Advertising, Public Relations and Think Tanks Although advertising, public relations and think tanks at first seem to have nothing in common, after a closer look certain similarities arise. The first thing which can be noted is that public relations and the advertising industry, as well as - especially conservative - think tanks like the Heritage Foundation or the Brookings Institute have strong ties to corporate firms. Whereas the connection between the advertising and public relations industry and corporations is based on a consultant - client relation many think tanks heavily rely on corporate funding to pursue their activities. Therefore the interests of corporate firms are to an - in some cases considerable - extent reflected in their activities. Furthermore the aims of public relations and advertising firms and think tanks are not too different. Their main goal is to sell ideas and values. Albeit it sometimes makes the impression, as if only products, services and understanding (in the case of public relations) are sold, for the greater part the only thing being marketed is (political) ideology.

Examples of Mainly Corporate Funded Think Tanks: Cato Institute Founded in 1977 the Cato Institutes 1998 budget made up US$ 11 million. Its funding consists of corporate and private donations (especially from corporations and executives in the highly regulated industries of financial services, telecommunications and pharmaceuticals industries) and sales of publications. Catos corporate donors include tobacco firms: Philip Morris (Rupert Murdoch sits on Philip Morris board of directors) and R.J. Reynolds. Financial firms: American Express, Chase Manhattan Bank, Chemical Bank, Citicorp/Citibank, Commonwealth Fund, Prudential Securities and Salomon Brothers. Energy conglomerates: Chevron Companies, Exxon Company, Shell Oil Company and Tenneco Gas, as well as the American Petroleum Institute, Amoco Foundation and Atlantic Richfield Foundation. Furthermore the Cato Institute is funded by pharmaceutical firms: Eli Lilly & Company, Merck & Company and Pfizer, Inc., foundations, like Koch, Lambe and Sarah Scaife and companies from the telecommunications sector: Bell Atlantic Network Services, BellSouth Corporation, Microsoft, NYNEX Corporation, Sun Microsystems and Viacom.

Neural network A bottom-up artificial intelligence approach, a neural network is a network of many very simple processors ("units" or "neurons"), each possibly having a (small amount of) local memory. The units are connected by unidirectional communication channels ("connections"), which carry numeric data. The units operate only on their local data and on the inputs they receive via the connections. A neural network is a processing device, either an algorithm, or actual hardware, whose design was inspired by the design and functioning of animal brains and components thereof. Most neural networks have some sort of "training" rule whereby the weights of connections are adjusted on the basis of presented patterns. In other words, neural networks "learn" from examples and exhibit some structural capability for generalization.

ARPAnet ARPAnet was the small network of individual computers connected by leased lines that marked the beginning of today's global data networks. Being an experimental network mainly serving the purpose to test the feasibility of wide area networks, the possibility of remote computing, it was created for resource sharing between research institutions, not for messaging services like E-mail. Although research was sponsored by US military, ARPAnet was not designed for directly martial use but to support military-related research. In 1969 ARPANET went online and links the first two computers, one of them located at the University of California, Los Angeles, the other at the Stanford Research Institute. But ARPAnet has not become widely accepted before it was demonstrated in action to a public of computer experts at the First International Conference on Computers and Communication in Washington, D. C. in 1972. Before it was decommissioned in 1990, NSFnet, a network of scientific and academic computers funded by the National Science Foundation, and a separate new military network went online in 1986. In 1988 the first private Internet service providers offered a general public access to NSFnet. Beginning in 1995, after having become the backbone of the Internet in the USA, NSFnet was turned over to a consortium of commercial backbone providers. This and the launch of the World Wide Web added to the success of the global data network we call the Net. In the USA commercial users already outnumbered military and academic users in 1994. Despite the rapid growth of the Net, most computers linked to it are still located in the United States.
