Chairman, NBCUniversal Cable Entertainment Group, Comcast, 67
Even in an increasingly challenged traditional TV landscape, Hammer’s star continues to rise. In 2016 her division increased in both profit and revenue for the 13th consecutive year. Some 113.5 million weekly viewers tuned in to watch the 137 original programs available on her channels, which include Syfy and USA Network—the latter airs The Sinner, currently the No. 1 new series on cable. And Hammer’s not going anywhere: She recently renewed her contract with NBCUniversal, which will take her into her seventies.
