Television ratings aren’t always the most exciting topic to discuss. Generally, fans tend to like what they like and just hope the ratings stay solid enough to avoid cancellation. Occasionally, though, when ratings are so abnormal they end up breaking records, it’s worth discussing. And breaking records is exactly what The Flash and Supergirl did this week — although it was in opposite directions.

Supergirl Hits 8-Year High

It was widely expected that Supergirl would be a ratings success for The CW. The network’s president, Mark Pedowitz, even said earlier this summer he anticipated the show becoming the show’s second most-watched show, at the least.

As it turns out, he may have been underestimating the Girl of Steel. Over 3 million viewers tuned in for the Supergirl season premiere on Monday. It was the highest viewership The CW has seen in that timeslot since an episode of Gossip Girl in 2008. Supergirl also got a 1.1 score in the coveted 18-49 demographic. The CW hasn’t seen a score that high in this timeslot since an episode of 90210 six years ago.

It’s not terribly surprising that Supergirl performed so well. In its first season, the show aired on CBS — a network with a much higher viewership than The CW. So while everyone who watched the show on CBS last year will likely not migrate over the The CW, even a fraction of those viewers was bound to make a mark. In fact, the Season 1 finale on CBS was watched by over 6 million views. So Supergirl managed to set a record on The CW will only half the number of viewers it had last May.

'The Flash' Unveils New Logo for Season 4

The Flash Falls to its Lowest Level

Unfortunately, things are not looking quite so sunny over on The Flash. The season’s second episode, ‘Paradox,’ produced a record low rating for the entire series. Only 2.75 million viewers tuned in for this week’s episode.

Season 3 of The Flash actually started off with viewership down. 3.1 million viewers tuned in last week for the season premiere, ‘Flashpoint.’ That’s down from the 3.6 million viewers the Season 2 premiere garnered last year.

No one knows for sure why The Flash‘s ratings have dipped. There has been some vocal fan backlash against Barry’s actions in the Season 3 finale, but most fans seemed genuinely excited by the Flashpoint storyline. There’s still plenty of time for things to level off, and the upcoming crossover episodes should give a boost to the ratings for all four shows.
