There wasn’t much movement in Wednesday’s ratings race, with NBC’s “America’s Got Talent” again edging out Fox’s “MasterChef” and CBS’ “Big Brother” in demos while comfortably ruling as the night’s most-watched program overall.

According to preliminary national estimates from Nielsen, NBC followed its 8 p.m. “America’s Got Talent” repeat (1.5/5 in 18-49, 6.6 million viewers overall) with the live results show at 9 p.m. (2.3/7 in 18-49, 10.0 million viewers overall), which was just about in line with last week and was up vs. the comparable night a year ago. Closing out the night for NBC was scripted drama “Camp” (1.2/4 in 18-49, 4.2 million viewers overall), which is up either one or two tenths week to week depending on how the nationals come in.

NBC won the night in 18-49, 25-54 and total viewers.

Elsewhere, Fox’s “MasterChef” (2.2/7 in 18-49, 5.4 million viewers overall) was down slightly from last week to place a close second to “Talent” in 18-49 while beating it in adults 18-34 (2.0 to 1.7). The net opened the night with a repeat of last week’s “MasterChef” (1.0/4 in 18-49, 2.6 million viewers overall).

CBS’ “Big Brother” (2.0/7 in 18-49, 6.1 million viewers overall) seems to have cooled a bit, down three tenths from last week but again winning its hour opposite all repeats on the other major nets. It was followed by repeats of “Criminal Minds” (1.0/3 in 18-49, 4.8 million viewers overall) and “CSI” (1.2/3 in 18-49, 6.2 million viewers overall), the latter of which led its hour in 18-49 (either tied or outright over “Camp,” depending on the nationals), 25-54 and total viewers.

At ABC, “The Lookout” (0.9/3 in 18-49, 3.5 million viewers overall) held steady in 18-49 while hitting a five-week high in total viewers. Earlier in the evening, the net aired encores of comedies “The Middle” (0.8/3 in 18-49, 3.6 million viewers overall), “Suburgatory” (0.7/2 in 18-49, 2.9 million viewers overall), “Modern Family” (0.9/3 in 18-49, 3.3 million viewers overall) and “The Neighbors” (0.6/2 in 18-49, 2.3 million viewers overall).
