CBS dominated the late-season week, topped by ‘NCIS’ with more than 18 million viewers. The veteran drama is poised to surpass ‘Sunday Night Football’ as the season’s most-watched program in total viewers. Meanwhile, ‘The Big Bang Theory,’ which placed second for the week, is ready to take the 18-49 crown.

Among shows that beat FOX’s ‘American Idol’ in the all-important demo this week: ‘Big Bang’ and ‘Grey’s Anatomy.’ ‘Idol’ placed 9th and 10th, respectively. One interesting thing about this week’s top 10: All broadcast networks had at least one show place. For NBC it was ‘The Voice’ and ABC had ‘Dancing With the Stars.’
