While ratings for CBS's The Late Show With David Letterman are down 11 percent and NBC's The Tonight Show with Jay Leno are down 5 percent in 2006, those for ABC's Nightline are up 2 percent for the year and up 15 percent in last week's showings, the Philadelphia Inquirer observed today (Monday). In an interview with Inquirer TV columnist Gail Shister (who has branded the show "Nightline Lite -- less filling, more popular"), James Goldston, the former BBC producer who took over as executive producer of Nightline last November, said, "It's early. I'm pleased that we're up, but it's not enough. We have a long way to go before I'm satisfied with what we're doing."
