AETN makes the expected official: the programmer is staying inside when it comes to a successor for Andrea Wong as head of Lifetime. Nancy Dubuc, president of the History brands, adds president and GM of Lifetime effective May 1. Dubuc was considered a strong candidate to replace Wong, whose departure was announced in early February. Dubuc already has a good relationship with AETN CEO Abbe Raven and a track record of bringing hit series and specials to History (Ice Road Truckers, The Universe) during her three years there. The news comes the day after History announced a ratings record with America The Story of Us. She earned her way to History with a record of strong programming for A&E after she joined in 2003.
