Supergirl season premiere scores best CW time slot ratings in almost a decade

Moving Supergirl from CBS to The CW was an interesting experiment, but the big question was how the series would be received at its new home. Turns out a good bit of those CBS fans followed Kara to The Flash’s stomping grounds.

According to The Hollywood Reporter, the Season 2 premiere of Supergirl scored 3 million viewers and a 1.1 rating among adults 18-49. Of course, that’s still about half as many total viewers as the show pulled in at CBS (which isn’t a surprise, because CBS is way bigger than The CW), but its just two-tenths of a point down in the key demo. Compared to the Season 1 finale at CBS, the Season 2 premiere actually increased its 18-34 viewership (the key advertising demo) by 29 percent.

The CW opted to keep Supergirl on the same Monday night timeslot it inhabited at CBS, and the premiere was the most-watched thing the network has aired in that time slot in eight years (you have to go back to Gossip Girl’s glory days for when that record was set). That’s huge for The CW, and gives the network a successful foothold on an extremely competitive night.

The network will almost certainly be pleased with the numbers, especially for the timeslot. For the sake of comparison, Flash’s Season 3 premiere edged Supergirl with 3.2 million total viewers and a 1.3 demo rating. That’s not much of a surprise (Flash is one of the network’s biggest hits ever), and putting Supergirl on that level certainly bodes well for the series' chances.

The big worry, though, is Arrow. The Season 5 premiere dipped to 1.9 million total viewers and a .7 rating in the 18-49 demographic. That’s down nearly 30 percent compared to last season. It’s still above a lot of the network’s non-superhero fare, but Arrow is also more expensive to make. So if the numbers keep sliding this season, it could theoretically reach a point where the show isn’t financially feasible. 

Are you glad to see Supergirl turn out to be a hit? What’d you think of the premiere?
