TV Ratings: 'Person of Interest', 'Scandal' Hit Highs

The two dramas see the Thursday's biggest surges, while "X Factor," "30 Rock," "Grey's Anatomy" and "Big Bang Theory" all dip.

CBS scored an easy win in adults 18-to-49 (3.4 rating) and total viewers (13.9 million) on Thursday night, starting with a slightly off The Big Bang Theory. The comedy was down two tenths of a point to a 5.3 rating, before Two and a Half Men (4.2) grew by the same measure. Person of Interest pulled a season high 3.2 adults rating, up three tenths of a point, while Elementary rose one tenth to a 2.3 in the demo. The networks' Denver affiliate carried the NFL game between the Broncos and Oakland Raiders, so final ratings are subject to change.
