On a night of the conclusion of the CW’s “Crisis On Earth-X” crossover and the This Is Us (2.7/9) winter finale, perhaps the experience of Ming Xi best exemplifies the fate of the 2017 The Victoria’s Secret Fashion Show (1.5/6).

As seen last night on CBS, the model took a big tumble onstage at the Shanghai set show. A stumble that the Fashion Show itself suffered with a new all-time low in the key demo and total viewers. Following a trend that has hit the perhaps anachronistic lingerie supermodel showcase, last night’s VSFS fell 29% from the previous low of last year among adults 18-49. With a scant 4.98 million sets of eyeballs, last night’s Fashion Show was down 25% from the December 5, 2016 show, which was on a Monday and up against the NFL on ESPN.

Or to put all this in another context, while winning its 10 PM time slot, this year’s VSFS was topped in the ratings by an annual broadcast of the Rudolph The Red-Nosed Reindeer (1.8/7) holiday special that the House of Moonves ran at 8 PM.

Sadly, Santa’s bright-beamed pal was also down from last year, with a 22% dimming from its December 1, 2016 airing. A NCIS (1.0/4) repeat bridged the two specials on CBS on Tuesday in the 9 PM slot.

With that, the easy winner for Tuesday was NBC with a 1.9/7 rating and 9.74 million viewers. CBS was in second place with a 1.5/6 rating and an audience of 6.92 million.

On the competitive night, the Comcast-owned net was playing nothing but aces as the unsurprisingly emotionally charged 9 PM winter finale of This Is Us was up 8% in the demo and 16% in viewers to hit a 5-week high with 10.84 million watching. Perhaps also going in the win column for NBC is that this year’s This Is Us winter finale is basically even in both categories with the Season 1 winter finale of the show from December 6, 2016.

Bookending the Dan Fogelman created drama, The Voice (1.8/7) was up a tenth and 10 PM’s Chicago Med was even with its season premiere of last week (1.3/5)

Night 2 of the CW’s Crisis on Earth-X crossover saw The Flash (0.9/4) up a tenth from last week and DC’s Legends Of Tomorrow (0.9/4) surge 80% over its November 21 show to a season high. Compared to last year’s crossover episode, Flash was down 40% while LoT declined 25% from its crossover episode of December 1, 2016, a Thursday. Overall, with 2.75 million tuning in, the CW certainly is feeling no crisis with its most watched Tuesday last night since April 28, 2015.

On Fox there was some happiness too as Lethal Weapon (1.0/4) was even with its November 21 show in the demo but had its most watched episode of the season with 4.95 million viewers. The Mick (0.8/3) and Brooklyn Nine-Nine (0.7/3) were both up a tenth from last week.

ABC was all encores on Tuesday.
