NEW YORK – Jay Leno and David Letterman are in the twilight of their days as late-night TV kings, and it’s not clear that any late-night comic will wield that kind of broad influence again.
Late-night ratings sank over the past three months, despite the attention and extraordinary television created over the winter by the drama of Leno taking back “The Tonight Show” from Conan O’Brien.
“Late-night talk shows have been around since the 1950s, and you wonder if they are getting passe with the viewing public,” said Brad Adgate, an analyst with Horizon Media.
