Reality show nabs 7.4 million viewers Thursday

“So You Think You Can Dance” was judged the winner by Thursday primetime viewers ages 18-49, according to Nielsen preliminary nationals, enabling Fox to score a victory in the demo. CBS topped the night in overall viewers.

“Dance” (2.5 rating/8 share in 18-49, 7.4 million viewers overall) appeared to decline slightly from its previous-week numbers but still came in above CBS’ “Big Brother 11″ (2.0/7, 6.4 million).

CBS nonetheless had the most-watched program of the night overall in “The Mentalist” (1.8/6, 8.3 million), which aired after “CSI” (1.4/4, 7.5 million).

NBC’s comedy block from 8-10 p.m. — “30 Rock” (1.1/4, 3.8 million, “Parks and Recreation” (1.0/3, 3.0 million), “The Office” (1.3/4, 3.2 million) and another “30 Rock” (1.3/4, 3.0 million) — had middling summertime results, though its perhaps worth noting that “Parks” held onto 91 percent of its “30” lead-in. “Law and Order” (1.2/4, 4.2 million) wrapped up the Peacock’s night.

Two reruns of “Grey’s Anatomy” (0.8/3, 3.4 million and 1.0/3, 3.3 million) didn’t help ABC, which trailed Univision in 18-49 and overall viewers Thursday. “Private Practice” (0.7/2, 2.4 million) further lowered the Alphabet’s perf.

Fox preceded “Dance” with “Bones” (1.5/5, 5.2 million), which finished second at 8 p.m. behind “Big Brother.”

“Smallville” and “Supernatural” (each 0.5/2, 1.3 million) drew relatively typical numbers for the CW.

Preliminary 18-49 averages for the night: Fox 2.0/7, CBS 1.7/6, Univision 1.4/4, NBC 1.2/4, ABC 0.8/3, CW 0.5/2.

In total viewers: CBS 7.4 million, Fox 6.3 million, NBC 3.5 million, Univision 3.4 million, ABC 3.0 million, CW 1.3 million.
