Some local NBC affiliates have become so concerned about the dreadful ratings of the new Jay Leno Show that they may bump the show and insert "alternatives" of their own choosing in the 10 00 p.m. hour, the Los Angeles Times reported today (Monday). The newspaper observed that Leno's poor lead-in has resulted in some local stations' newscasts at 11 00 p.m. taking a dive in the ratings. Craig Allison, who runs KSHB in Kansas City, told the Times "I'm not pleased with what Leno is doing. I don't think anybody is." In Boston, WHDH's ratings for its 11 00 p.m. newscast have fallen 17 percent from a year ago. But Jordan Wertlieb, who manages WBAL in Baltimore, where his longtime dominant newscast has Fallen To second place, has urged patience. "People want to declare the game over because we are down a couple of runs after the first inning. There is a long way to go," he said.
