The Wall Street Journal weighs in on the ascendance of genre fiction over literary fiction.  Of course, this being The Wall Street Journal, the answer seems to be that the growing popularity of genre in mainstream markets is because it sells.

Something strange is happening to mainstream fiction. This summer, novels featuring robots, witches, zombies, werewolves and ghosts are blurring the lines between literary fiction and genres like science fiction and fantasy, overturning long-held assumptions in the literary world about what constitutes high and low art.

Leave it to a mainstream publication to finally catch on to something that has been happening for, oh, a few decades now, as a “summer phenomenon.”

To be fair, the author does note that such a distinction between the use of the fantastical in so-called high and low art is a modern (20th century) sensibility. Whether Lev Grossman, author of The Magicians and its (surprise, surprise) forthcoming sequel, is right that genre fiction is becoming mainstream is perhaps less a concern than whether mainstream success is ruining it for those of us who value genre precisely because it is not mainstream.  Though that may be a reverse snobbery more pretentious than the editor quoted about the forthcoming, and expected blockbuster, The Last Werewolf :

“We’re Knopf, we don’t do those kinds of books,” says editor Marty Asher. “I got completely sucked in despite my better judgment.”
