Showtime has promoted Gary Levine to president of programming.

Levine joined the CBS-owned network 14 years ago as executive VP of original programming. In the new role, Levine will continue to lead development and creative oversight of Showtime’s scripted and unscripted series, documentaries and specials. He will now also oversee casting and operations.

He continues to report to president David Nevins, who will become CEO in January.

Documentaries Levine has worked on for Showtime include Listen to Me Marlon, Prophet’s Prey and the Emmy-winning series Years of Living Dangerously. He has also made the network a hotbed for scripted programming through titles such as Weeds, Homeland, Nurse Jackie, Dexter and Masters of Sex, among others.

“Gary has proven to be an invaluable creative partner to me since the day I arrived at Showtime,” said Nevins, who joined the network in 2010. “I am confident that in his expanded role he will lead our programming team to outstanding new heights.”

Prior to joining Showtime, Levine was the president of Internet entertainment company Icebox and headed development at Warner Brothers Television, Witt-Thomas Productions and ABC’s drama department. His credits include The West Wing, Blossom and Twin Peaks, which Showtime is reviving as a limited series with director David Lynch.
