The Internet is not a company or organization and is not regulated by the FCC or any other government agency. It's a loose federation of computer sites that agree to link their computers together. The Internet started in the 1960s as a Defense Department experiment, and until 1990 it was purely a network of universities and research labs. Nowadays, most people access the Internet through commercial access providers such as CompuServe and America OnLine, which were originally separate networks. All of these rely on the rapid forwarding of data from site to site.
Messages take whatever path is convenient at the time.
Because there's no central node, censoring the content of messages is physically impossible. The diagram shows how a message might go from The University of Georgia to Phoenix Computer Specialists in Arizona. Each site picks up each data packet and passes it on. Successive packets in the same session don't necessarily follow the same path. In the early days of the net, sites transmitted information for each other free of charge, voluntarily.
