TV Ratings: 'X Factor' Premiere Shrinks 25 Percent Against 'The Voice'

The Fox series returns for its sophomore season and wins the night for the network, but it loses in the demo and total viewers going head-to-head at 8 p.m. and falls from its 2011 debut.

One night may not be big enough for two singing competitions.

With NBC adding an episode of The Voice to this Wednesday, up against the sophomore season premiere Fox's The X Factor, both series saw double-digit drops from their most recent outings.

The X Factor's two-hour premiere averaged a 3.3 rating among adults 18-49 last night, according to fast affiliate ratings. That's a 25 percent drop from last year's series premiere, though a smaller drop from the December finale (3.8 adults rating.) In total viewers, X Factor averaged 8.5 million viewers.

Head-to-head competition with the 8 p.m. hour of X Factor gave The Voice a victory. Though the 3.3 adults rating matches Factor's total haul, the Fox show only pulled a 2.7 adults rating in direct competition with The Voice. (In its second hour, X Factor grew 40 percent.) In total viewers, The Voice pulled in 10.7 million.

America's Got Talent, entering its home stretch, pulled a 2.9 rating among adults 18-49 before a preview episode of Guys With Kids (2.2 adults rating) and an encore of The New Normal (1.4 adults rating). For the night, NBC pulled in a 2.7 rating with 18-49-ers and a dominant 8.9 million viewers.

Big Brother was down just a tenth of a point from last Wednesday on CBS, pulling a 2.0 adults rating and giving the network an average of 1.5 in the demo with encores. CBS averaged 6.1 million viewers.

Encores gave ABC a 0.9 rating among adults 18-49 and an average 3 million viewers.

The CW had a new episode of Oh Sit pull a steady 0.4 adults rating, leaving it seemingly unaffected by the increased reality competiton.
