EXCLUSIVE: After a decade at Fox, EVP current programming Marcy Ross is leaving the network. Ross’ three-year contract is up this year and I hear she opted not to renew it and plans to return to content creation. I hear Ross, a well-liked executive, is already pursuing other opportunities but will remain at Fox in a consulting capacity for the transition, likely through the end of the season. Fox wouldn’t comment on the reasons for Ross’ exit but I hear she and top network brass have had differences. Ross was brought to Fox in 2002 by then-entertainment president Gail Berman with whom Ross had previously worked at Sandollar TV where they developed Buffy The Vampire Slayer. After a five-year stint as SVP current programming at Fox, Ross was upped to EVP in 2007. She has led the network team that oversees all new and returning scripted series, including newcomer The Following, veterans Bones, Family Guy and The Simpsons as well as American Dad, Glee, New Girl, Raising Hope and Touch. In the interim, Fox’s current series will be overseen by Shana C. Waterman and James Oh, who have been working under Ross. Ross came to Fox from Studios USA, where she was SVP comedy programming and also did a stint at The Jim Henson Co. as SVP creative affairs.
