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.

Public Relations and Propaganda Public relations usually is associated with the influencing of public opinion. Therefore it has subsequently been linked with propaganda. Using one of the many definitions of propaganda "... the manipulation of symbols as a means of influencing attitudes on controversial matters" (Harold D. Lasswell), the terms propaganda and PR seem to be easily interchangeable. Still many authors explicitly distinguish between public relations, advertising and propaganda. Unlike PR, which is often described as objective and extensive information of the public, advertising and propaganda are associated with manipulative activities. Nevertheless to treat public relations and propaganda as equivalents stands in the tradition of PR. Edward L. Bernays, one of the founders of public relations wrote "The only difference between propaganda and education, really, is the point of view. The advocacy of what we believe in is education. The advocacy of what we don't believe is propaganda." Also institutions like the German Bundeswehr use the terms publics relations and propaganda synonymously. After a 1990 legislation of the former minister of defense Stoltenberg, the "psychological influence of the enemy" was ceased during peace time and the Academy for Psychological Defense renamed to Academy for Information and Communication, among other things responsible for scientific research in the field of public relations.

Philip M. Taylor Munitions of the Mind. A history of propaganda from the ancient world to the present era. Manchester 1995 (2nd ed.) This book gives a quite detailed insight on the tools and tasks of propaganda in European and /or Western history. Starting with ancient times the author goes up till the Gulf War and the meaning of propaganda today. In all those different eras propaganda was transporting similar messages, even when technical possibilities had not been fairly as widespread as today. Taylor's book is leading the reader through those different periods, trying to show the typical elements of each one.

Whitfield Diffie Whitfield Diffie is an Engineer at Sun Microsystems and co-author of Privacy on the Line (MIT Press) in 1998 with Susan Landau. In 1976 Diffie and Martin Hellman developed public key cryptography, a system to send information without leaving it open to be read by everyone.

PGP A cryptographic software application that was developed by Phil Zimmerman at the Massachusetts Institute of Technology. Pretty Good Privacy (PGP) is a cryptographic product family that enables people to securely exchange messages, and to secure files, disk volumes and network connections with both privacy and strong authentication.
