Thursday's Idol wound up in third place with 16.71 million, barely edging out NCIS Los Angeles with 16.15 million viewers. NBC held on to a spot in the top ten with The Voice, which through a ratings anomaly, wound up in fifth place although with slightly more viewers -- 16.28 million -- than the fourth-place finisher. Among the evening newscasts, NBC Nightly News with Brian Williams , with 9.50 million viewers, widened its lead over ABC World News with Diane Sawyer , with 7.97 million viewers.
