"Homeland continues to prove its strength for Showtime, and is one of television's most exciting, provocative and widely-discussed shows.  It has grown its audience significantly in each of its three seasons," Showtime's President of Entertainment, David Nevins, said in a statement. "The critical and audience reaction to Masters of Sex since its great launch has been incredibly gratifying.  It's a privilege to get to work with such talented and creative people as Alex Gansa and Michelle Ashford, as well as their tremendous casts.  They have each created truly original shows, with distinctive voices that are among the most admired series on television."

Both series will return in 2014 with 12 episodes each.
