Here are the weekly TV ratings, by number of viewers.

No shock that American Idol grabs the first three slots again this week (and helps push both New Amsterdam episodes into the top 20), but I'm curious as to why the Thursday results show isn't higher than the Tuesday and Wednesday episodes, and why some weeks the Tuesday ep is number 1 in the ratings and other weeks the Wednesday show is number 1.

Lost continues to impress on its new night, and if you're wondering how 20/20 got to be number 5 for the week, it was the special "Royal Family" episode.
