The season seven finale of Fox’s So You Think You Can Dance was the top performer on Thursday, winning the night among adults and teens. The competition show earned a 2.4 rating/8 share in adults 18-49 and averaged 7.2 million viewers, up 33% in the demographic and up 29 percent in viewers versus last Thursday. The Dance finale was down 8%, however, in the demo versus last season’s finale on Dec. 16, 2009.

Still, Fox reports that this summer’ cycle of Dance outperformed its fall ’09 average by 8% in total viewers.

Meanwhile, last night’s live eviction show of Big Brother won its time period in viewers and key demographics and out-delivered both last week and last year’s comparable broadcast. BB won its timeslot in viewers (7.93 million) and adults 18-49 (2.6/9) and added an additional 790,000 viewers versus last week.

Compared to the same night last year, Big Brother was up 4% in adults 18-49, 17% in adults 18-34 and added 1 million viewers (from 6.93 million).

Overall, Fox won the night in the key adult demographic but CBS attracted the most viewers with 7.8 million.
