The premiere of CBS drama Supergirl posted solid, not spectacular Live+3 gains: +3.17 million viewers (+24%) to 16.13 million,  and +0.99 in adults 18-49 (+32%) to 4.1 rating. That was below the lifts fellow rookie Monday drama, NBC’s Blindspot, got for its debut (+4.59 million viewers, +43%; 1.34 18-49 rating. +43%).

Supergirl had enough Live+same day cushion in Live+same day to remain the season’s #1 series premiere in viewers in L+3. Among adults 18-49, the Supergirl and Blindspot premieres finished tied in Live+same day with a 3.1 rating, the highest for a new series this fall. In Live+3, Blindspot moved ahead with a 4.5 ratings vs. 4.1 for Supergirl, which is ranking as No.2 among all new programs in the demo.

For this past Monday, Supergirl‘s 18-49 lift of a 1.34 rating was third highest behind CBS’ The Big Bang Theory (1.62 rating to 6.0, +62%) and Blindspot (1.34 rating to 3.5, +62%).
