Slate wonders if novelizations are endangered species:
novelizations have been supplanted by big-selling tie-ins—original novels based on existing properties such as Buffy the Vampire Slayer, CSI, or Halo—and the Internet. In a DVD world, the idea of using a book to relive the pleasures of a film is practically counterintuitive.
[…]The home-theater revolution may have wiped out a large part of the novelization market, but the lessons learned may wind up sustaining the genre. When DVDs first arrived, the studios quickly realized that they could get fans to "double dip" by issuing a bare-bones release of a movie and then following it with a "Deluxe Edition" loaded with special features. Now it looks like literary special features—expanded back stories, cut scenes, and deleted characters—might just make the novelization relevant again.
