Definition

During the last 20 years the old Immanuel Wallerstein-paradigm of center - periphery and semi-periphery found a new costume: ICTs. After Colonialism, Neo-Colonialism and Neoliberalism a new method of marginalization is emerging: the digital divide.

"Digital divide" describes the fact that the world can be divided into people who
do and people who do not have access to (or the education to handle with) modern information technologies, e.g. cellular telephone, television, Internet. This digital divide is concerning people all over the world, but as usually most of all people in the formerly so called third world countries and in rural areas suffer; the poor and less-educated suffer from that divide.
More than 80% of all computers with access to the Internet are situated in larger cities.

"The cost of the information today consists not so much of the creation of content, which should be the real value, but of the storage and efficient delivery of information, that is in essence the cost of paper, printing, transporting, warehousing and other physical distribution means, plus the cost of the personnel manpower needed to run these `extra' services ....Realizing an autonomous distributed networked society, which is the real essence of the Internet, will be the most critical issue for the success of the information and communication revolution of the coming century of millennium."
(Izumi Aizi)

Advertisers and Marketers Perspective

With the rapid growth of the Internet and its audience advertisers now have a new medium at their disposal. The placement of the first banner ads in 1994 marks the birth of Internet advertising. Although the advertising industry at first hesitated to adopt the new medium, two facts brushed away their doubts:

Migrating Television Audiences: The increased use of the Internet led people to redistribute their time budget. Whereas some cut down on eating and sleeping, more than a third reduced watching television and instead uses the WWW.

Interesting Internet Demographics: While methodologies and approaches of research organizations studying the demographic composition of the Internet vary, the findings are relatively consistent: Internet users are young, well educated and earn high incomes.

Considering those findings, the Internet in the first place seems to become inevitable to be included in media planning, as part of the audience shifts from TV to the WWW, and secondly, because demographics of the Internet user population are irresistible for marketers.

Acessing the Internet

The Net connections can be based on wire-line and wireless access technolgies.

Wire-line access

Wire-less access

copper wires

Satellites

coaxial cables

mobile terrestrial antennas

electric power lines

fixed terrestrial antennas

fiber-optic cables







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 ISDN lines, etc., to an Internet Service Provider, from there, via fibre-optic cables, to the nearest Internet exchange, and on into a backbone network, tunneling across the continent und diving through submarine fibre-optic cables across the Atlantic to another Internet exchange, from there, via another backbone network and across another regional network to the Internet Service Provider of the supposed message recipient, from there via cables and wires of different bandwidth arriving at its destination, a workstation permanently connected to the Internet. Finally a sound or flashing icon informs your virtual neighbor that a new message has arrived.

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 Intelsat, Intersputnik and Inmarsat.

Scheduled privatization of intergovernmental satellite consortia:

Satellite consortia

Year of foundation

Members

Scheduled date for privatization

Intelsat

1964

200 nations under the leadership of the USA

2001

Intersputnik

1971

23 nations under the leadership of Russia

?

Inmarsat

1979

158 nations (all members of the International Maritime Organization)

privatized since 1999

Eutelsat

1985

Nearly 50 European nations

2001



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.

Vinton Cerf

Addressed as one of the fathers of the Internet, Vinton Cerf together with Robert Kahn developed the TCP/IP protocol suite, up to now the de facto-communication standard for the Internet, and also contributed to the development of other important communication standards. The early work on the protocols broke new ground with the realization of a multi-network open architecture.

In 1992, he co-founded the Internet Society where he served as its first President and later Chairman.

Today, Vinton Cerf is Senior Vice President for Internet Architecture and Technology at WorldCom, one of the world's most important ICT companies
