Late 1960s - Early 1970s: Third Generation Computers One of the most important advances in the development of computer hardware in the late 1960s and early 1970s was the invention of the integrated circuit, a solid-state device containing hundreds of transistors, diodes, and resistors on a tiny silicon chip. It made possible the production of large-scale computers (mainframes) of higher operating speeds, capacity, and reliability at significantly lower costs. Another type of computer developed at the time was the minicomputer. It profited from the progresses in microelectronics and was considerably smaller than the standard mainframe, but, for instance, powerful enough to control the instruments of an entire scientific laboratory. Furthermore operating systems, that allowed machines to run many different programs at once with a central program that monitored and coordinated the computer's memory, attained widespread use.

Content as Transport Medium for Values and Ideologies With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers. With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back.

John Dee b. July 13, 1527, London, England d. December 1608, Mortlake, Surrey English alchemist, astrologer, and mathematician who contributed greatly to the revival of interest in mathematics in England. After lecturing and studying on the European continent between 1547 and 1550, Dee returned to England in 1551 and was granted a pension by the government. He became astrologer to the queen, Mary Tudor, and shortly thereafter was imprisoned for being a magician but was released in 1555. Dee later toured Poland and Bohemia (1583-89), giving exhibitions of magic at the courts of various princes. He became warden of Manchester College in 1595.

Fair use Certain acts normally restricted by copyright may, in circumstances specified in the law, be done without the authorization of the copyright owner. Fair use may therefore be described as the privilege to use copyrighted material in a reasonable manner without the owner's consent and allows the reproduction and use of a work for limited purposes such as criticism, comment, news reporting, teaching, and research. To determine whether a use is fair or not most copyright laws consider: 1) purpose and character of the use, 2) nature of the copyrighted work, 3) amount and substantiality of the portion used, and 4) effect of the use on the potential market. Examples of activities that may be excused as fair use include: providing a quotation in a book review; distributing copies of a section of an article in class for educational purposes; and imitating a work for the purpose of parody or social commentary.
