Ratings: Who Do You Think You Are? Hits High, Grimm Surges, Gifted Man Finale Up

NBC is singing a happy tune this morning, as a Reba McEntire-centric edition of Who Do You Think You Are? soared 50 percent week-to-week to deliver the family tree-climbing series’ largest audience ever, with 7.6 million total viewers. And the show’s 1.5 demo rating marks its best tally there since March 2010.

Leading out of WDYTYA — and with both Fringe and Supernatural out of the mix this week — Grimm (5.6 mil/1.7) saw gains of 17 and 13 percent, tying Primetime: What Would You Do? for the 9 o’clock demo win.


* Undercover Boss led the 8 o’clock hour with 9.5 mil and a 2.0, up 9 percent and a tenth. That teed up up the Gifted Man finale (9.7 mil/1.5) for gains of 8 and 15 percent. Blue Bloods was flat at 11.4 mil/1.7, but led the night in total viewers.

* Shark Tank (6.1 mil/1.7) added a few viewers but dipped a tenth in the demo.
