(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.
