Both shows received 12-episode orders and will premiere in 2013.

"Ray Donovan and Masters of Sex, each in their own distinctive ways, represent the caliber of programming we want to bring to our subscribers," David Nevins, Showtime's entertainment president, said in a statement. "Both series are ambitious and expansive, and feature great writing and great acting. I'm so excited for viewers to experience these two new dramas, which I believe will prove to be fantastic complements to our current slate of programming."
