ABC led the Thursday primetime ratings this week, with “A Charlie Brown Christmas” scoring a 1.2 rating in adults 18-49 at 8 p.m., making it the night’s highest-rated broadcast. It was followed by the 2-hour finale of “The Great American Baking Show,” which ticked up a tenth from its 0.6 last Thursday to a 0.7 this week.

On CBS, the season finale of “Murphy Brown” scored a 0.7 as well, matching its previous episode and tying its season low. It was the network’s only original broadcast of the night. “The 4th Annual Howie Mandel Stand-up Extravaganza” filled out the night for the CW with a 0.2 average and 1.05 million viewers.

Elsewhere, NBC’s previously-announced, 2-hour “Timeless” series finale raked in a 0.6 average on the network. This puts it even with its season 2 average in the demo, but with an audience of 3.22 million viewers, it is also the show’s most-watched broadcast since its first season finale in February, 2017.

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.
