* From 10:01-11 p.m. ET, the season finale of "Grimm" (1.7/5 in 18-49, 5.2 million in total viewers) maintained its 18-49 rating of a week ago despite last night's special competition from the second hour of the "Dancing With the Stars" finale. In the time period, "Grimm" is #2 in adults 18-49, adults 18-34, adults 25-54 and virtually all other key demographics among ABC, CBS and NBC. "Grimm" is currently retaining 97 percent of last week's result in total viewers (5.220 million vs. 5.358 million), pending updates.

ABC's second place "Body of Proof" grew by 29 percent (from a 1.40 to a 1.81) and CBS's "Golden Boy" increased by 18 percent (from a 1.19 to a 1.40), meaning "Grimm's" margin of victory in the slot over #2 "Body of Proof" grew from 23 percent in L+SD (1.72 vs. 1.40) to 52 percent in L+3 (2.75 vs. 1.81).
