UPDATED with final numbers: CBS’ Big Brother remained Thursday’s top-rated and most-watched show in primetime, but all of the night’s programming dropped in the final Nielsen numbers after pre-emptions for a full night of preseason NFL football were taken into account.

Big Brother finished with a 1.3 rating in the adults 18-49 demo, down from an early 1.8, but still the only show to crack a 1.0 on a night of mostly repeats. ABC had the only originals: the season finale of ABC’s The Gong Show (0.4, adjusted down from 0.8) at 8 PM and back-to-back episodes of Take Two at 9 PM (0.2, down from 0.9) and 10 (0.4, from 0.8).

The reruns on CBS (0.7, 3.30 million viewers) gave the network an overall victory in both key metrics.

PREVIOUSLY, 10:15 AM: CBS’ Big Brother (1.8 rating in the 18-49 demo, 6.86 million viewers) easily topped Thursday’s broadcast ratings, which were skewed by the last full slate of NFL preseason games which infiltrated network affiliates’ primetime schedules. Expect these early numbers to be adjusted down quite a bit in the finals; we’ll update when those numbers come in.

Still, for now 9 PM’s Big Brother was the night’s top-rated and most-watched show as one of Thursday’s only originals.

ABC was the only other network to offer fresh fare, with the season finale of The Gong Show (0.8, 4.22M) at 8 PM followed by back-to-back episodes of Take Two at 9 (0.9, 4.50M) and 10 (0.8, 3.65M). Gong Show was up three-tenths from last week’s preliminary rating, reflecting the NFL’s impact.

NBC and Fox showed all repeats, as did CBS outside its reality staple.

Overall early numbers, per Nielsen: CBS (1.3, 5.89M), Fox (1.2, 4.18M), NBC (0.9, 4.10M), ABC (0.8, 4.13M), the CW (0.4, 1.30M).
