With no NFL game on Thursday — and only a couple of originals on the other broadcast networks — a mostly new CBS lineup scored an easy ratings win in primetime.

“Young Sheldon” led the night in both total viewers (11.2 million) and adults 18-49 (1.7 rating). The latter was a season low for the show and the first time it’s gone below 2.0. It was also the first time it aired without a new “Big Bang Theory” as a lead-in.

“Mom” (1.4) and “Life in Pieces” (1.1) were both even with last week, and “SWAT” improved a tenth of a point to 1.1.

The only other new shows on the night were a pair of “Great News” episodes on NBC. They managed only 0.5 and 0.4. “A Saturday Night Live Christmas” drew a 1.1.

Network averages:

Adults 18-49 rating/share 1.3/6 0.9/4 0.9/4 0.3/1 0.2/1
Total Viewers (millions) 8.14 4.73 3.30 1.29 0.71

Rating: Estimated percentage of the universe of TV households (or other specified group) tuned to a program in the average minute. Ratings are expressed as a percent.
Fast Affiliate Ratings: These first national ratings are available at approximately 11 a.m. ET the day after telecast. The figures may include stations that did not air the entire network feed, as well as local news breaks or cutaways for local coverage or other programming. Fast Affiliate ratings are not as useful for live programs and are likely to differ significantly from the final results, because the data reflect normal broadcast feed patterns. 
Share (of Audience): 
The percent of households (or persons) using television who are tuned to a specific program, station or network in a specific area at a specific time. 
Time Shifted Viewing:
 Program ratings for national sources are produced in three streams of data – Live, Live +Same-Day and Live +7 Day. Time-shifted figures account for incremental viewing that takes place with DVRs. Live+SD includes viewing during the same broadcast day as the original telecast, with a cut-off of 3 a.m. local time when meters transmit daily viewing to Nielsen for processing. Live +7 ratings include  viewing that takes place during the 7 days following a telecast.
