With Comcast's purchase of NBC, the cable giant's chief executive practically controls the future of television. Roberts built Comcast from a mere distributor of content to one of the most powerful content providers in the world. The merger is the first time a cable company has taken control of a broadcast network, and Roberts is being tasked to guide Comcast as a growing number of viewers turn to online streaming video to get their programming.
