Ratings: Once Upon a Time Steady, Pan Am Up, Allen Gregory Gets Low Grades

ABC’s Once Upon a Time continued to work its magic this Sunday, delivering 11.64 million total viewers with its second episode while scoring a 3.9 rating (down just 4 percent in the demo from its series debut).

In turn, Desperate Housewives upticked a bit (to 9.3 mil/3.0) and even Pan Am (5.6 mil/1.9) gained 6 percent in the demo.

Elsewhere for the night:

* The Simpsons‘ annual “Treehouse of Horror” (8 mil/4.0) served up a ratings treat, gaining 33 percent from the show’s last fresh outing and marking its best demo since Jan. 9. New lead-out Allen Gregory, though, dismissed 40 percent of that audience in its debut.

* NBC’s Sunday Night Football (20.2 mil/8.2) surged some 60 percent from last week’s blowout.

* CBS’ numbers are scrambled for now, due to delayed starts, but my best guesstimation shows that Amazing Race was up a bit, The Good Wife was flat (meaning it matched a season-low demo), and CSI: Miami dipped a little.

Because someone will always ask: “Cable ratings come in much, much later.”
