Mike Shatzkin's Idealogic blog is phenomenal. I've been an avid follower for years. He is a consultant to the publishing industry, so it may be a bit technical for some of my subscribers, so let me cut and paste a snippet of his preview of Digital Book World here as it relates to romance eBooks, then I'll give you a link to his blog if you want the full story.
According to Mike: "We decided to take an intensive look at the romance genre because it is often considered to be the consumer segment that has moved most rapidly into the digital future. We were fortunate to enlist the help of the ebook retailer AllRomanceEbooks.com in our investigation. They circulated a survey that got responses from almost six thousand of their customers. The results of that survey will be announced at DBW and will be followed by a panel discussion with special attention to what other genres and segments of trade publishing can learn from what has happened in the romance market.
"What caught my eye from the preliminary results was that only 4% of the ebooks All Romance sells have DRM. Since they carry the ebooks of all the major publishers, and all of those have DRM, what this statistic tells us is what a vast business exists in romance publishing outside the realm of the biggest players in the industry. I’ll leave the analysis to the experts we’ll have on stage for this discussion, but I personally wouldn’t leap to the conclusion that DRM-free is the only reason that 96% of the sales were of that category. Those books are undoubtedly cheaper as well. They may score higher on All Romance’s unique “flame” scoring system (which is all about how frequent and explicit the sex scenes are). But I would imagine that any big publisher hearing that statistic would, at the very least, have its curiosity piqued."
