CBS Entertainment’s Bryan Seabury has been named head of drama development for CBS Television Studios. He takes over for Julie McNamara, who on Monday was made head of original content for CBS All Access.

As senior vice president of drama, Seabury will report to CBS Television Studios president David Stapf. Seabury had previously served as senior vice president of drama development at CBS Entertainment.

“I’ve worked with Bryan for nearly 10 years at both the Network and Studio. His exceptional creativity and dedication make him one of the most respected and trusted executives in the industry,” said Stapf. “In addition to his creative talent, he’s worked on both the buying and selling side, providing great perspective to all the key constituents we produce for.”

The move marks a return for Seabury, who began his tenure at CBS with the studio. He spent the last seven years on the network side, helping to develop “Madam Secretary,” “NCIS: New Orleans,” “Scorpion,” “Elementary,” “Hawaii Five-0” and “Blue Bloods.”

Previously, as vice president of drama for the studio, he worked on “The Good Wife” and “NCIS: Los Angeles” for CBS as well as The CW’s “90210,” “Melrose Place” and “Life Unexpected” for the CW.

Before joining CBS, he was vice president of TV development at Mark Johnson’s Gran Via Productions.

CBS is the third television studio to reshuffle its executive deck in recent weeks. Last month, Bela Bajaria departed as president of Universal Television, replaced by Pearlena Igbokwe. Two weeks ago, chairman Steve Mosko left Sony Pictures Television, which realigned its executive structure under Zack Van Amburg and Jamie Erlicht.
