A pattern has emerged in the ratings race this fall, with NBC the leader among young adults but CBS challenging in the weeks when it gets help from football spilling into primetime on Sunday.

Last week saw the Eye — whose “The Big Bang Theory” remains scorching hot — tie NBC in 18-49 while pulling ahead in adults 25-54 and dominating as usual among total viewers. NBC has held at least a share of the weekly 18-49 crown for nine of the season’s first 10 weeks, while CBS has won outright in 25-54 for two of the last three weeks.

Cable had a big week, including AMC’s “The Walking Dead,” Discovery’s “Gold Rush” and ABC Family with its holiday fare.

Overall, according to Nielsen estimates for Nov. 26-Dec. 2, CBS and NBC tied in 18-49 with a 2.6 rating/7 share, and were followed by ABC (2.1/6), Fox (1.8/5) and Univision (1.6/4). The Eye led by 1 share in 25-54 (3.6/9 to 3.2/8 for NBC) and by more than 3 million total viewers (11.4 million to 8.0 million).

CBS had a strong Monday, as a special repeat of “The Big Bang Theory” at 8:30 p.m. (former slot of the canceled “Partners”) seemed to lift the entire night: “2 Broke Girls” (4.1/10, 11.74m), “Mike & Molly” (3.6/9, 11.29m) and “Hawaii Five-0” (2.3/6, 10.30m) all hit season highs.

Also for the Eye, “The Amazing Race” hit highs (2.7/6, 10.02m) and “Criminal Minds” (2.9/8, 12.37m) drew its largest aud of the fall. And auds didn’t take Angus T. Jones’ advice and turn off “Two and a Half Men,” as his show dominated its Thursday slot (4.0/11, 13.74m).

At NBC, Monday popped with gains for “The Voice” (4.2/11 in 18-49, 12.17m) and “Revolution” (2.9/8, 8.54m), with the latter airing its last seg until early spring. Wednesday surged too with specs “Christmas in Rockefeller Center” (2.1/6, 9.14m) and “SNL Christmas” (2.7/7, 7.36m).

And of course, “Sunday Night Football” ruled as the week’s No. 1 primetime show (7.4/18, 20.42m).

ABC was led by “Modern Family” (4.7/12, 12.01m) and dramas “Grey’s Anatomy” (3.1/8,. 8.95m) and “Once Upon a Time” (3.1/8, 9.10m) and also got a lift from holiday fave “A Charlie Brown Christmas” (2.9/8, 8.85m). “Dancing With the Stars” hit a season high with its finale (3.0/8, 16.73m) but it was off 27% from a year ago.

Fox saw its Tuesday comedy lineup — including rookies “Ben and Kate” (1.4/4, 2.82m) and “The Mindy Project” (1.5/4, 2.76m) — join Wednesday’s “The X Factor” (2.9/8, 8.20m) as showing nice gains vs. the previous week.

Univision outdelivered at least one of the Big Four in 18-49 on four nights and led them all on Friday. Season to date, the Spanish-language net’s 1.5 rating/4 share in 18-49 is nearly double CW (0.8/2).

CW continues to do well with vet “The Vampire Diaries” (1.4/4 in 18-49, 2.86m) and rookie “Arrow” (1.3/4, 3.74m) but could use help in most other timeslots.

In cable, AMC’s “The Walking Dead” (5.4/12 in 18-49, 10.48m) headed into its midseason break by posting its second best scores to date and finishing closely behind “Big Bang Theory” as the week’s top entertainment series in 18-49. Discovery’s “Jungle Gold” (1.9/6, 4.59m) was TV’s No. 1 show in 18-49 on Friday and hitting a season high in adults 25-54 (2.2/7).

ABC Family ran second among cablers in 18-49 (behind ESPN) with its “25 Days of Christmas,” including Sunday’s “Dr. Seuss’ How the Grinch Stole Christmas” (2.1/5, 5.47m), cable’s No. 1 TV movie of the year in younger demos.

Bravo’s “Shahs of Sunset” opened its second season with series highs Sunday (1.1/3, 2.30m), and Investigation Discovery (ID)’s “Homicide Hunter: Lt. Joe Kenda” moved above 1 million viewers Tuesday (1.08m) to become one of the net’s top telecasts of all time.
