EXCLUSIVE: Modern Family executive producer Dan O’Shannon will be leaving the Emmy-winning comedy series at the end of this season for a three-year overall deal at CBS TV Studios. Under the pact, he will develop new comedy projects for network and cable. This marks a return to CBS TV Studios for O’Shannon, who was under an overall deal at predecessor Paramount TV more than a decade ago. Back then, he served as executive producer/showunner of the studio’s flagship comedy Frasier having previously spent four seasons as a writer and, later, exec producer on mothership series Cheers.

O’Shannon has been on ABC/20th TV’s Modern Family since after the pilot, joining as a co-executive producer and serving as an executive producer for the past three seasons. He has shared in Modern Family‘s four consecutive best comedy series Emmy wins and has been part of five other best comedy series noms and one win for Cheers and Frasier.

O’Shannon, repped by CAA and Jamie Mandelbaum, is one of several Modern Family executive producers whose deals are coming up this season. Danny Zuker and Paul Corrigan & Brad Walsh recently re-signed with 20th TV, while Bill Wrubel is moving to Warner Bros TV with a three-year overall deal.
