Ellen DeGeneres' debut behind American Idol's judging table lifted the Fox hit's numbers as it remained Tuesday's most-watched program.
Idol's first night of Hollywood Week drew 27.7 million viewers, climbing 12 percent in the adults-18-to-49 demographic from the previous week and 4 percent in total viewers from Season 8's first night of Hollywood Week. Placing second at 8/7c was NCIS (19.7 million viewers), which took a small dip. NBC's Biggest Loser struggled against the tough competition in the first hour, but improved greatly in its second, averaging 9.5 million viewers overall.
