CSI-fueled CBS killed the competition during the third week of the new TV season, ranking No. 1 among total viewers and adults 18-49. Comeback kid ABC, meanwhile, squeaked past NBC for second place, thanks in large part to breakout hits Desperate Housewives and Lost. Speaking of the Peacock, the once-dominant network had just one show in the top 10: ER. The top five shows of the week were as follows: CSI, Without a Trace, CSI: Miami, Desperate Housewives and Survivor: Vanuatu.
