IS POWER IN HOLLYWOOD DEFINED BY THE size of a portfolio and profit margins? Or is it the contribution to a company's bottom line? Or maybe it's the ability to make deals happen? Sweeney, THR's most powerful woman in entertainment for the fourth straight year, hits all the levers. Her Disney/ABC empire is larger and generates more revenue and profit than that of any other female executive. In 2013, she supervised a partnership between Marvel TV and ABC Studios to make four programs and a miniseries for Netflix; was instrumental in distribution deals with Cablevision, Cox, Charter and AT&T U-verse that will net billions; debuted live broadcast mobile app Watch ABC, which has been downloaded more than 13 million times; launched Disney Junior, a preschool cable channel, in 60 million households; and orchestrated Jimmy Kimmel's move to 11:35 p.m. "Our priority is staying close to the consumer," says Sweeney, a married mother of two grown children. "We are on their phones and their tablets. Being relevant and useful are very important to our company." Sweeney's portfolio includes the ABC network; Disney Channels Worldwide (107 channels in 166 countries reaching 431 million households); Radio Disney; ABC Family (and ABC Spark in Canada); ABC Studios; ABC's owned stations (including No. 1 WABC in New York); and the company's 50 percent equity interest in A+E Networks, 50 percent equity interest in Univision joint venture Fusion and Disney's equity interest in Hulu. With her boss, Disney CEO Robert Iger, extending his deal into 2016, speculation has swirled about Sweeney's next move. Where does she see herself in five years? "Doing what I'm doing now," she insists. "I have the best job in the world. And the good thing is, I know it." -- MARISA GUTHRIE
