September 2001. Estimates of the total number of Web pages vary,
but a figure of 2 billion is a reasonable estimate of the number
of Web pages that can be reached, in theory, by standard search
engines. We need not make a specific finding as to a figure, for
by any measure the Web is extremely vast, and it is constantly
growing. The indexable Web is growing at a rate of approximately
1.5 million pages per day. The size of the un-indexable Web, or
the "Deep Web," while impossible to determine precisely, is
estimated to be two to ten times that of the publicly indexable
Web.


In addition to growing rapidly, Web pages and sites are
constantly being removed, or changing their content. Web sites
or pages can change content without changing their domain name
addresses or IP addresses. Individual Web pages have an average
life span of approximately 90 days.
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
