He will remain aboard the net as it searches for his replacement.
News arrives as Riley’s contract nears its expiration. Riley joined the net three years ago after former chief Paul Lee transitioned to the broadcast sector to lead the ABC.
Before his tenure at ABC Family, Riley served as general manager of Radio Disney, and logged years working with Turner Broadcasting’s international divisions. He has spent six years in the Disney family.
“Michael has been a great leader over the past six years at Radio Disney and ABC Family, and his contributions will be felt for years to come,” said Anne Sweeney, prexy of Disney-ABC Television Group. “While we understand and support his decision to leave, it will be sad to see him go. We wish him the best of luck on his next adventure.”
Under Riley’s leadership, ABC Family has seen an increase in original content, particularly during summer months. Series including “Pretty Little Liars,” which launched shortly before Riley’s appointment to the top programming post, reign as some of the most social shows on TV thanks to a Twitter-hungry younger demographic base. Furthermore, frosh programs “The Fosters” and “Twisted” debuted strongly on the net, ranking as some of the top cable series in their time periods this summer.
