Fast National ratings for Wednesday, April 30, 2014.

Even with "Chicago PD" topping CBS' backdoor "CSI" pilot among young viewers, CBS was still able to ride "Survivor" and "Criminal Minds" victory both overall and in the key demographic on Wednesday night.

[NBC had an NBA preemption in Portland, which will probably make the 10 p.m. race closer.]

With CBS' full lineup returning for originals (and perhaps with NHL and NBA playoff competition on cable), there were big drops for ABC's "Modern Family"  (a whopping 0.6 key demo rating from last week's Fast Nationals), "Suburgatory" and "Nashville," as well as FOX's "American Idol" and NBC's "Law & Order: Special Victims Unit."

Over on The CW, "Arrow" was up a hair, while "The 100" continued to hold onto its lead-in well, making its case for renewal.

On to the numbers...

Among adults 18-49, CBS averaged a 2.1 rating for Wednesday night, beating FOX's 1.8 rating in the key demographic. NBC's 1.7 key demo rating and the 1.6 key demo rating for ABC followed closely, while The CW averaged a 0.7 key demo rating for the night.
