Buoyed by the return of late John Ritter's sitcom 8 Simple Rules for Dating My Teenage Daughter (17 million viewers), ABC won the first Tuesday of the new season among adults 18-49. Rules also gave a boost to the premiere of new comedy I'm with Her, which attracted 13.1 million viewers. Elsewhere, CBS's JAG spinoff Navy NCIS averaged a respectable 12.4 million viewers, and NBC's relocated Law & Order: SVU easily beat ABC's NYPD Blue and CBS's Judging Amy at 10 pm. The WB's new teen drama One Tree Hill, meanwhile, fouled out with a lousy 2.8 million viewers.
