LOST had 9.82 million viewers this week, down from last week's 11.27 million. But last week it wasn't up against AI in the 9 PM timeslot.
American Idol dominated the 9pm hour, though it was a more competitive hour against new episodes of Lost and Criminal Minds (and Life). Lost which had risen nicely in the demos last week (to a 5.1 among 18-49s) dropped back down to the two weeks ago level when it drew a 4.4. But last week it wasn’t up against American Idol and two weeks ago it was. So it looks pretty consistent. Lost was remarkably consistent numerically for both half hours.
