"Nightline" also squeaked by Conan in A25-54 viewers with 1,473,000, to "The Tonight Show's" 1,466,000. Last week saw the lowest Total Viewer and A25-54 averages for "The Tonight Show" since the 1991/92 season.

"Nightline" was up 21% versus the same week last year and is up 14% among Total Viewers and up 3% among A25-54 viewers, season-to-date.
