Longtime “CSI” showrunner Carol Mendelsohn has set a new overall deal at Sony Pictures TV.

Mendelsohn is relocating her shingle to the Culver City lot from CBS TV Studios, where she has been based since the dawn of “CSI.” She is bowing out of her day-to-day role as showrunner for the first since the forensic drama that spawned a global franchise premiered in 2000.

The three-year pact calls for Carol Mendelsohn Prods. to develop projects across the spectrum of network, cable and digital outlets. CMP prexy Julie Weitz will make the move with Mendelsohn.

Sony TV has made a point of recruiting heavy-hitter showrunners during the past few years, and bringing Mendelsohn over from the Eye is a coup for the studio. Sony Pictures TV programming and production chiefs Jamie Erlicht and Zack Van Amburg had the highest praise for the well-regarded showrunner, who learned the craft from masters such as Stephen J. Cannell and Aaron Spelling.

“Carol is a part of the fabric of television around the world and to work with someone who has not only created but sustains such an amazing global franchise is an honor,” said Van Amburg. “With her ability to tell stories that engage audiences everywhere, and the array of opportunities for great content, there is no limit to what we can accomplish together,” added Erlicht.

Mendelsohn has worked outside of the “CSI” universe in recent years, fielding shows for CBS (“The Defenders,” “Dogs in the City”) and development projects at Showtime, TNT, FX and other outlets.

Mendelsohn is repped by WME and Jackoway Tyerman Wertheimer.
