Tuesday night's ratings for American Idol once again outpaced the ratings for all of its competition together. The show scored a 15.9 rating and a 24 share for Fox. The huge total also helped get Fox's new sci-fi cop drama New Amsterdam off to a solid, if unspectacular, start with an 8.3/12. It came in well ahead of second-place The Biggest Loser on NBC, which recorded a 6.5/10.
