Fox’s ”The X Factor” won three of its four half-hours among young adults Wednesday, lifting the net to a demo victory. ABC’s ”Modern Family” was again the night’s No. 1 series, but the entire net’s lineup returned down some after being preempted for the CMA Awards last week.

According to preliminary national estimates from Nielsen, ”The X Factor” averaged a 3.8/10 in 18-49 and 11.2 million viewers overall from 8 to 10 p.m., growing with each half-hour and on par with last week. In adults 18-34 (3.4/10), the music contest had its best showing for a regular episode since its premiere.
