NBC backs Jay Leno despite slump in ratings

US chat-show host Jay Leno's revamped primetime show is failing to draw viewers, leaving his future up in the air, according to reports.

Leno moved to NBC's primetime slot six weeks ago, but after a strong start viewing figures for his 10pm show have fallen sharply.

The show is reportedly pulling in 25 per cent fewer audience members than its preceding shows a year ago.

But an NBC spokesman said, "We believe in the combination of a bankable star like Jay Leno hosting an exciting, topical show five nights a week and are committed to continuing to engage with our affiliates in ways to make that relationship work."

Most of NBC's affiliates are said to back a long-term strategy for the show to play out over 52 weeks.

"Some of the significant dramas right now are going to run out of steam by December and be out until February,” said DJ Wilson, general manager at KGW in Portland, Oregon.

“There is a real opportunity for Leno to pop. We really agree that this is a marathon, not a sprint."

However, one manager, who wanted to remain anonymous, said that he is giving Leno until next year to improve ratings.

He said: "I give them through February. I don't think anybody is anxious to pull any triggers. Plan B is to give the 10pm hour back to the affiliates."
