"Glee" alum Melissa Benoist stars as CBS's Supergirl.
"Supergirl" just soared above the competition. The new CBS series is now the season's most-watched premiere.
It premiered Monday night to record numbers for the season: 12.9 million viewers and a huge 3.2 rating among the advertiser-coveted 18 to 49-year-old audience, according to a CBS news release.
That means "Supergirl" beat CBS comedy "Life in Pieces" (11.3 million viewers) for most viewers and NBC's "Blindspot" (3.1 rating) for bigger 18-49 rating.
"Supergirl" clearly benefitted from its "Big Bang Theory" lead-in. The comedys is TV's most-watched show and currently averages 15.72 million viewers.
The series moves to its regular time - Mondays at 8 p.m. - starting next week, so it remains to be seen how much of its audience it will retain after seeing the pilot and without the "Big Bang" lead.
