1960s - 1970s: Expert Systems Gain Attendance The concept of expert systems dates back to the 1960s but first gained prominence in the 1970s. Conclusive for this development were the insights of the Stanford University professor Edward Feigenbaum, who in 1977 demonstrated that the problem-solving capacity of a computer program rather is a result of the knowledge it posses, than of the applied programming techniques and formalisms. Expert systems were designed to mimic the knowledge and reasoning capabilities of a human specialist in a given domain by using (top down) artificial intelligence techniques. Made possible by the large storage capacity of the computers at the time, expert systems had the potential to interpret statistics and formulate rules. An initial use of expert systems was to diagnose and treat human physical disorders, but as its applications in the market place were extensive over the course of the following years they were also employed in fields such as stock market forecast, taxation, chemistry, and geology.

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.
