Last season, Supergirl aired on CBS but the ratings weren’t strong enough for it to stay on the network. The TV show’s now moved to The CW. Will many viewers follow the superhero series? Will it be a hit in the ratings on the smaller network — even though the numbers will be much lower? Cancelled or renewed for season three? Stay tuned.

Supergirl revolves around Superman’s cousin, Kara Zor-El (Melissa Benoist). As a girl, she survived Krypton’s destruction by being sent to Earth where she was raised as a human. She kept her powers a secret and now, as an adult, works as an assistant at a big city media conglomerate. Kara’s existence becomes known to the world and she is enlisted by a super-secret agency to help protect the citizens from evil forces as Supergirl. The rest of the cast includes Mehcad Brooks, Chyler Leigh, Jeremy Jordan, David Harewood, Floriana Lima, and Chris Wood. Recurring actors this season include Calista Flockhart, Ian Gomez, Katie McGrath, Lynda Carter, Brenda Strong, and Tyler Hoechlin.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly the 18-49 demo), the better the chances for survival. This chart will be updated as new ratings data becomes available — usually the next day, around 11:30am EST/8:30am PST. Refresh to see the latest.

For comparisons: The first season of Supergirl on CBS averaged a 1.68 rating in the 18-49 demographic with 7.68 million total viewers (Live+SD).

Note: These are the Live + Same Day Ratings which include “live” viewing plus delayed DVR viewing, up until 3am local time that same night. Ratings marked with an “*” are the fast affiliate ratings and will be updated with the Live+SD numbers when they are made available. Typically, networks get paid for C+3 ratings which includes DVR viewing within three days of the original airing when commercials are watched. Those numbers are rarely released to the press.
