Times change and so do tastes. What was popular with the public once is no longer popular anywhere but in literary circles. It stands to reason that it wouldn't be picked up. I've been trying to get published, and the only thing I've gotten published was a poem I wrote during the Gulf War - and I suspect that the only reason why it was published was because it was written by a high school student. Publishing companies do not always give you a rejection - rather your manuscript is sent into the literary black hole never to be seen again.
If you truly want to be published you have a couple of choices. 1) Do it yourself (just be very careful which company you go with - some of them will rape you of all your rights) or 2) get an agent. At least that's what I've been told.
