Very true, it's notable that there are noticeably fewer Star Trek and Star Wars novels on the shelves of your average Waterstone's now than there were about 15 years ago, when both (especially Trek) were going through something of a relative doldrums in popularity compared to now. It's not as if spinoff novels aren't still being written, they just seem to be noticeably less present there than on the Kindle store and so on.I wonder how much of that is due to the sheer glut of literary science fiction of all forms that made up the contents of bookshelves at the turn of the century. As we've discussed previously it represented a high watermark for spin-offs of the likes of Doctor Who, Star Trek, Star Wars but even beyond those recognisable properties think the science fiction paperback was seeing a boom of every type and aimed at all ages. Maybe that rising tide lifted the AH titles along with it.
