gail Berman and Lloyd Braun, who have known Cowan for a while. Cowan’s reality series credits include Temptation Island, Joe Millionaire, My Big Fat Obnoxious Fiance and Mobbed.
