Survivor bounced back from a season low in Wednesday's ratings, while Empire and Riverdale also improved on their last outings. NBC's Christmas in Rockefeller Center, however, fell compared with its 2017 edition.

A two-hour Survivor posted a 1.6 rating among adults 18-49 on CBS, up from a 1.3 for last week's Thanksgiving Eve installment. The 1.6 ties the show's second-best demo rating of the season.

Empire returned from a week off to a 1.5 on Fox, up a tick from its last airing in both the demo and in total viewers (5.05 million). Star held steady at 1.1 for adults 18-49.

Christmas in Rockefeller Center was the night's most watched show, with 8.38 million viewers, but both that and its 1.3 in the demo are down compared with a year ago (9.03 million, 1.7). A Legendary Christmas With John and Chrissy scored a 0.8 at 10 p.m.

Riverdale tied its season high in the 18-49 demo at 0.5 on The CW. All American was steady at 0.3.

ABC's comedies all returned slightly lower for adults 18-49 after two weeks off, but A Million Little Things (0.8) improved by a tenth of a point compared with its last episode.

Fox's 1.3 rating among adults 18-49 led a tightly bunched pack in primetime. CBS finished second at 1.2, followed by NBC, 1.1, and ABC, 1.0. The CW earned a 0.4.
