Fast National ratings for Wednesday, January 15, 2014.
 
The Season 13 premiere of "American Idol" was down by 23 percent in the key demographic and by 16 percent overall on Wednesday night, making it the lowest rated "Idol" premiere ever in the demo and the lowest season Season 1 in viewers. FOX still dominated Wednesday in all measures.
 
While the percentage drops from last winter's premiere speak for themselves, FOX still has some spin: For the first time since Season 10, "Idol" premiered with higher ratings than its finale. That's a reflection more on how low the Season 12 finale was than anything else, but still. Also, FOX notes that "Idol" tied the most recent premiere of "The Voice" in viewers.
 
Well OK!
 
Meanwhile, "Suburgatory" retained demo numbers decently from "The Middle" in its latest premiere, but dropped steeply in viewers. The second week of "Chicago PD" was also down against returns for "CSI" and "Nashville."
 
Let's get to the numbers...
 
Among adults 18-49, FOX averaged a 4.6 rating for Wednesday night, comfortably winning the key demographic. CBS was second with a 1.9 key demo rating, followed closely by the 1.8 key demo rating for ABC. NBC's 1.4 key demo rating and the 0.8 key demo rating for The CW trailed.
 
Overall, FOX averaged very nearly 15 million viewers and a 8.7 ratings/14 share for Wednesday night. CBS was second with a 5.6/9 and 8.65 million viewers, followed by ABC's 4.0/6 and 6.09 million viewers. NBC's 3.5/6 and 5.3 million viewers was still far ahead of the 1.3/2 and 2.04 million for The CW.
