Tammy Castle of James Madison University and Jenifer Lee of Texas A&M International University analyzed how prostitution is adapting to the Internet:
“Ordering sex in cyberspace: a content analysis of escort websites,” International Journal of Cultural Studies, Vol. 11, No. 1, 107-121 (2008). They report: “The purpose of this study was to uncover information about the escort agencies and escorts that utilize the internet for advertisement purposes. 
One of the goals of this research study was to describe the `typical’ escort website from the potential customer perspective and includes information on individual escorts, prices, payment options and reviews.”
