At TCA today, Showtime entertainment president David Nevins laid out the pay cable network’s scheduling plans for the rest of 2013. The biggest change is the decision to separate veteran Dexter and Homeland, which have been paired since Homeland‘s launch in fall 2011, helping both shows break ratings records. “Dexter has proved incredibly valuable as a launch pad for Homeland,” Nevins said. “Our plan is to harness (the success) and use the shows to launch the next generation of Showtime drama series.”

Dexter will get on the air earlier than usual, on June 30 at 9 PM, serving as a lead-in for new crime drama Ray Donovan. The early return has not affected production on Dexter. “There is no less production time, just a little less vacation time between the seasons,” Nevins dais, adding that the drama’s producers and cast had gotten enough lead time to adjust to the scheduling change.

On Sept. 29, “we are employing our crown jewel Homeland to launch Masters Of Sex,” Showtime’s new drama about real-life pioneers of the science of human sexuality, William Masters and Virginia Johnson, Nevins said.
