Fox’s two-hour special of “American Idol” did nothing-special numbers Tuesday opposite NBC’s coverage of the Sochi Winter Olympics, which itself posted some of its softest weeknight ratings to date.

According to preliminary national estimates from Nielsen, Olympics action that included women’s alpine skiing, men’s freestyle skiing and women’s short track averaged a 4.8 rating/14 share in adults 18-49 and 18.5 million viewers overall during primetime. This is down a little over 10% in both categories from the comparable night in Vancouver four years ago.

The previous low in viewership for any weeknight thus far was the 19.11 million who watched last Friday. Overall, these Olympics are tracking 14% lower in 18-49 (5.9 vs. 6.9) and 10% lower in total viewers (18.5 million vs. 21.2 million).

Still, NBC crushed the competition once again, with Fox’s special two-hour “American Idol” (2.7/8 in 18-49, 9.6 million viewers overall) the only broadcast offering to offer much of a distraction for viewers.

Univision moved up to third place in 18-49 on the night, led by “Lo Que la Vida Me Robo” at 9 (1.6/4 in 18-49, 3.8 million viewers overall) and “Que Pobres Tan Ricos” (1.4/4 in 18-49, 3.1 million viewers overall) at 10.

CBS aired reruns of dramas “NCIS” (1.3/4 in 18-49, 9.8 million viewers overall), “NCIS: Los Angeles” (1.4/4 in 18-49, 8.0 million viewers overall) and “Person of Interest” (1.1/3 in 18-49, 6.4 million viewers overall).

ABC went with encores of “Marvel’s Agents of SHIELD” (0.8/2 in 18-49, 2.7 million viewers overall), “The Goldbergs” (0.7/2 in 18-49, 2.5 million viewers overall) and “Trophy Wife” (0.7/2) and the firstrun finale of drama “Killer Women” (0.6/2 in 18-49, 3.2 million viewers overall).

CW aired special repeats of Thursday drama “The Vampire Diaries” (0.3/1 in 18-49, 0.8 million viewers overall) and new Monday drama “Star-Crossed” (0.3/1 in 18-49, 1.0 million viewers overall), the latter of which drew nearly the same numbers it did for its premiere one night earlier.

Preliminary 18-49 averages for the night: NBC, 4.8/14; Fox, 2.7/8; Univision, 1.4/4; CBS, 1.3/4; ABC, 0.7/2; Telemundo, 0.4/2; CW, 0.3/1.

In total viewers: NBC, 18.5 million; Fox, 9.6 million; CBS, 8.1 million; Univision, 3.2 million; ABC, 2.7 million; Telemundo, 1.2 million; CW, 0.9 million.
