David Cook wins "American Idol"

And the early overnight numbers are in: The two-hour season finale (which was surprisingly entertaining), averaged a 17.5 household rating and 27 share, down from the 19/30 the 2007 finale earned.

UPDATE: The adults 18-49 ratings are in, and Idol drew a 11.0/29, down slightly from 11.5/31 achieved for last year’s finale. On the other hand, Idol drew 30.6 million viewers, compared to 29.5 million last year.

Um, what Idol decline? The show is still a powerhouse (much as yours truly hates to admit it.)
