A&E Television Networks has reorganized its programming toppers, with A&E Network alum Robert Sharenow becoming exec veep of programming for Lifetime.

David McKillop will shift from History to exec veep of programming for A&E, while Dirk Hoogstra was promoted to senior programming veep for History.

Sharenow had been at A&E as senior VP of programming, where he oversaw development of nonfiction programming for A&E and Bio from conception. During his tenure, A&E’s audience among viewers 25-54 grew every year, with 2010 marking its third straight one in the top five among cablers.

McKillop had been senior veep of development and programming for four years at History, which exhibited similar ratings positives. History also ranked in the top five among cablers in several demos (and first among nonfiction channels), and it launched its 10 most-watched series and six most-watched specials ever in that period.

Hoogstra became vice president of programming and development at History three months after McKillop took his role in 2007, not only working with programmers but also brand-expansion strategies.

Sharenow and Hoogstra will report to Lifetime and History prexy Nancy Dubuc, while McKillop will report to A&E and Bio president Bob DeBitetto. Sharenow fills the top programming post at Lifetime that was vacated last week by JoAnn Alfano, who spent three years at the cabler.

“These three executives exemplify the incredible bench strength we have within AETN. Over the last three years, each of them has played a key role in the double digit growth of our portfolio of brands,” DeBitetto and Dubuc said in a statement.
