As president of entertainment and media at A&E Networks just since last September but president and general manager of History and Lifetime before that, Ms. Dubuc has been credited with turning History from the "Hitler channel," as it was previously dubbed for its reliance on World War II documentaries, into a top-five cable network among adults 18-to-49, with reality fare like "Pawn Stars" and "Swamp People."
She was also responsible for the revival of Lifetime, recent hits like A&E's "Duck Dynasty" and History's first scripted drama ("Vikings") and miniseries ("The Bible").
Ms. Dubuc will report to Ms. Raven and the board of directors.
Ms. Raven oversaw A&E's merger with Lifetime in 2009. In her new role, the company said, she will oversee A&E Networks' long-term business and revenue opportunities, as well as public policy initiatives, and serve as corporate strategic advisor, reporting to the board of directors.
