Roughly a third of last week’s audience for “The Moment of Truth” didn’t follow the new Fox reality show to its new, earlier timeslot last night, but even a diminished “Truth” had no trouble winning its timeslot and remaining the night’s No. 2 show behind its former lead-in and new lead-out, “American Idol.”

“Truth” averaged a 4.1 adults 18-49 rating at 8 p.m., according to Nielsen overnights, off 33 percent from last week’s 6.1 average at 9 p.m. behind “Idol.”

But “Truth” still easily won its timeslot, finishing 64 percent ahead of No. 2 “Deal or No Deal’s” 2.5 on NBC. The lie detector show also pulled a solid 10.4 million total viewers, bettering “Deal” by 194,000 viewers to win the timeslot.

“Truth,” the season’s top-rated new show, may have proven it can stand alone, which is always a concern for shows that are launched behind “Idol,” the No. 1 show on broadcast. “Truth” also averaged a decent 3.6 rating on a Monday night two weeks ago, where it aired in a one-time shot with “Idol” expanding to 90 minutes.

Fox led the night among viewers 18-49 with a 7.1 average overnight rating and a 19 share. NBC was a distant second at 2.6/7, ABC third at 2.1/6, CBS and Univision tied for fourth at 1.8/5, and CW sixth at 1.3/4.
 
Fox led each of its two hours last night, beginning with a 4.1 rating at 8 p.m. for “Truth,” followed by NBC with a 2.5 for “Deal.” ABC was third with a 2.4 for “Wife Swap,” Univision fourth with a 2.0 for “Al Diablo con los Guapos” and CBS and CW tied for fifth at 1.8, CBS for “Big Brother” and CW for “America’s Next Top Model.”
 
At 9 p.m. Fox was first with a 10.1 for “American Idol,” while ABC moved up to second with a 2.3 for “Supernanny.” NBC was third with a 1.9 for “Law & Order: Criminal Intent,” CBS fourth with a 1.8 for a repeat of “Criminal Minds,” Univision fifth with a 1.6 for “Pasion” and CW sixth with a 0.8 for a repeat of ‘The Pussycat Dolls Present: Girlicious.”
 
With Fox out at 10 p.m. NBC led with a 3.3 for “Law & Order,” with CBS second with a 1.9 for a “CSI: NY” rerun. ABC and Univision tied for third that hour at 1.7, ABC for “Men in Trees” and Univision for “Don Francisco Presenta.”
 
Fox also finished first for the night among households with an 11.2 average overnight rating and an 18 share. NBC was second at 6.6/11, CBS third at 4.4/7, ABC fourth at 4.1/7, Univision fifth at 2.1/3 and CW sixth at 1.9/3.
