The following article link was posted by Fox News as a surprised reaction to the moniker "chick nonfiction." While not the most original label for a type of nonfiction material (I prefer "womyn truth books), this should not shock anyone too much in a market where Eat, Pray, Love got published and made into a major motion picture. Every item you see is marketed to some demographic specifically, but not so much that it can't get others involved.
I imagine them wondering the aisles of a nonfiction section. "Holy crap, why do the cookbooks have pictures of cute or grandmotherly-type women cooking on them?" "R. Lee Ermy is on so many military books!" "The Backstreet Boys had a crafting book?"
