CBS continued its Thursday ratings dominance, with all four of its prime-time programs winning their time slots, according to live-
plus same-day ratings released Friday by The Nielsen Co.
CBS averaged 12.75 million viewers to finish first on Thursday for the seventh time in the eight weeks of the prime-time television season.
The night's most-watched program was the CBS crime drama, ``The Mentalist,'' which averaged 13.84 million viewers.
ABC was second for the night, averaging 7.78 million viewers. Its most-watched show was ``Grey's Anatomy,'' which averaged 11.13 million, putting it fourth for the night behind CBS' ``The Mentalist,'' ``The Big Bang Theory'' and ``CSI: Crime Scene Investigation.''
CBS also led among viewers ages 18-49, the group advertisers pay more for because they watch less television and are harder to reach, and viewers ages 25-54.
ABC was first for the eighth consecutive Thursday among women ages 18-34 and 18-49.
