OREANDA-NEWS. July 06, 2016. With its handsome sales figures, ardent digital audience and swelling new sub-genres, today’s Romance book market presents an alluring opportunity for publishers.

According to Nielsen data, the romance market is big and strapping across both traditional and emerging formats: The most popular romance title in print last year, E.L. James’ Grey, alone sold 1.9 million units. More than 44 million print and 28 million electronic Romance books were sold in 2015.

The Romance genre accounted for nearly 20% of all e-book sales in the U.S. in 2015, making it the most digitally driven literary genre. Amazon was the top retailer of Romance e-books, and the median digital title cost about \\$5, a lower price point that a typical printed adult fiction title.

The relatively low cost and easy accessibility of e-books, combined with an increasingly younger fan base, appears to suggest that Romance readers are especially open to trying new titles and niches within the genre.

So what does this digital-savvy, adventurous audience like to read? Driven in part by the success of the Fifty Shades series, erotica has posted steady double-digit (10%) year-over-year sales growth since 2014, while suspense titles (16%) have also seen consistent gains over the past three years.

The biggest increases in sales since 2014 have occurred in sub-genres that haven’t typically been part of the Romance mainstream. Romantic comedy sales grew by 357% over the past three years and science fiction romance grew sales by 336%.
