Variety reports that last week's premiere of NBC's new reality series 'Dog Eat Dog' placed 13th overall in Nielsen Media Research's ratings for the week ended June 23th.

FOX's 'American Idol' and 'Dog Eat Dog' led the race for the key demographic of adults aged 18 to 49, the viewer group most prized by advertisers.

The Tuesday and Wednesday editions of "American Idol," a nationwide pop music talent search show with an edge, ranked Nos. 1 and 2 in the 18-49 demographic, with "Dog Eat Dog" and the CBS crime drama "CSI" tied for third.
