More like “This Is Unstoppable”: NBC’s “This Is Us” is no longer just a bona fide hit, it’s turning into a shining beacon for the network. In the usually dark doldrums of November, the Dan Fogelman drama drew a 2.7 rating in the advertiser-coveted 18-49 demographic and 10.56 million viewers in Nielsen’s preliminary ratings for Tuesday, the show’s biggest total audience yet and a mere tenth below the series high in the demo. Lead-in “The Voice” pulled in a low 1.9 in the demo and 10.6 million viewers, but “This Is Us” helped boost lead-out “Chicago Fire” from the previous week in the demo, with a 1.7 and 8.02 million viewers.

Don’t sleep on CBS’ annual broadcast of “Rudolph the Red-Nosed Reindeer,” though. The 8 p.m. telecast beat out “The Voice” in the 18-49 and 18-34 demos, with a 2.3 in the 18-49 demo. “Rudolph” also pulled in 9.45 million viewers. CBS was in repeats the rest of the night.

On The CW, the second night of the net’s big DC crossover event went swimmingly, with “The Flash” drawing a plump 1.5 in the demo and 4.09 million viewers, its best performance in the demo since last season. “No Tomorrow” ticked up slightly from the week before with a 0.4 in the demo and 1.07 million viewers.

ABC’s comedy block hovered around its usual performance. “The Middle” began the night with a 1.6 and 6.6 million viewers. “American Housewife” followed with a 1.4 and 5.57 million viewers. “Fresh Off the Boat” drew a 1.2 and 4.19 million viewers. “The Real O’Neals” capped off the comedy portion of the evening with a 1.0 and 3.33 million viewers. “Agents of S.H.I.E.L.D.” returned after a month-long break with a 0.8 and just 2.51 million viewers.

Fox’s “Brooklyn Nine-Nine” ticked up from last week with a 1.0 and 2.36 million viewers, while “New Girl” stayed low with a 0.8 and 1.86 million viewers. “Scream Queens” also stayed low with a 0.5 in the demo and 1.34 million viewers.

As a reminder, many of these shows will see ratings lifts of 50% or more once viewing done within three and seven days is counted. However, most of those gains won’t translate to the ratings guarantees networks make advertisers.
