Ratings: 'American Idol' hits another flat note, stays at series demo low

Fox's "American Idol" added some viewers this week, but the singing competition stayed at a series low in the advertiser-sought 18-49 demographic.

CBS finished first outright last night, despite lead show "Survivor" dipping 12 percent versus the prior Wednesday.

The CW's lineup rose double digits, though the network only managed a fifth-place demo tie with NBC, which ran all reruns.
