Supergirl will remain airborne through (at least) Spring 2016.
CBS on Monday ordered an additional seven episodes of Greg Berlanti’s super-fun DC drama, bringing its Season 1 total to 20 episodes. Although that’s technically two episodes shy of a traditional full-season order, CBS is calling it a “full season” pickup.
Supergirl premiered in October with 13 million viewers and a 3.1 rating, tying NBC’s Blindspot as this fall’s biggest freshman launch. The show’s numbers have since fallen to Earth, with its most recent episode drawing a series-low 7.2 million/1.5 rating.
CBS notes that Supergirl has improved the year ago time period by 46 percent in viewers and 40 percent in adults 18-49.
