Following the 1980s a sweeping restructuring of commercial media power has happened. While some firms have grown through expansion others extended through mergers and acquisitions. Examples are
In recent years those developments have led to the rise of transnational media giants, resulting in the domination of the global media system by about ten huge conglomerates. These have interests in numerous media industries, ranging from film production, magazines, newspapers, book publishing and recorded music to TV and radio channels and networks, but also include retail stores, amusement parks and digital media products.
Behind these firms are about three or four dozen smaller media companies, which primarily engage in local, national or niche markets. In short, the overwhelming majority of the world's content production facilities and distribution channels lies in the hands of approximately fifty enterprises.

In Sumer
Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets were used for administrative purposes. As an instrument for the administrative bodies of early empires, which began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to only very 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.

Adbusters, well known as fighters against corporate disinformation, injustices in the global economy and "physical and mental pollution", timely for the WTO Conference purchased three billboards in downtown Seattle. Featuring an image with the text "System Error - Type 2000 (progress)", the billboards were meant to challenge "... the WTO's agenda of global corporate growth and expose what isn't reflected in the United State's GNP - human and environmental capital."
At the same time RTMark went on-line with its spoof WTO website http://gatt.org. Shortly after its release WTO Director-General Mike Moore accused RTMark of attempting to "undermine WTO transparency" by copying the WTO website's design and using "domain names such as `www.gatt.org` and page titles such as 'World Trade Organization / GATT Home Page' which make it difficult for visitors to realize that these are fake pages." http://gatt.org is not the first time that RTMark has used website imitation aiming at rendering an entity more transparent.

Intellectual property, very generally, relates to the output, which result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches:
1) Industrial Property
a)
b)
c)
d) Unfair competition (trade secrets)
e) Geographical indications (indications of source and appellations of origin)
2) Copyright
The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products. Those rights apply to the intellectual creation as such, and not to the physical object in which the work may be embodied.

With the rise of a global economic system a desire to establish agreements, which protect works not only within national borders, but also within a "Union" of countries or on an international level, has been expressed. As a consequence a variety of multilateral treaties have been negotiated and adopted by governments. Those shall simplify practice through international standardization and mutual recognition of rights and duties among nations.

"All nature is merely a cipher and a secret writing."
Blaise de Vigenère
In the (dis-)information age getting information but at the same time excluding others from it is part of a power-game (keeping the other uneducated). The reason for it eventually has found an argument called security.
Compared to the frequency of its presence in articles, the news and political speeches security seems to be one of the most popular words of the 90's. It must be a long time ago when that word was only used for and by the military and the police. Today one can find it as part of every political issue. Even development assistance and nutrition programs consider it part of its work.
The so-called but also real need for information security is widespread and concerning everybody, whether someone uses information technology or not. In any case information about individuals is moving globally; mostly sensitive information like about bank records, insurance and medical data, credit card transactions, and much much more. Any kind of personal or business communication, including telephone conversations, fax messages, and of course e-mail is concerned. Not to forget further financial transactions and business information. Almost every aspect of modern life is affected.
We want to communicate with everybody - but do not want anybody to know.
Whereas the market already depends on the electronic flow of information and the digital tools get faster and more sophisticated all the time, the rise of privacy and security concerns have to be stated as well.
With the increase of digital communication its vulnerability is increasing just as fast. And there exist two (or three) elements competing and giving the term digital security a rather drastic bitter taste: this is on the one hand the growing possibility for criminals to use modern technology not only to hide their source and work secretly but also to manipulate financial and other transfers. On the other hand there are the governments of many states telling the population that they need access to any kind of data to keep control against those criminals. And finally there are those people, living between enlightening security gaps and at the same time harming other private people's actions with their work: computer hackers.
While the potential of global information is regarded as endless, it is those elements that reduce it.
There is no definite solution, but at least some tools have been developed to improve the situation: cryptography, the freedom to encode those data that one does not want to be known by everybody, and give a possibility to decode them to those who shall know the data.
During the last 80 years cryptography has changed from a mere political into a private, economic but still political tool: at the same time it was necessary to improve the tools, eventually based on mathematics. Hence generally cryptography is regarded as something very complicated. And in many ways this is true as the modern ways of enciphering are all about mathematics.
"Crypto is not mathematics, but crypto can be highly mathematical, crypto can use mathematics, but good crypto can be done without a great reliance on complex mathematics." (W.T. Shaw)

French mathematician, physicist, religious philosopher, and master of prose. He laid the foundation for the modern theory of probabilities, formulated what came to be known as Pascal's law of pressure, and propagated a religious doctrine that taught the experience of God through the heart rather than through reason. The establishment of his principle of intuitionism had an impact on such later philosophers as Jean-Jacques Rousseau and Henri Bergson and also on the Existentialists.
The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program,
