Late 1970s - Present: Fourth Generation Computers

Following the invention of the first integrated circuits always more and more components could be fitted onto one chip. LSI (Large Scale Integration) was followed by VLSI (Very Large Scale Integration) and ULSI (Ultra-Large Scale Integration), which increased the number of components squeezed onto one chip into the millions and helped diminish the size as well as the price of computers. The new chips took the idea of the integrated circuit one step further as they allowed to manufacture one microprocessor which could then be programmed to meet any number of demands.

Also, ensuing the introduction of the minicomputer in the mid 1970s by the early 1980s a market for personal computers (PC) was established. As computers had become easier to use and cheaper they were no longer mainly utilized in offices and manufacturing, but also by the average consumer. Therefore the number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used.

Further developments included the creation of mobile computers (laptops and palmtops) and especially networking technology. While mainframes shared time with many terminals for many applications, networking allowed individual computers to form electronic co-operations. LANs (Local Area Network) permitted computers to share memory space, information, software and communicate with each other. Although already LANs could reach enormous proportions with the invention of the Internet an information and communication-network on a global basis was established for the first time.

ZaMir.net

ZaMir.net started in 1992 trying to enable anti-war and human rights groups of former Yugoslavia to communicate with each other and co-ordinate their activities. Today there are an estimated 1,700 users in 5 different Bulletin Board Systems (Zagreb, Belgrade, Ljubljana, Sarajevo and Pristiana). Za-mir Transnational Network (ZTN) offers e-mail and conferences/newsgroups. The ZTN has its own conferences, which are exchanged between the 5 BBS, and additionally offers more than 150 international conferences. ZTN aim is to help set up systems in other cities in the post-Yugoslav countries that have difficulty connecting to the rest of the world.

History

With the war in Yugoslavia anti-war and human rights groups of former Yugoslavia found it very difficult to organize and met huge problems to co-ordinate their activities due to immense communication difficulties. So in 1992 foreign peace groups together with Institutions in Ljubljana, Zagreb and Belgrade launched the Communications Aid project. Modems were distributed to peace and anti-war groups in Ljubljana, Zagreb, Belgrade and Sarajevo and a BBS (Bulletin Board System) installed.

As after spring 1992 no directs connections could be made they were done indirectly through Austria, Germany or Britain, which also enabled a connection with the worldwide networks of BBS's. Nationalist dictators therefore lost their power to prevent communication of their people. BBS were installed in Zagreb and Belgrade and connected to the APC Network and associated networks. Za-mir Transnational Network (ZTN) was born.

Strategies and Policies

With the help of ZaMir's e-mail network it have been possible to find and coordinate humanitarian aid for some of the many refugees of the war. It has become an important means of communication for humanitarian organizations working in the war region and sister organizations form other countries. It helps co-ordinate work of activists form different countries of former Yugoslavia, and it also helps to coordinate the search for volunteers to aid in war reconstruction. ZTN also helped facilitate exchange of information undistorted by government propaganda between Croatia, Serbia and Bosnia. Independent magazines like Arkzin (Croatia) and Vreme (Serbia) now publish electronic editions on ZTN.

The Role of the Media

To be able to participate in community life and make political choices citizens heavily rely on information. They need to know what is going on and the options that they should weigh, debate and act upon. An essential element for a functioning public sphere therefore is information.

Whereas formerly communication mostly happened on a face-to-face basis in large and complex societies (mass) media have evolved as the principal source of information. They act as a transport medium for the information necessary for a citizen's participation in the public sphere. Ideally there should be a wide range of media, that represent the diverse opinions and viewpoints on issues of public interest existent in a society and which are independent of the state and society's dominant economic forces.

"Project Censored"

Project Censored was launched at Sonoma State University (U.S.) in 1976 as an annual review of the systematic withholding of public access to important news facts by the mainstream media. The team composed of student media researcher and media analysts annually selects and publishes what they believe are the 25 most important under-covered news stories. "The essential issue raised by the project is the failure of the mass media to provide the people with all the information they need to make informed decisions concerning their own lives and in the voting booth".

1970s: Computer-Integrated Manufacturing (CIM)

Since the 1970s there had been a growing trend towards the use of computer programs in manufacturing companies. Especially functions related to design and production, but also business functions should be facilitated through the use of computers.

Accordingly the CAD/CAM technology, related to the use of computer systems for design and production, was developed. CAD (computer-aided design) was created to assist in the creation, modification, analysis, and optimization of design. CAM (computer-aided manufacturing) was designed to help with the planning, control, and management of production operations. CAD/CAM technology, since the 1970s, has been applied in many industries, including machined components, electronics products, equipment design and fabrication for chemical processing.

To enable a more comprehensive use of computers in firms the CIM (computer-integrated manufacturing) technology, which also includes applications concerning the business functions of companies, was created. CIM systems can handle order entry, cost accounting, customer billing and employee time records and payroll. The scope of CIM technology includes all activities that are concerned with production. Therefore in many ways CIM represents the highest level of automation in manufacturing.

An Economic and therefore Governmental Issue

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.

Virtual cartels, introduction

Among the most striking development of the 1990s has been the emergence of a global commercial media market utilizing new technologies and the global trend toward deregulation.
This global commercial media market is a result of aggressive maneuvering by the dominant firms, new technologies that make global systems cost-efficient, and neoliberal economic policies encouraged by the World Bank, IMF, WTO, and the US government to break down regulatory barriers to a global commercial media and telecommunication market.

A global oligopolistic market that covers the spectrum of media is now crystallizing the very high barriers to entry."

(Robert McChesney, author of "Rich Media, Poor Democracy")

The network structure of information and communication technologies means that even deregulated markets are not "free". The functional logic of global networks only tolerates a small number of large players. Mergers, strategic alliances, partnerships and cooperations are therefore the daily routine of the ICT business. They bypass competition and create "virtual cartels".

"Attention Brokerage"

"Attention Brokerage" is one of the latest developments in the field of online advertising. The first Web-site applying the concept of selling and buying attention is Cybergold. Users, who want to earn money have to register and then look at ads, which, of course, they have to prove by e.g. downloading software. Attention, according to this idea, represents a good, which is worth being paid for.

Virtual cartels; mergers

In parallel to the deregulation of markets, there has been a trend towards large-scale mergers which ridicules dreams of increased competition.

Recent mega-mergers and acquisitions include

SBC Communications - Ameritech, $ 72,3 bn

Bell Atlantic - GTE, $ 71,3

AT&T - Media One, $ 63,1

AOL - Time Warner, $ 165 bn

MCI Worldcom - Spring, $ 129 bn

The total value of all major mergers since the beginnings of the 1990s has been 20 trillion Dollars, 2,5 times the size of the USA's GIP.

The AOL- Time Warner reflects a trend which can be observed everywhere: the convergence of the ICT and the content industries. This represents the ultimate advance in complete market domination, and a alarming threat to independent content.

"Is TIME going to write something negative about AOL? Will AOL be able to offer anything other than CNN sources? Is the Net becoming as silly and unbearable as television?"

Economic structure; introduction



"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."

(David Sobel, Electronic Privacy Information Center)

What is the Internet?

Each definition of the Internet is a simplified statement and runs the risk of being outdated within a short time. What is usually referred to as the Internet is a network of thousands of computer networks (so called autonomous systems) run by governmental authorities, companies, and universities, etc. Generally speaking, every time a user connects to a computer networks, a new Internet is created. Technically speaking, the Internet is a wide area network (WAN) that may be connected to local area networks (LANs).

What constitutes the Internet is constantly changing. Certainly the state of the future Net will be different to the present one. Some years ago the Internet could still be described as a network of computer networks using a common communication protocol, the so-called IP protocol. Today, however, networks using other communication protocols are also connected to other networks via gateways.

Also, the Internet is not solely constituted by computers connected to other computers, because there are also point-of-sale terminals, cameras, robots, telescopes, cellular phones, TV sets and and an assortment of other hardware components that are connected to the Internet.

At the core of the Internet are so-called Internet exchanges, national backbone networks, regional networks, and local networks.

Since these networks are often privately owned, any description of the Internet as a public network is not an accurate. It is easier to say what the Internet is not than to say what it is. On 24 October, 1995 the U.S. Federal Networking Council made the following resolution concerning the definition of the term "Internet": "Internet" refers to the global information system that (i) is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons; (ii) is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and (iii) provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein." (http://www.fnc.gov/Internet_res.html)

What is generally and in a simplyfiying manner called the Internet, may be better referred to as the Matrix, a term introduced by science fiction writer William Gibson, as John S. Quarterman and Smoot Carl-Mitchell have proposed. The Matrix consists of all computer systems worldwide capable of exchanging E-Mail: of the USENET, corporate networks and proprietary networks owned by telecommunication and cable TV companies.

Strictly speaking, the Matrix is not a medium; it is a platform for resources: for media and services. The Matrix is mainly a very powerful means for making information easily accessible worldwide, for sending and receiving messages, videos, texts and audio files, for transferring funds and trading securities, for sharing resources, for collecting weather condition data, for trailing the movements of elephants, for playing games online, for video conferencing, for distance learning, for virtual exhibitions, for jamming with other musicians, for long distance ordering, for auctions, for tracking packaged goods, for doing business, for chatting, and for remote access of computers and devices as telescopes and robots remotely, e. g. The Internet is a wonderful tool for exchanging, retrieving, and storing data and sharing equipment over long distances and eventually real-time, if telecommunication infrastructure is reliable and of high quality.

For a comprehensive view of uses of the Matrix, especially the World Wide Web, see ""24 Hours in Cyberspace"

Global Data Flows

Fiber-optic cables, coaxial cables, copper wires, electric power lines, microwaves, satellite communication, mobile telephony, computer networks: Various telecommunication networks following a variety of standards with bewildering abbreviations - DSL, WAP, GSM, UMTS, Ipv4 etc. - and carrying endless flows of capital and information are the blood veins of modern societies.

In the space of flows constituted by today's global data networks the space of places is transcended. Visualizations of these global data flows show arches bridging seas and continents, thereby linking the world's centres of research and development, economics and politics. In the global "Network Society" (Manuel Castells) the traditional centres of power and domination are not discarded, in the opposite, they are strengthened and reinforced by the use of information and communication technologies. Political, economical and symbolical power becomes increasingly linked to the use of modern information and communication technologies. The most sensitive and advanced centres of information and communication technologies are the stock markets. Excluded from the network constituted by modern information and communication technologies, large parts of Africa, Asia and South America, but also the poor of industrialized countries, are ranking increasingly marginal to the world economy.

Cities are centres of communications, trade and power. The higher the percentage of urban population, the more it is likely that the telecommunications infrastructure is generally good to excellent. This goes hand in hand with lower telecommunications costs. Those parts of the world with the poorest infrastructure are also the world's poorhouse. In Bangladesh for most parts of the population a personal computer is as expensive as a limousine in European one-month's salary in Europe, they have to pay eight annual salaries. Therefore telecommunications infrastructure is concentrated on the highly industrialized world: Most telephone mainlines, mobile telephones, computers, Internet accounts and Internet hosts (computers connected to the global data networks) can be found here. The same applies to media: the daily circulation of newspapers and the use of TV sets and radios. - Telecommunication and media services affordable to most parts of the population are mostly restricted to industrialized countries.

This situation will not change in the foreseeable future: Most expenditure for telecommunications infrastructure will be restricted to the richest countries in the world. In 1998, the world's richest countries consumed 75% of all cables and wires.

Timeline of Communication Systems: Introduction

The timeline of communication systems presents a chronological overview of the most important events in the history of communication systems from the 4th millennium B.C. to the present.

It shows that from the very beginning - the first Sumerian pictographs on clay tablets to today's state-of-the-art technologies - broadband communication via fiber-optic cables and satellites - the amount of information collected, processed and stored, the capabilities to do so, as well as the capable speed of information transmission exponentially accelerate.

Advertising and the Media System

Media systems (especially broadcasting) can be classified in two different types:

Public Media Systems: Government control over broadcasting through ownership, regulation, and partial funding of public broadcasting services.

Private Media System: Ownership and control lies in the hands of private companies and shareholders.

Both systems can exist in various forms, according to the degree of control by governments and private companies, with mixed systems (public and private) as the third main kind.

Whereas public media systems are usually at least partially funded by governments, private broadcasting solely relies on advertising revenue. Still also public media systems cannot exclude advertising as a source of revenue. Therefore both types are to a certain degree dependent on money coming in by advertisers.

And this implies consequences on the content provided by the media. As the attraction of advertisers becomes critically important, interests of the advertising industry frequently play a dominant role concerning the structure of content and the creation of environments favorable for advertising goods and services within the media becomes more and more common.

Missing Labeling of Online Ads

One of the most crucial issues in on-line advertising is the blurring of the line between editorial content and ads. Unlike on TV and in the print media, where guidelines on the labeling of advertisements, which shall enable the customer to distinguish between editorial and ads, exist, similar conventions have not yet evolved for Internet content. Labeling of online advertisement up to now has remained the rare exception, with only few sites (e.g. http://www.orf.at) explicitly indicating non-editorial content.

World Wide Web (WWW)

Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and Java applets, so making multimedia content possible.

Especially on the World Wide Web, documents are often retrieved by entering keywords into so-called search engines, sets of programs that fetch documents from as many servers as possible and index the stored information. (For regularly updated lists of the 100 most popular words that people are entering into search engines, click here). No search engine can retrieve all information on the whole World Wide Web; every search engine covers just a small part of it.

Among other things that is the reason why the World Wide Web is not simply a very huge database, as is sometimes said, because it lacks consistency. There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes consoling, but threatening too.

According to the Internet domain survey of the Internet Software Consortium the number of Internet host computers is growing rapidly. In October 1969 the first two computers were connected; this number grows to 376.000 in January 1991 and 72,398.092 in January 2000.
