Coming off a three-month hiatus, ABC’s Once Upon a Time resumed Season 6 on Sunday night with a hair over 3 million total viewers and a 0.9 demo rating (and an average reader grade of “B+”), hitting and matching its series lows.

Leading out of that, Time After Time debuted to 2.6 mil and a 0.7, with its second hour dipping to 2.5 mil/0.6 — at or below what Secrets and Lies and Quantico most recently did in those time slots. Readers gave the series premiere an average grade of “B.”

Elsewhere….

CBS | NCIS: LA (9.3 mil/1.2) ticked up, while Madam Secretary (7.4 mil/0.8) and Elementary (4.3 mil/0.6) each dipped in the demo while delivering their smallest audiences ever.

NBC | Little Big Shots opened Season 2 with 11.7 mil and a 2.0, on par with its freshman average and dominating the night. Chicago Justice (7.3 mil/1.4) was down from its crossover launch (8.7 mil/1.7) but placed second in the demo for the night. Shades of Blue (5.2 mil/1.0) ticked down from its finale/freshman average.

FOX | Making History premiered to 2.2 mil and a 0.9 (and a grade of “B+”), improving on time slot predecessor Son of Zorn‘s most recent numbers. Leading out of that, Family Guy (2.5 mil/1.2) rose two tenths and Last Man on Earth (2.2 mil/1.0) was up a tenth from its midseason finale. The Simpsons (2.6 mil/1.1) was steady.

As always and forever, cable ratings (e.g. FX’s FEUD) come in much, much later and as merited are reported under separate cover.Want scoop on any of the above shows? Email InsideLine@tvline.com and your question may be answered via Matt’s Inside Line.
