TV Ratings: ‘Supergirl’ Jolted by ‘Flash’ Crossover

A rare network crossover episode, which put the star of CW hit The Flash on Monday’s outing of CBS’ Supergirl, scored a big bump for the latter. Supergirl rose 30 percent in the key demo for its best showing in over a month, averaging a 1.7 rating with adults 18-49 and 7.2 million viewers.

But the night belonged to The Voice. Even with last Monday, the NBC series averaged a dominant 2.8 rating among adults 18-49. Blindspot was steady, earning a 1.6 rating in the key demo to secure a nightly win for NBC.

Dancing With the Stars, slightly humbled from last week’s premiere, averaged a 1.7 rating among adults 18-49. It managed to win the night among total viewers with 11.8 million.

ABC also is hoping to drum up more eyeballs for The Catch after Thursday’s modest premiere. The latest Shonda Rhimes production, which grew to a 1.9 rating among adults 18-49 in live-plus-three day ratings, earned a respectable 0.7 rating in the key demo during a Monday repeat.

After Supergirl, CBS posted steady outings of Scorpion (1.6 adults) and NCIS: Los Angeles (1.2 adults). And on Fox, Gotham (1.3 adults) and Lucifer (1.2 adults) also held.

The CW saw modest growth for both Crazy Ex-Girlfriend and Jane the Virgin, which averaged a 0.3 and 0.4 rating, respectively, among adults 18-49.
