THR's Women in Entertainment 2011: Power 100

Berwick added two new titles to her portfolio this year: president of Style Media and U.S. citizen. "At the start of the year, every employee does company and personal goals to achieve by the end of the year, and becoming a citizen was mine," explains U.K. native Berwick, who resides in Manhattan with her husband and 8-year-old son. "I became an American citizen by October."

Bravo is on pace to have its best year to date (the network launched 30 returning and original shows in 2011, including offshoots of juggernaut franchises Top Chef and The Real Housewives) as the No. 12 ranked network in adults 18-49, but Berwick recalls a time just a few years back when the cable network barely broke the top 20. "We've climbed up the ranks and done it all on the strength of our original programming," she says.

The network has increased its 2011 original programming roster by 20 percent with such shows as Most Eligible Dallas and Million Dollar Decorators and plans to add another 20 percent in 2012. With Bravo now in somewhat of a well-run cruise control, Berwick can turn some of her focus to her new role at the Style network. "We have a well-oiled machine at Bravo, and I think we can translate some of that to Style," says Berwick, who plans to use the Bravo business model during the Style network rebrand. "It's on an upward trajectory. We're already the fastest growing network for women this year."

Berwick says she hasn't figured out a way to add more hours to the day but manages to incorporate some mommy time into her work: "My son occasionally sees cuts before they're edited for language," she admits. "He likes to tell me when I need to put a 'beep' in.
