Is the Internet for Porn? An Insight Into the Online Adult Industry Gilbert Wondracek1 , Thorsten Holz1 , Christian Platzer1 , Engin Kirda2 , and Christopher Kruegel3 Secure Systems Lab, Technical University Vienna Abstract University of California, Santa Barbara Apparently, even roughly estimating the size of the Internet porn industry is non-trivial, as different sources [2, 10, 28] indicate a yearly total revenue that ranges from 1 to 97 billion USD. Yet, even the lowest of these estimates hints at the economic significance of this market. Interestingly, however, to the best of our knowledge, no study has yet been published that analyzes the economical and technological structure of this industry from a security point of view. In this work, we aim at answering the following questions: Which economic roles exist in the online adult industry? Our analysis shows that there is a broad array of economic roles that web sites in this industry can assume. Apart from the purpose of selling pornographic media over the Internet, there are much less obvious and visible business models in this industry, such as traffic trading web sites or cliques of business competitors who cooperate to increase their revenue. We identify, in this paper, the main economic roles of the adult industry and show the associated revenue models, organizational structures, technical features and interdependencies with other economic actors.
