In its second outing last night, ABC's castaway thriller Lost attracted 16.3 million viewers — down just 15 percent from its blockbuster debut. The Tuesday premiere of Wife Swap also looked solid with 11.1 million viewers, while UPN's Kevin Hill got off to a decent start (by UPN standards) with more than 4 million viewers. CBS, meanwhile, took the night thanks to another strong installment of CSI: NY, which once again trounced Law & Order.
