After three years spent largely heading up Cartoon Network’s foray into live-action programming, VP of original series Rob Swartz has left the network. Friday was his last day at the L.A.-based studio.

On the heels of Swartz’s departure, VPs Nick Weidenfeld and Tramm Wigzell, who head up development at the comedy and action groups, respectively, are now reporting directly to chief content officer Rob Sorcher. Curtis Lelash, meanwhile, is looking after comedy animation development for kids, and all current animated series production, working under Weidenfeld.

For his part, Swartz is returning to his roots in alternative series creation as an independent producer. Before moving over to CN, Swartz was VP of alternative programming at US cablenet SyFy, where he oversaw the Ghost Hunters franchise.
