3.  The Amount of Sexually Explicit Material on the Web

There is a vast amount of sexually explicit material available via the Internet and

the Web.  Sexually explicit material on the Internet is easy to access using any public

search engine, such as, for example, Google or AltaVista. Although much of the sexually

explicit material available on the Web is posted on commercial sites that require viewers

to pay in order to gain access to the site, a large number of sexually explicit sites may be

accessed for free and without providing any registration information.  Most importantly,

some Web sites that contain sexually explicit content have innocuous domain names and

therefore can be reached accidentally.  A commonly cited example is

http://www.whitehouse.com.  Other innocent sounding URLs that retrieve graphic,

sexually explicit depictions include http://www.boys.com, http://www.girls.com,

http://www.coffeebeansupply.com, and http://www.BookstoreUSA.com.  Moreover,

commercial Web sites that contain sexually explicit material often use a technique of

attaching pop up windows to their sites, which open new windows advertising other

sexually explicit sites without any prompting by the user.  This technique makes it

difficult for a user quickly to exit all of the pages containing sexually explicit material,

whether he or she initially accessed such material intentionally or not.
