Okay, not quite millions, but it's no secret that in the modern publishing era, romance novels outsell every other genre, and women make up a majority of book buyers in nearly every category of books except for war, science fiction, and sports. With the romance genre alone, women make up 84% of the purchasing market (note: I'm surprised it's that low, I didn't realize that men make up 16% of romance readers).
Ebooks haven't changed that trend too much. The overall male/female split of book purchasers remain the same, women are buying a lot more of their books as ebooks. In fact, ebooks have increased the sale of romance novels, but not necessarily in a way that has increased the profit of publishers. In fact, publishers are feeling the pain of ebooks because many authors, especially in the romance genre are self-publishing or publishing straight through Amazon, choosing to cut out the middle man. This lowers the costs of publishing and creates a higher profit margin for authors.
