Often public relations are described as the effort to influence the public or relevant parts of it by representing self-interests to reach certain goals. This view of PR is most commonly found, when acting within the economic sphere. On the other hand organizations like the

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

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.

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.

Besides oral conversations and written language many other ways of information-transport are known: like the bush telegraph, drums, smoke signals etc. Those methods are not cryptography, still they need en- and decoding, which means that the history of language, the history of communication and the history of cryptography are closely connected to each other
The timeline gives an insight into the endless fight between enciphering and deciphering. The reasons for them can be found in public and private issues at the same time, though mostly connected to military maneuvers and/or political tasks.

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.
the word "cipher" comes from the Hebrew word "saphar", meaning "to number". Ciphers are mere substitutions. Each letter of the alphabet gets substituted; maybe by one letter or two or more.
