The Internet allows multimedia documents to be moved between any two computers, using an "internetwork" of relaying computers. Multimedia documents can be found by those seeking information using a web browser to "pull" information off the "World Wide Web," or using an e-mail system to "push" information to those currently uninterested or unaware of an issue.
The Internet has been called an "engine of empowerment" that creates healthy "virtual communities." Others, however, say it increases may social and health-related problems, including individual isolation and risky sexual practices by fragmenting relationships and by increasing the anonymous distribution and viewing of pornographic material. These seemingly contradictory outcomes can be reconciled in understanding that the Internet, like any communications technology, amplifies the intentions of its users. It amplifies these intentions by primarily increasing the "reach" of both the sender and receiver, who often share a common interest. As a result, its use may only increase the sharing of information that reinforces and amplifies preexisting life patterns.
