Change in the Popularity of Transgressive Content in Written Erotica between 2000 and 2016.

There is a widely held belief that the amount and intensity of transgressive content in pornography have been rising. Reliably assessing for such an increase, however, is complicated by methodological factors including hand-coding content using conflicting a priori definitions of what constitutes transgressive content. In response to those limitations, the present study used the results of a published empirical content analysis of ~250,000 erotic stories written over 16 years to determine if the amount or popularity of transgressive content (stories high in the themes of violence, family (incest), or BDSM) has changed in that timeframe. Results from the present study indicated no meaningful increase in either the amount of content with those themes or popularity (as measured by story views per day) of any of the three transgressive themes within the erotic narratives over the 16-year period of analysis. These results, in addition to recent research presenting similar findings within pornographic video, do not support popular perceptions that erotic material is becoming increasingly transgressive. Rather, such content within internet-based erotic material, and particularly erotic narratives, appears to be relatively consistent.
