"Project Censored" Project Censored was launched at Sonoma State University (U.S.) in 1976 as an annual review of the systematic withholding of public access to important news facts by the mainstream media. The team composed of student media researcher and media analysts annually selects and publishes what they believe are the 25 most important under-covered news stories. "The essential issue raised by the project is the failure of the mass media to provide the people with all the information they need to make informed decisions concerning their own lives and in the voting booth".

The Concept of the Public Sphere According to social critic and philosopher Jürgen Habermas "public sphere" first of all means "... a domain of our social life in which such a thing as public opinion can be formed. Access to the public sphere is open in principle to all citizens. A portion of the public sphere is constituted in every conversation in which private persons come together to form a public. They are then acting neither as business or professional people conducting their private affairs, nor as legal consociates subject to the legal regulations of a state bureaucracy and obligated to obedience. Citizens act as a public when they deal with matters of general interest without being subject to coercion; thus with the guarantee that they may assemble and unite freely, and express and publicize their opinions freely." The system of the public sphere is extremely complex, consisting of spatial and communicational publics of different sizes, which can overlap, exclude and cover, but also mutually influence each other. Public sphere is not something that just happens, but also produced through social norms and rules, and channeled via the construction of spaces and the media. In the ideal situation the public sphere is transparent and accessible for all citizens, issues and opinions. For democratic societies the public sphere constitutes an extremely important element within the process of public opinion formation.

Invention According to the WIPO an invention is a "... novel idea which permits in practice the solution of a specific problem in the field of technology." Concerning its protection by law the idea "... must be new in the sense that is has not already been published or publicly used; it must be non-obvious in the sense that it would not have occurred to any specialist in the particular industrial field, had such a specialist been asked to find a solution to the particular problem; and it must be capable of industrial application in the sense that it can be industrially manufactured or used." Protection can be obtained through a patent (granted by a government office) and typically is limited to 20 years.

Virtual Private Networks Virtual Private Networks provide secured connections to a corporate site over a public network as the Internet. Data transmitted through secure connections are encrypted and therefore have to be encrypted before they can be read. These networks are called virtual because connections are provided only when you connect to a corporate site; they do not rely on dedicated lines and support mobile use.
