It's more like an architecture than a physical entity. The Internet doesn't start in one place and travel straightforwardly to another. It isn't operated by a central authority, as a television network or cable system is, and it doesn't even have its own dedicated channels of operation, as radio stations do. Instead it is a global information system, inviting and making possible the expression of multiple points of view, simultaneously and instantaneously, in ways other traditional systems simply can't match. The Internet also differs from the traditional mass media in that it has the potential to be truly global and essentially timeless.
Time zones are also irrelevant on the Internet.
These days some companies are providing products as well as services 24 hours a day, in locations around the world, because data can be handed along the time spectrum via the Net. The Tokyo engineer also works on the modifications for eight hours, and then emails his work off to yet another a colleague in Bonn, who finishes the job just as the American is arriving at the office for the next day's work. Most important, the Internet is decentralized. It is constantly expanding and open to any user or service provider. Consider, for example, recent efforts by both state and federal policymakers to restrict certain content on the Web.
