I thought of asking this question on CT last night, and kicked myself for not thinking of it sooner., because there are supposedly a lot of media types and workers on here. Now with Letterman retiring, I might as well ask.

I know late night talk shows are part of the studio's PR business and the actors are booked to plug a movie or whatever. But do the hosts have any say in who they book, and can they override the machine? Are the conventions of talk shows that they've always had celebrities on—that's the nature of the genre? Because I would rather see more authors, like Colbert and Stewart have—and the audience, if it is a fan of the comedy and the personalities of the hosts, will follow along. Ferguson has a show unlike any other, but he still has too many actors on. Occasionally he can do a long interview without doing comedy, as he did with Stephen Fry, but why would he not do that anymore? What is up with the preinterviews on certain topics for the others? People watch any TV show because they like the characters. If they reguarly watch late night, they like the host. If the host did new and original things, that would be interesting, like a new plot in a series. It would break up the stodgy way these programs have been done for years. To an audience, it would be a breath of fresh air.
