Highlights on the Way to a Global Commercial Media Oligopoly: 1990s -1994 Viacom multimedia and industrial corporation takes control of Paramount Communications for US$ 9.6 billion, as well as Blockbuster Entertainment, a huge video store chain, for US$ 8.4. billion. 1995 Entertainment giant Disney buys Capital Cities-ABC for US$ 19 billion. The industrial and broadcasting company Westinghouse Corp. buys out CBS for US$ 5.4 billion. In a US$ 7.2 billion deal, Time Warner acquires Turner Communications, owner of prime cable TV channels CNN, TBS and TNT and a major classic American film library. 1996 Westinghouse/CBS buys Infinity Broadcasting's large group of radio stations. Murdoch and News Corp. acquire ten more TV stations and TV production studios with the US$ 2.5 billion purchase of New World Communications Group. Viacom buys half of UPN-TV network, adding that to its other holdings, which include eleven TV stations, along with MTV, VH-1, and other cable TV channels and Paramount movie studios. 1997 Radio Groups Chancellor Media and Evergreen merge and are linked by ownership with Capstar Broadcasting; they also buy ten radio stations from Viacom. By mid-1997 Chancellor/Capstar controls no fewer than 325 radio stations around the United States. Chancellor/Capstar's controlling ownership group, Hicks Muse Tate & Furst, buys the seventh largest radio group, SFX, adding another seventy-two radio stations, making a total of nearly four hundred stations controlled by this one source. Westinghouse-CBS buys out American Radio Systems, the fourth largest radio chain in total audience, which gives Westinghouse-CBS over 170 radio stations with a total audience nearly equal to that of the Chancellor/Capstar group. Giant European-based print and electronic publishing and data base corporations Reed Elsevier and Wolters Kluwer merge. 1998 Bertelsmann buys the Random House-Alfred A. Knopf-Crown Publishing group of book publishers from Newhouse/Advance Publications, adding to its Bantam-Doubleday-Dell publishing group and giving Bertelsmann by far the largest English-language publishing operations. 1999 AOL, the worlds leading Internet service provider and Time Warner, the worlds leading classical media company merge in a US$ 243.3 billion deal.

Asymmetric or Public-Key-Cryptosystems 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: http://world.std.com/~franl/crypto/rsa-guts.html. · 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. for further information about the RSA and other key-systems visit the RSA homepage: http://www.rsa.com/rsalabs/faq/ http://www.rsa.com/rsalabs/faq/questions.html or: http://www.pgpi.org 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. For more information see: http://news.voila.fr/news/fr.misc.cryptologie 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.

Advertising and the Content Industry - The Coca-Cola Case Attempts to dictate their rules to the media has become a common practice among marketers and the advertising industry. Similar as in the Chrysler case, where the company demanded that magazines give advance notice about controversial articles, recent attempts to put pressure on content providers have been pursued by the Coca-Cola Company. According to a memo published by the New York Post, Coca-Cola demands a free ad from any publication that publishes a Coke ad adjacent to stories on religion, politics, disease, sex, food, drugs, environmental issues, health, or stories that employ vulgar language. "Inappropriate editorial matter" will result in the publisher being liable for a "full make good," said the memo by Coke advertising agency McCann-Erickson. Asked about this practice, a Coke spokes person said the policy has long been in effect. (Source: Odwyerpr.com: Coke Dictates nearby Editorial. http://www.odwyerpr.com)

1913: Henry Ford and the Assembly Line Realizing that he'd need to lower costs Henry Ford (Ford Motor Company) was inspired to create a more efficient way to produce his cars. Looking at other industries he and his team found four principles, which furthered their goal: interchangeable parts, continuous flow, division of labor, and reducing wasted effort. The use of interchangeable parts meant making the individual pieces of the car the same every time. Therefore the machines had to be improved, but once they were adjusted, they could be operated by a low-skilled laborer. To reduce the time workers spent moving around Ford refined the flow of work in the manner that as one task was finished another began, with minimum time spent in set-up. Furthermore he divided the labor by breaking the assembly of the legendary Model T in 84 distinct steps. Frederick Taylor, the creator of "scientific management" was consulted to do time and motion studies to determine the exact speed at which the work should proceed and the exact motions workers should use to accomplish their tasks. Putting all those findings together in 1913 Ford installed the first moving assembly line that was ever used for large-scale manufacturing. His cars could then be produced at a record-breaking rate, which meant that he could lower the price, but still make a good profit by selling more cars. For the first time work processes were largely automated by machinery.

Expert system Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to artificial intelligence. The three main elements of expert systems are: (1) an interface which allows interaction between the system and the user, (2) a database (also called the knowledge base) which consists of axioms and rules, and (3) the inference engine, a computer program that executes the inference-making process. The disadvantage of rule-based expert systems is that they cannot handle unanticipated events, as every condition that may be encountered must be described by a rule. They also remain limited to narrow problem domains such as troubleshooting malfunctioning equipment or medical image interpretation, but still have the advantage of being much lower in costs compared with paying an expert or a team of specialists.

Microsoft Corporation Founded by Bill Gates and Paul Allen and headquartered in Redmond, USA, Microsoft Corporation is today's world-leading developer of personal-computer software systems and applications. As MS-DOS, the first operating system released by Microsoft, before, Windows, its successor, has become the de-facto standard operating system for personal computer. According to critics and following a recent court ruling this is due to unfair competition. http://www.microsoft.com For more detailed information see the Encyclopaedia Britannica: http://www.britannica.com/bcom/eb/article/4/0,5716,1524+1+1522,00.html http://www.microsoft.com/ http://www.britannica.com/bcom/eb/article/4/0...
