Starting in the mid 1990s today most traditional media can also be found online. The overwhelming majority of bigger newspapers and periodicals, but also radio and TV stations now complement their classic media formats with digital programming. For the most part they transform existing analogue information in digital form, with some additional features.
Especially the big media conglomerates, having realized the economic potential of the Internet, have started to get into the business of digital content. Not surprisingly their engagement in the virtual sphere has not brought much new concerning their programming. They offer entertainment, music, sports and some news channels. One of the reasons for this development might be, that the big commercial media companies are able to re-use already existing programming from their other ventures. Examples are

Here the keys for encryption and decryption differ. There needs to exist a private key, which is only known to the individual, and a public key, which is published. Every person has her or his own private key that is never published. It is used for decrypting only. Mathematically the different keys are linked to each other, still it is nearly impossible to derive the private key from the public one.
For sending a message to someone, one has to look up the other's public key and encrypt the message with it. The keyholder will use his/her private key to decrypt it. While everybody can send a message with the public key, the private key absolutely has to stay secret - and probably will.
"The best system is to use a simple, well understood algorithm which relies on the security of a key rather than the algorithm itself. This means if anybody steals a key, you could just roll another and they have to start all over." (Andrew Carol)
very famous examples for public-key systems are:
· RSA:
The RSA is probably one of the most popular public-key cryptosystems. With the help of RSA, messages can be encrypted, but also digital signatures are provided.
The mathematics behind are supposedly quite easy to understand (see:
· PGP:
PGP is a public key encryption program. Most of all it is used for e-mail encryption.
It is supposed to be quite safe - until now.
· PGPi is simply the international variation of PGP.

All of those tools, like hash functions, too, can help to enhance security and prevent crime.
They can theoretically, but sometimes they do not, as the example of the published credit card key of France in March 2000 showed.

Still, cryptography can help privacy.
On the other hand cryptography is only one element to assure safe transport of data. It is especially the persons using it who have to pay attention. A key that is told to others or a lost cryptographic key are the end of secrecy.

The secret behind all this is the conception that nothing bad could ever be referred to the own nation. All the bad words belong to the enemy, whereas the "we" is the good one, the one who never is the aggressor but always defender, the savior - not only for ones own sake but also for the others, even if they never asked for it, like the German population during World War I and II.
The spiritualization of such thinking leads to the point that it gets nearly impossible to believe that this could be un-true, a fake. To imagine injustice committed by the own nation gets more and more difficult, the longer the tactic of this kind of propaganda goes on. U.S.-Americans voluntarily believe in its politics, believing also the USA works as the police of the world, defending the morally good against those who just do not have reached the same level of civilization until today.
To keep up this image, the enemy must be portrayed ugly and bad, like in fairy-tales, black-and-white-pictures. Any connection between oneself and the enemy must be erased and made impossible. In the case of
All of this is no invention of several politicians. Huge think tanks and different governmental organizations are standing behind that. Part of their work is to hide their own work, or to deny it.

Digital technologies are used to combine previously separated communication and media systems such as telephony, audiovisual technologies and computing to new services and technologies, thus forming extensions of existing communication systems and resulting in fundamentally new communication systems. This is what is meant by today's new buzzwords "multimedia" and "convergence".
Classical dichotomies as the one of computing and telephony and traditional categorizations no longer apply, because these new services no longer fit traditional categories.
Convergence and Regulatory Institutions
Digital technology permits the integration of telecommunications with computing and audiovisual technologies. New services that extend existing communication systems emerge. The convergence of communication and media systems corresponds to a convergence of corporations. Recently,

Global networks require global technical standards ensuring the compatibility of systems. Being able to define such standards makes a corporation extremely powerful. And it requires the suspension of competitive practices. Competition is relegated to the symbolic realm. Diversity and pluralism become the victims of the globalisation of baroque sameness.
The ICT market is dominated by incomplete competition aimed at short-term market domination. In a very short time, new ideas can turn into best-selling technologies. Innovation cycles are extremely short. But today's state-of-the-art products are embryonic trash.

Although the traditional media companies first steps into the digital sphere were fairly clumsy, they have quickly learned from their mistakes and continued to enlarge their Internet presence.
During the last years many of the smaller players in the field of digital media have been driven out of competition by the huge media conglomerates. This mainly is a result of the advantages that the commercial media giants have over their less powerful counterparts:
- As engagement in online activities mostly does not lead to quick profits, investors must be able to take losses, which only powerful companies are able to.
- Traditional media outlets usually have huge stocks of digital programming, which they can easily plug into the Internet at little extra cost.
- To generate audience, the big media conglomerates constantly promote their Websites and other digital media products on their traditional media holdings.
- As possessors of the hottest "brands" commercial media companies often get premier locations from browser software makers, Internet service providers, search engines and portals.
- Having the financial resources at their disposition the big media firms are aggressive investors in start-up Internet media companies.
Commercial media companies have close and long ties to advertisers, which enables them to seize most of these revenues.

Advertising as referred to in most economic books is part of the marketing mix. Therefore advertising usually is closely associated with the aim of selling products and services. Still, developments like "branding" show a tendency towards the marketing of not only products and services, but of ideas and values. While advertising activities are also pursued by political parties, politicians and governmental as well as non-governmental organizations, most of the money flowing into the advertising industry comes from corporations. Although these clients come from such diverse fields, their intentions hardly differ. Attempting to influence the public, their main goal is to sell: Products, services, ideas, values and (political) ideology.

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.
