Showtime programming chief David Nevins has been promoted to president of Showtime Networks and extended his contract with CBS Corp.'s pay cabler through 2018.

With the new post, Nevins takes on oversight of Showtime's sports division as well as marketing, creative and digital media operations. He continues to report to Showtime Networks chairman-CEO Matthew Blank.

Nevins, a former Fox and NBC programming exec, came to Showtime in mid-2010 after eight years as president of Imagine Television. On his watch, Showtime has reached new heights with the success of "Homeland" -- the first show that Nevins greenlit and the first Showtime series to win the Emmy for best drama.

Among the other successful series he's shepherded are dramas "Ray Donovan" and "Masters of Sex" and comedy "House of Lies." He's also spearheaded Showtime's push into the documentary world with such recent entries as R.J. Cutler's "The World According to Dick Cheney" and Marina Zenovich's "Richard Pryor: Omit the Logic."

Nevins' "arrival at Showtime was followed by an incredible period of renewal for our Network, and these transformative years have led to critical-acclaim, consistent buzz, subscriber growth and awards recognition," Blank said in announcing the promotion.

After delivering a new wave of signature series for the cabler, Nevins is known to be a favored lieutenant of CBS Corp. prexy-CEO Leslie Moonves.

In January, Nevins gave greenlights to two drama series, "Happyish" and "The Affair." The fate of "Happyish" was thrown into turmoil when star Philip Seymour Hoffman died of a drug overdose last month. It remains uncertain whether the role will be recast or if the drama about a forty-something man grappling with aging will be tabled.

Also coming up on Showtime's slate this year is "Penny Dreadful," a horror drama from Sam Mandes and John Logan.
