There are now over one million online users below the age of eighteen. A recently pronounced goal in the United States for the National Information Infrastructure (NIl) is to enable it to provide a level of education to all students that surpasses the highest levels of education available today. Throughout the history of the Nil, education and research were key motivations for the development of the technology, fIrst as the ARPANET, then the Internet, the NREN, the NIl, and as part of the United States Department of Education project GOALS2000. Many recent initiatives have focused on the educational capabilities of these networks for K-12 students. In addition, a signifIcant reason for the presence of young people on the Internet has been the explosive growth of online services and Internet access, especially through services such as America Online (AOL), CompuServe, and Prodigy. Ironically, this surge of new users has also brought an increase in the availability of adult-oriented content and services, much of which is considered inappropriate for young people.
