Peter Byrne, who helped launch 20th Century Fox’s powerful licensing and merchandising department, is ankling the studio.

Byrne spent the past four years as exec VP of licensing and merchandising at 20th Century Fox, where he oversaw both film and TV properties.

A replacement will be named shortly.

Byrne had overseen “The Simpsons” merchandising since joining the studio in December 1997, starting in Europe and then moving to L.A. in 2001 to expand the studio’s licensing and merchandising program in the U.S.

Most recently, Byrne’s division oversaw the theatrical merchandise campaign for animated feature “Robots,” as well as the campaign for “Napoleon Dynamite.”

Byrne also helped relaunch 20th Century Fox’s “Family Guy” merchandising, timed to the rebirth of the show on Fox. His credits include the launch of the studio’s classic Fox Film Icons library.

“I’ve come full circle in terms of everything I can do at Fox,” Byrne said. “From a small beginning, we became a powerhouse licensing brand across the globe.”

Byrne joined 20th Century Fox from Sara Lee; he also spent 10 years in the toy industry, working at both Kenner and Matchbox.
