Last time, I spoke about the dominance of the romance genre in book sales accounting for 21% of the book market. Since that time, there have been some requests for statistics as to the sales figures for other genres. The total net revenue for books in the U.S. was around $6.31 billion. Of that, Science Fiction/Fantasy accounts for $495 million or 7.8 % of the market. Classic Literary Fiction is about $448 million or 7.1 % of the market. I was rather surprised to discover that Mystery, which is at $422 million, is only 6.7% of the market. And perhaps the newest and fastest growing genre – Graphic Novels make up a not insignificant 2% of overall book sales, bringing in $128 million and those figures are expected to increase in the years to come.
