Tellem made her bones as president of CBS Television Studios, but it's the work she's doing with Microsoft that's really innovative. Lured to Redmond, Wash., to launch an Xbox Studio, she and her team are creating programs that will be available exclusively through the Xbox platform. (The programming will reportedly be a mix of short- and long-form, with many shows having an interactive layer built on them.) That's bound to put additional pressure on her former employer and other networks.
"We now have a tremendous opportunity to transform [the Xbox] into the center of all things entertainment—from games, music and fitness to news, sports, live events, television series and movies—so consumers have one destination for all their entertainment needs," she said.
