Fox’s “American Idol” was again the top-rated show Wednesday night in every major ratings demographic, but UPN’s “America’s Next Top Model” made a strong start in its sixth outing.

“Idol” was No. 1 for the night in adults 18 to 49 with a 12.3 preliminary national rating, a number that includes live-plus-same-day viewing, according to Nielsen Media Research. It outpaced its closest competition in the demo, its lead-out “Bones” (4.8), by 162 percent.

“Top Model” scored a 2.5 in the demo for its two-hour premiere, outperforming its fall 2005 fifth installment premiere (2.3) by 9 percent and its fourth installment premiere last spring (2.2) by 14 percent. In the women 18 to 34 demo, “Top Model” hit a 4.7 rating, second only to “Idol” for the night in that demo.

Fox was the top network for the night in adults 18 to 49 with an 8.5, followed by CBS (3.7), ABC (2.6), NBC and UPN (both 2.5) and The WB (0.9).
