On-line Advertising Revenues Although Internet advertising only really started in 1994, revenues showed a steady and fast growth. In 1997 US$ 906.5 million were spent on on-line advertising. Compared with advertising revenue for the television industry in equivalent dollars for its third year, the Internet was slightly ahead, at US$ 907 million compared to television's US$ 834 million. 1998 on-line advertising grew by 112 percent to US$ 1.92 billion in revenues, and is on track to hit US$ 4 billion in 1999, which would put Internet advertising at about 2 percent of the U.S. ad market.

The Role of the Media To be able to participate in community life and make political choices citizens heavily rely on information. They need to know what is going on and the options that they should weigh, debate and act upon. An essential element for a functioning public sphere therefore is information. Whereas formerly communication mostly happened on a face-to-face basis in large and complex societies (mass) media have evolved as the principal source of information. They act as a transport medium for the information necessary for a citizen's participation in the public sphere. Ideally there should be a wide range of media, that represent the diverse opinions and viewpoints on issues of public interest existent in a society and which are independent of the state and society's dominant economic forces. | ||||||||||||||||||||||||||

FREEnet (The Network for Research, Education and Engineering) FREEnet is an academic and research network, interconnecting computer networks of research institutes of the Russian Academy of Sciences, universities, colleges, and other research and academic institutions. It was established in 1991 by the N.D. Zelinsky Institute of Organic Chemistry at the Center of Computer Assistance to Chemical Research. It provides its more than 350 members of the academic and educational community with all types of basic Internet services and various information services. Strategies and Policies FREEnets general intention is to become a backbone infrastructure providing: Open networking services for efficient access to the network and information resources located both in Russia and all over the Internet. Reliable network connectivity for research, academic and educational communities in Russia and abroad. Worldwide access to science and information resources of the Russian Academy of Sciences, universities and colleges in Russia. Assistance to the progress of Russian based fundamental research. Assistance to the development and application of modern information technologies in education. | ||||||||||||||||||||||||||

In Search of Reliable Internet Measurement Data Newspapers and magazines frequently report growth rates of Internet usage, number of users, hosts, and domains that seem to be beyond all expectations. Growth rates are expected to accelerate exponentially. However, Internet measurement data are anything thant reliable and often quite fantastic constructs, that are nevertheless jumped upon by many media and decision makers because the technical difficulties in measuring Internet growth or usage are make reliable measurement techniques impossible. Equally, predictions that the Internet is about to collapse lack any foundation whatsoever. The researchers at the Size and Growth In fact, "today's Internet industry lacks any ability to evaluate trends, identity performance problems beyond the boundary of a single ISP (Internet service provider, M. S.), or prepare systematically for the growing expectations of its users. Historic or current data about traffic on the Internet infrastructure, maps depicting ... there is plenty of measurement occurring, albeit of questionable quality", says K. C. Claffy in his paper Internet measurement and data analysis: topology, workload, performance and routing statistics (http://www.caida.org/Papers/Nae/, Dec 6, 1999). Claffy is not an average researcher; he founded the well-known So his statement is a slap in the face of all market researchers stating otherwise. In a certain sense this is ridiculous, because since the inception of the So what are the reasons for this inability to evaluate trends, identity performance problems beyond the boundary of a single ISP? First, in early 1995, almost simultaneously with the worldwide introduction of the "There are many estimates of the size and growth rate of the Internet that are either implausible, or inconsistent, or even clearly wrong", K. G. Coffman and Andrew, both members of different departments of What is measured and what methods are used? Many studies are devoted to the number of users; others look at the number of computers connected to the Internet or count You get the clue of their focus when you bear in mind that the Internet is just one of many networks of networks; it is only a part of the universe of computer networks. Additionally, the Internet has public (unrestricted) and private (restricted) areas. Most studies consider only the public Internet, Coffman and Odlyzko consider the long-distance private line networks too: the corporate networks, the Hosts The Despite the small sample, this method has at least one flaw: Internet Weather Like daily weather, traffic on the Internet, the conditions for data flows, are monitored too, hence called Internet weather. One of the most famous Internet Hits, Page Views, Visits, and Users Let us take a look at how these hot lists of most visited Web sites may be compiled. I say, may be, because the methods used for data retrieval are mostly not fully disclosed. For some years it was seemingly common sense to report requested files from a Web site, so called "hits". A method not very useful, because a document can consist of several files: graphics, text, etc. Just compile a document from some text and some twenty flashy graphical files, put it on the Web and you get twenty-one hits per visit; the more graphics you add, the more hits and traffic (not automatically to your Web site) you generate. In the meantime page views, also called page impressions are preferred, which are said to avoid these flaws. But even page views are not reliable. Users might share computers and corresponding Especially the editors of some electronic journals (e-journals) rely on page views as a kind of ratings or circulation measure, Rick Marin reports in the More advanced, but just slightly better at best, is counting visits, the access of several pages of a Web site during one session. The problems already mentioned apply here too. To avoid them, newspapers, e.g., establish registration services, which require password authentication and therefore prove to be a kind of access obstacle. But there is a different reason for these services. For content providers users are virtual users, not unique persons, because, as already mentioned, computers and For If you like to play around with Internet statistics instead, you can use Robert Orenstein's Measuring the Density of Measuring the Density of Dodge and Shiode used data on the ownership of IP addresses from | ||||||||||||||||||||||||||
