CEOs, Comcast (Roberts) and NBCUniversal (Burke)
Comcast's ownership of NBCUniversal may have been endlessly parodied on the TV show 30 Rock, but CEO Brian Roberts' $13.8 billion gamble on the television network is finally paying off, thanks to a resurgent entertainment division at NBC. Steve Burke presided over a stellar year for the network, boosted by its high ratings and ad revenue during the Olympics, as well as successful television shows like The Voice and Revolution. NBC's movie studio division also produced hits like Ted, The Lorax and The Bourne Legacy. Those wins, coupled with strong performance by its core cable business pushed Comcast's shares up by more than 58% this year. --Omar Akhtar
