Only NBC and ABC were new on Friday night. At 8pm, the series finale of the cancelled Who Do You Think You Are? was up six tenths in viewers and a tenth in the demo. At 9pm, Grimm's season finale was up six tenths in viewers and a strong four tenths in the demo as it really benefits from less competition. At 10pm, Dateline NBC was down a tenth in viewers and in the demo. Over on ABC, the season finale of Shark Tank was down a tenth in viewers and the demo. ABC made the right move by making this a full season next year because it does well for a Friday and repeats well. At 9pm, Primetime: What Would You Do? was down four tenths in viewers and the demo while 20/20 was down two tenths in viewers and the demo at 10pm.
