Nightline’s Highest Viewership Since Relaunch

For the fifth straight week, ABC’s Nightline beat CBS’ Late Show with David Letterman in both Total Viewers and the A25-54 demo.

Last week it was a bigger milestone for Nightline — the program saw its highest total viewership since the relaunch in November 2005.

Both networks grew week-to-week in both categories. The Tonight Show with Jay Leno was #1 in Total Viewers and the demo.
