UPDATED: Coming in January, all of Showtime’s original series will run on one night, Sunday. Back in July, Showtime announced that new drama Shameless will debut on Jan. 9 and air in the Sunday 10 PM slot. Returning comedy Californication and new half-hour Episodes were scheduled to premiere Jan. 10 and air on Mondays at 10 PM and 10:30 PM, respectively. Now new entertainment president David Nevins has tweaked the plan, putting all 3 series on Sundays: Californication at 9 PM, leading into Episodes and drama Shameless. All will premiere on Jan. 9.
