Nancy Dubuc‘s meteoric rise continues. Seven months after she was named President, Entertainment and Media, A+E Networks, taking creative oversight of the entire cable group, Dubuc has now been named president and CEO of A+E Networks. She succeeds Abbe Raven, who is being elevated to Chairman, A+E Networks. The promotions come as A+E networks continue to deliver blockbuster ratings, most recently with History’s The Bible and Vikings and A&E’s Duck Dynasty.

Effective June 1, 2013, Dubuc will oversee the day-to-day operations of the company with the brand groups and business divisions reporting to her. Raven will be in charge of A+E Networks’ long-term business and revenue opportunities, as well as public policy initiatives, and serve as corporate strategic adviser. Raven will report directly to the company’s Board led by Anne Sweeney, president, Disney/ABC Television Group, and Steven Swartz, president & COO, Hearst Corp. Dubuc will report both to Raven and the Board. “Abbe and Nancy have enjoyed one of the most successful partnerships in our business. Together, over the last several years, they have built some of the strongest brands in media, Sweeney and Swartz said jointly. “We look forward to the company’s next chapter as Abbe becomes chairman and Nancy steps into her expanded new role as president and CEO and leads the company into the future”.

The promotions, which had been expected, mark a natural progression for Dubuc and Raven, who had taken Dubuc under her wing since she was a young executive at the company. “A+E Networks’ culture has always been about rewarding success and encouraging innovation”, Raven said. “Nancy is one of the most talented executives working in media today—a decisive leader, with her hallmark drive and determination”. Said Dubuc, “Abbe has been a great mentor and partner for over 10 years. She created a corporate culture at A+E Networks where creativity thrives and as a result we cultivated some of the most powerful global brands in media”.

In her most recent role as President, Entertainment and Media, A+E Networks, Dubuc oversaw all content creation, brand development and marketing for the entire A+E Networks’ portfolio. While there likely won’t be a direct replacement, Dubuc will likely install an executive with an bird-eye view of all brands in the coming months. In 2013, A+E Networks leads all other cable groups with 10 of the top 25 shows in adults 25-54 and 18 of the top 50 shows in adults 25-54; including the #1 nonfiction show Duck Dynasty, the #1 new drama series Vikings and the #1 miniseries The Bible. Raven, who started at the company 30 years ago picking up the phones, has led A+E Networks as President and CEO since 2005, tripling its earnings and expanding its global portfolio. She oversaw the 2009 merger with Lifetime. A+E Networks now encompasses more than a dozen divisions, including A&E Network, History, Lifetime, LMN and Bio, reaching more than 350 million households in over 150 countries.
