Ratings: ‘The Voice’ Slips, But Still Tops; ‘NCIS’ Franchise Continues to Slide (Update)

NBC's singing competition continues to reign despite hitting a lower note among adults 18-49

(Editor's note: Includes updated Wednesday afternoon numbers from NBC.)

NBC's hit singing competition "The Voice" managed to retain its ratings dominance despite a pronounced dip in the ratings, while CBS's "NCIS" and "NCIS: Los Angeles" continued to slip after hitting low points last week .

According to preliminary numbers, "The Voice" once again scored top ratings in the adults 18-49 demographic Tuesday at 10 p.m. despite a 16 percent drop from last week (when it aired from 9 to 11). Christina Aguilera and the rest of the gang took a 4.7 rating/12 share in the demo, nabbing 10.5 million total viewers. NBC's evening began with a two-hour episode of "The Biggest Loser" at 8, which was also down, albeit a relatively modest 4 percent, with a 2.6/7 in the demo and 6.8 million total viewers.

Dramatic gains followed for the network, with "Raising Hope" at 9 jumping 22 percent versus last week with a 2.2/6 in the demo and 5.4 million total viewers, and "Traffic Light" earning a 27 percent spike in the demo with a 1.4/4 and 3.2 million total viewers.

ABC's formerly reliable ratings winner "Dancing With the Stars" was up 7 percent compared to the previous week with its 9 p.m. results show, but found itself in 4th place ratings-wise for the evening. "DWTS," which featured a performance by Michael Bolton, nabbed a 3.2/8 in the demo and 17.1 million total viewers. "Body of Proof" the following hour was also up, with a 3 percent improvement over last week, taking a 2.1/6 in the demo and 10.3 million total viewers. "Dancing With the Stars: The Encore" kicked off the evening for ABC at 8 with a 2.0/6 in the demo and 11 million total viewers.

CBS took a couple of hits Tuesday night, with its "NCIS" franchise hitting season lows. "NCIS" at 8 was down five percent from the previous week, taking a 3.5/11 in the demo and 17 million total viewers. Meanwhile, "NCIS: Los Angeles" also reached a season nadir, dipping 3 percent to receive a 2.8/8 in the demo and 14.7 million total viewers. The evening's closer, "The Good Wife," was also down, experiencing a 17 percent decline versus last week, with a 2.0/5 in the demo and 11.5 million total viewers.
