The season finale of So You Think You Can Dance (2.1/7, 6.3 million) was up 24% in 18-49 and 17% in total viewers from last week but down 13% in the demo from last summer’s finale. In the preliminaries, Fox (2.1/7) is running behind CBS (2.3/7) for the night in 18-49, but CBS’, ABC’s and NBC’s numbers were inflated by local NFL preseason preemptions, and Fox is projecting that it will win Thursday in the demo when the finals are released this afternoon. Without adjustments, CBS’ Big Brother (3.2/9) grew 13% from last week and was the night’s the highest-rated program by a mile. ABC’s Wipeout (1.9/6), Expedition Impossible (1.6/4) and Rookie Blue (1.4/4) were all on par. NBC ran all repeats.
