Nancy Dubuc is stepping down as president and CEO of A+E Networks, effective April 16.
She will be replaced temporarily by the company's former CEO, who will oversee all operations until a replacement is named.
"Anyone who knows me well knows I am an entrepreneur, creator, rebel and disruptor at heart. I have a famous neon sign in my office that blares 'Who dares wins,'" said Dubuc in a statement.
"After 20 years at A+E, the hardest thing will be to leave the people and company I love. But, as a creative executive and leader, and to stay true to my personal mantra, I need my next dare and my next challenge."
Dubuc is reportedly in negotiations to take on a leading role in Vice Media, although representatives from both companies have not confirmed the news.
In October 2015, Dubuc oversaw the joint venture agreement with Vice Media that launched the broadcast channel Viceland in February 2016 and led to a 20% stake in Vice Media Holdings, of which she was a member of its board.
Dubic became CEO of A+E Networks in June 2013, overseeing the company's networks, including A&E, Lifetime, History, FYI, Lifetime Movies and Viceland.
She is also responsible for managing digital content and distribution, A+E Studios, A+E Networks International, A&E Indie Films and 45th & Dean.
"In her roughly 20 years at A+E Networks, Nancy played a major role in building the success of A&E, HISTORY and Lifetime, and we thank her for her leadership. We are also very grateful to Abbe, a former CEO of the company and one of A+E’s first employees, for agreeing to return on a temporary basis as acting chair,” added Steven R. Swartz, president and CEO of Hearst, and Ben Sherwood, co-chair of Disney Media Networks and president of Disney|ABC Television, in a joint statement.
"I owe an enormous debt of gratitude to our owners at Hearst and The Walt Disney Company for their unwavering support and belief in me over my long career here. I’d especially like to thank Steve and Ben for supporting my decision to write my next chapter," Dubuc said in her statement.
"I have supreme confidence in the brave storytellers and management team A+E and I will always be rooting for and watching proudly from the sidelines, even as I head off to my next adventure," she concluded.
