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.
