No major moves on Friday, though ABC continues to strengthen its lineup and is challenging CBS for the top position in the demo on the night. After successfully introducing Primetime: What Would You do? in the 9 PM hour once earmarked for new drama procedural Body of Proof, ABC last night added Supernanny at 8 PM where it had been airing repeats of its new series for additional sampling. In its season premiere, the veteran reality series (1.2/4, 4.8 million) was up by 9% in 18-49 and by 7% in total viewers from its opener last fall. With Primetime (1.7/6) and 20/20 (1.6/5) flat with last week, ABC finished the night with an average of 1.7 in 18-49, two tenths behind leader CBS.

At CBS, Medium (1.5/5, 6.9 million) was up by a tenth from last week. CSI: NY (2.0/6, 10.4 million) was up by 11% and ranked as the top program of the night in 18-49 and total viewers, while Blue Bloods (1.7/6, 10.2 million) hit a low.

Fox’s lineup was up: House repeat (1.0/4) was up 25%, The Good Guys (0.8/3) was up a tenth, or 14%. NBC was status quo: School Pride (0.6/2, 2.3 million), once again the lowest program of the night in 18-49 and total viewers), and Dateline (1.3/5), both even with last week’s deliveries.

At the CW, Smallville (1.1/4, 2.6 million) was down a bit while Supernatural (1.1/4, 2.4 million) was on par.
