As the reach of the Internet and cell phones increases, their use as health intervention and prevention tools has been increasingly researched. To identify recent advances in technology-based HIV prevention and intervention research, we conducted a literature search in the Spring of 2007. Only a handful of articles have been published in the last year describing evaluations of technology-based HIV programs. Nonetheless, many programs have recently been funded and are being developed or imminently evaluated. Results to date suggest the Internet and cell phones are feasible technologies to deliver HIV prevention and intervention programs for some target populations. Opportunities for future research are identified, including the development of programs for populations other than men who have sex with men who also are at risk for HIV (eg, adolescents, elderly), the integration of advances from other fields, examination of the potential for using text messaging to affect HIV behavior change, and applications of Internet-based programs in developing countries.
