While the digital divide might bring up the idea that enterprises will be able to sell more and more computers during the next years another truth looks as if there was no hope for a certain percentage of the population to get out of their marginalization, their position of being "have nots".
Studies show that the issue of different colors of skin play a role in this, but more than "racial" issues it is income, age and education that decides about the have and have nots.
There exist ~ 103 million households in the USA.
~6 million do not even have telephone access. Why should they care about computers?
The digital divide cuts the world into centers and peripheries, not into nations, as it runs through the boarder between the North and the South as well as through nations.
The most different institutions with various interests in their background work in that field; not rarely paid by governments, which are interested in inhabitants, connected to the net and economy.

Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables
Satellite communication
Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks.
Privatization of satellite communication
Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as
Scheduled privatization of intergovernmental satellite consortia:

When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers.
As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost.
Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

"Globalization is to no small extent based upon the rise of rapid global communication networks. Some even go so far as to argue that "information has replaced manufacturing as the foundation of the economy". Indeed, global media and communication are in some respects the advancing armies of global capitalism."
(Robert McChesney, author of "Rich Media, Poor Democracy")
"Information flow is your lifeblood."
(Bill Gates, founder of Microsoft)
The usefulness of information and communication technologies increases with the number of people who use them. The more people form part of communication networks, the greater the amount of information that is produced. Microsoft founder Bill Gates dreams of "friction free capitalism", a new stage of capitalism in which perfect information becomes the basis for the perfection of the markets.
But exploitative practices have not disappeared. Instead, they have colonised the digital arena where effective protective regulation is still largely absent.
Following the dynamics of informatised economies, the consumption habits and lifestyles if customers are of great interest. New technologies make it possible to store and combine collected data of an enormous amount of people.
User profiling helps companies understand what potential customers might want. Often enough, such data collecting takes place without the customer's knowledge and amounts to spying.
"Much of the information collection that occurs on the Internet is invisible to the consumer, which raises serious questions of fairness and informed consent."

The advertising industry has always relied on media to transport their messages and disseminate them to the public. Depending on the product or service advertised and the audience targeted different media are used. Besides cinema and outdoor advertising (posters etc.) the huge majority of ads is placed within the classical media landscape, which includes TV, newspapers, magazines and radio.
Whereas in most cases only a relatively small fraction of advertising budgets is spent on cinema, outdoor and radio advertising, newspapers, magazines and TV account for more than two thirds of the money spent on ads. Still with the growing popularity of new media advertisers and marketers have recently also discovered digital networks and especially the Internet for their purposes.

Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets are used for administrative purposes. As an instrument for the administrative bodies of early empires, who began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to a few. Being more or less separated tasks, writing and calculating converge in today's computers.
Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China.
Fiber-optic cable networks may become the dominant method for high-speed Internet connections. Since the first fiber-optic cable was laid across the Atlantic in 1988, the demand for faster Internet connections is growing, fuelled by the growing network traffic, partly due to increasing implementation of corporate networks spanning the globe and to the use of graphics-heavy contents on the
Fiber-optic cables have not much more in common with copper wires than the capacity to transmit information. As copper wires, they can be terrestrial and submarine connections, but they allow much higher transmission rates. Copper wires allow 32 telephone calls at the same time, but fiber-optic cable can carry 40,000 calls at the same time. A capacity,
Copper wires will not come out of use in the foreseeable future because of technologies as
