Officially, Nancy Dubuc has been president and CEO of A+E Networks for two days, but she’s already putting her stamp on the company, setting top executives for each of the brands and launching an in-house studio. Under the plan, Bob DeBitetto, General Manager of A&E Networks and BIO, will transition to a new role of head of A+E Studios with a title of President, Brand Strategy, Business Development. He will be succeeded at the helm of A&E by his top lieutenant, David McKillop, EVP Programming, who is adding a general manger title. Dirk Hoogstra, who was promoted to EVP Development and Programming for History and H2 just three months ago, will now add the title of General Manager for the two channels. And as Dubuc moves away from day-to-day oversight of the networks to focus on her role as CEO, Lifetime’s EVP programming Robert Sharenow also is adding general manager responsibilities. Additionally, A+E Networks has officially tapped veteran BBC executive Jana Bennett to run LMN and Bio as president.
