American Idol continued to steamroll the competition Tuesday night, attracting nearly 30 million viewers and hitting a new high among young adults. Even more impressive, Idol outdrew ABC, CBS and NBC combined at 8 pm. UPN also had cause to celebrate as the latest episode of America's Next Top Model pulled in more than 7 million viewers and ranked as the network's third-highest-rated telecast ever among bitchy anorexic women 18-34.
