Although Big Brother rules the roost three times a week, CBS can’t run reality programming every night during the summer. Despite low ratings for a Tiffany Network TV series, James Patterson’s drama Zoo is currently in its third season. Now they’ve launched the Salvation TV show. Can it live up to its name? Will Salvation be cancelled or renewed for season two? Stay tuned.

A CBS suspense drama, Salvation, stars Santiago Cabrera, Jennifer Finnigan, Charlie Rowe, Jacqueline Byers, Rachel Drance, Shazi Raja, and Ian Anthony Dale. The thriller follows MIT graduate student Liam Cole (Rowe) and tech genius Darius Tanz (Cabrera). Because they don’t want to cause public panic, the two present Pentagon Press Secretary, Grace Barrows (Finnigan), with evidence that in six months, a huge asteroid will crash into the Earth.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly in 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.

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.

What do you think? Do you like the Salvation TV series? Should it be cancelled or renewed for a second season on CBS?
