Hi everyone!
Just thought I'd do what I can to clear up a little confusion... hope I don't inadvertently cause more! It's a complex process, and even after working on magazines for nearly half a decade I don't quite understand it all!
The main thing to keep in mind regarding this subject is that books and magazines, while both printed products with pictures and words, are not the same kind of product. The methods of producing and distributing them are in some ways VASTLY different. As an example, check out the way they're presented for sale. A book is displayed on a shelf, either spine out or cover out. New books are often displayed cover out in the front of a store on a display. Sometimes books are displayed on spinners, which are really just shelves that can turn. In any store, what shelves are used to display what books is more or less left up to that store (with some exceptions—some companies by "end-caps" for their books to be displayed on shelf ends, for example).
Magazines, though, are sold on a rack. They're always displayed cover out, and therefore they take up a LOT more room. The spot on a rack that a magazine inhabits is reserved for that magazine alone, and that spot is VERY expensive to keep. It's important to keep a magazine in that spot to "save the spot," so that means that each place that sells a magazine orders more magazines than they can sell, so in theory they'll always have a few copies "holding that spot." One month later, when the new magazine comes in, those old magazines are destroyed. The money the publisher spent printing and shipping those magazines is lost, and I believe that the publisher might even have to pay for the destruction process. Books don't have this problem, really, since when a book doesn't have to "save its spot" for the next book.
There's a LOT of other ways in which the production of a magazine differs from the production of a book. Same goes for shipping, postage, distribution, reprinting, and every other facet of the industry. There are even different laws that govern magazines and books. In pretty much every case, the magazine model is less efficient and more complicated. And I think that's all a big part of the reason why times are so hard on magazines, to be honest. The internet certainly isn't helping the situation, but in large part, the magazine business model seems to me to be designed to make money for those who distribute magazines, not for those who actually make the magazines in the first place.
I miss working on Dungeon immensely. I do not miss working on a magazine at all.
