It was a night of mostly encores in the Thursday night primetime ratings this week, with almost all of the broadcast networks choosing to air reruns of shows that’ll be making their returns next week.

CBS’ “Big Brother” was the only original program and led the night in the adults 18-49 demo with a 1.6 rating – even with its Thursday night broadcast from a week ago – with 6.19 million viewers. Whether or not “Big Brother” will be able to maintain those numbers later today, when a local “Thursday Night Football” pre-emption in Cleveland is factored out, will have to wait to be seen.

In late-night, NBC’s “The Tonight Show” won the no. 1 spot with a 0.5, followed by “The Late Show” (0.4) and “Jimmy Kimmel Live!” (0.4). “Late Night with Seth Meyers” (0.3) and “Nightline” (0.3), meanwhile, tied for the top spot of the 12:35 a.m. hour.

Network averages:

Adults 18-49 rating/share 1.2/5 0.7/3 0.4/2 0.4/2 0.2/1
Total Viewers (millions) 6.12 3.14 2.36 1.50 0.64


Late-night metered market ratings (adults 18-49, households):

11:35 p.m.

“The Tonight Show Starring Jimmy Fallon”: 0.5/3, 1.7/5

“The Late Show with Stephen Colbert”: 0.4/3, 2.5/7

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.
