"Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break." (David Kahn)
The variants of encryption systems are endless.
For deciphering there exists always the same game of trial and error (first guessing the encryption method, then the code). A help to do so is pruning. Once, after a more or less long or short period a code/cipher breaks. Monoalphabetic ciphers can be broken easily and of course are no longer used today but for games.

Mabye the thorniest ethical problem in Web publishing are links. "We need some sort of universal designation for links that have been purchased as opposed to links that belong to traditional editorial... There's no other medium - with the possible exception of late-late-night television - where this sort of blurring of advertising and editorial is tolerated.", says Steve Johnson from FEED.

John W. Hill opened the doors of his first public relations office in 1927 in Cleveland, Ohio. His early clients were banks, steel manufacturers, and other industrial companies in the Midwest.

In 1952, Hill and Knowlton became the first American public relations consultancy to recognize the business communication implications engendered by formation of the European Economic Community. Hill and Knowlton established a network of affiliates across Europe and by the middle of the decade had become the first American public relations firm to have wholly-owned offices in Europe. Hill and Knowlton, a member of the WPP Group integrated communications services family, has extensive resources and geographic coverage with its 59 offices in 34 countries. Hill and Knowlton is known for its hard-hitting tactics and said to have connections with intelligence services.
Seagram is the largest producer and marketer of distilled spirits in the world. It is headquartered in Montreal, Que. The company began when Distillers Corp., Ltd., a Montreal distillery owned by Samuel Bronfman, acquired Joseph E. Seagram & Sons in 1928. Under the leadership of the founder's son, Edgar M. Bronfman, who became head of the company in 1971, the firm diversified during the 1950s and '60s from its original base of blended whiskies into the production and marketing of scotch, bourbon, rum, vodka, gin, and many different wines. It also expanded into the European, Latin American, East Asian, and African markets with its products. The company adopted its present name in 1975. It produces more than 400 different brands of distilled spirits and wines. Edgar M. Bronfman, Jr., took over as head of the company in 1989. Seagram in 1995 purchased MCA Inc., a media and entertainment firm, from the Matsushita Electric Industrial Company.

By name PAPA DOC, president of Haiti whose 14-year regime was of unprecedented duration in that country. A supporter of President Dumarsais Estimé, Duvalier was appointed director general of the National Public Health Service in 1946. He was appointed underminister of labour in 1948 and the following year became minister of public health and labour, a post that he retained until May 10, 1950, when President Estimé was overthrown by a military junta under Paul E. Magloire, who was subsequently elected president. By 1954 he had become the central opposition figure and went underground. Duvalier was elected president in September 1957. Setting about to consolidate his power, he reduced the size of the army and organized the Tontons Macoutes ("Bogeymen"), a private force responsible for terrorizing and assassinating alleged foes of the regime. Late in 1963 Duvalier moved further toward an absolutist regime, promoting a cult of his person as the semi divine embodiment of the Haitian nation. In April 1964 he was declared president for life. Although diplomatically almost completely isolated, excommunicated by the Vatican until 1966 for harassing the clergy, and threatened by conspiracies against him, Duvalier was able to stay in power longer than any of his predecessors.
