( CNN ) -- But Kellie Pickler was so popular ! In the end , though , the allure of the pixie-haired hoofer was n't enough : Tuesday 's two-hour finale of `` Dancing with the Stars '' only earned a 2.6 rating/7 share in adults 18-49 , down 21 % from last year 's spring results ( 3.3/9 on May 22 , 2012 ) to become the lowest-rated finale in the franchise 's history , according to Nielsen . Since the show averaged 14.9 million viewers , ABC came in first for the night in eyeballs but second in the demo behind NBC , which was buoyed by `` The Voice . '' Speaking of which : NBC 's singing competition , which earned a 3.1/9 , was down 11 percent versus last week but it still ruled at 9 ( where it averaged 9.9 million ) . It was preceded by a special about Oklahoma ( 2.0/6 , 8.1 million ) and followed by the Grimm finale ( 1.7/5 , up 6 % from last year , 5.2 million ) . Fox came in third with a two-hour installment of `` So You Think You Can Dance '' ( 1.9/6 , 4.5 million ) while CBS trailed in fourth with a bunch of pesky `` NCIS '' repeats .
