Final broadcast primetime live + same-day ratings for Thursday, September 20, 2018

As expected, with local NFL pre-emptions factored out, several shows adjusted down from their early adults 18-49 ratings to the finals this afternoon. CBS’ “Big Brother” (1.5) ticked down one-tenth from its initial rating, as did the network’s “Young Sheldon” (1.1) rerun.

NBC’s back-to-back “Good Place” repeats (0.4, 0.4) each adjusted down three-tenths and two-tenths from their early numbers, while the “Law & Order: SVU” encore also ticked down from a 0.8 to a 0.5. Additionally, CBS’ “SWAT” rerun slipped from a 0.7 to a 0.5.

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.
