'Survivor,' 'Mentalist' play well in 18-49 demo

Airing first-run episodes of its Thursday shows against competition made up mostly of repeats, CBS had no trouble winning the night’s ratings race among viewers 18-49 and overall, according to preliminary nationals from Nielsen.

CBS has been No. 1 in 11 of the past 12 primetime hours in the demo, losing narrowly to the first hour of Fox’s “So You Think You Can Dance” season finale Wednesday.

The Eye kicked off the evening with “Survivor: Samoa” (3.9 rating/12 share in 18-49, 12.4 million overall), followed by “CSI” (3.5/10, 15.5 million) and “The Mentalist” (3.5/10, 15.7 million).

NBC rested its Thursday sitcoms in favor of clip special “Saturday Night Live Presents ‘A Very Gilly Christmas’” (3.1/9, 7.8 million), which finished second to CBS throughout its two-hour airing. The Peacock wrapped up its night with “The Jay Leno Show” (1.7/5, 5.2 million), which outperformed ABC’s repeat airing of “Private Practice” (1.0/3, 3.1 million).

ABC struggled earlier in the evening with repeats of “Grey’s Anatomy” at 8 p.m. (0.9/3, 3.9 million) and 9 p.m. (1.2/3, 4.1 million). The 8 p.m. airing barely staved off “The Vampire Diaries” (0.8/3, 1.8 million) on the CW, which has devoted its week to repeats of its top new show. (“Vampire” drew a 0.8/2, 1.9 million at 9 p.m.)

Fox was also sluggish Thursday among viewers 18-49 with reruns of “Bones” (1.8/6, 6.9 million) and “Fringe” (1.2/3, 3.9 million).

Preliminary 18-49 averages for the night: CBS 3.6/10, NBC 2.6/8, Fox 1.5/4, Univision 1.3/3, ABC 1.0/3, CW 0.8/2.

In total viewers: CBS 14.6 million, NBC 6.9 million, Fox 5.4 million, ABC 3.6 million, Univision 3.5 million, CW 1.9 million.
