I don't think they want. No one knows at this point how these electronic publishers will perform. Gernert says that electronic publishers have approached Grisham, but none has succeeded in persuading him to go digital, partly because the needs of author and e-publisher don't, as Gernert sees it, entirely coincide. As an author you would want a story to go on as many computers, Web sites and devices as possible. They'd prefer to leave the business of promoting a book and getting it to readers to a publisher.
Publishers are printers and foot the marketing bill.
The other problem for authors is distribution. Publishers know how to distribute books. As many have observed, if King wanted to get into the business, he could certainly afford to buy his own publishing house. I think we will be having a very different and interesting conversation about this issue in three years. I think a lot is going to change.
