Demo a no-show for 'Late Show'


CBS' "Late Show With David Letterman" tied its lowest-ever adults 18-49 rating last week.

"Late Show" averaged a 0.9 rating in adults 18-49, Nielsen Media Research said. That is its lowest ever for an original since the program premiered in 1993, though not the lowest for the show: It has hit 0.9 several times, most recently in late December when it was in reruns because of the WGA strike.

Meanwhile, "The Tonight Show With Jay Leno" averaged a 1.3 rating in the demo, its biggest margin of victory against "Late Show" in four months. "Late Show" tied for second place in the demo rating with ABC's "Nightline," though "Nightline" had more viewers in the demo. Both "Tonight" and "Late Show" showed drops in viewers and the demo.

Friday's "Nightline" wasn't included in the ratings. (partialdiff)
