The Internet is a global network of computers linked by high-speed datalines and wireless systems. It was established in 1969 as a militarycommunications system. It allows individuals to access information from manysources using a computer.[3] The use of the Internet more than doubled in sizein 1995 and has done so every year since 1988, becoming the fastest-growingcommunications medium ever.Measuring the real Internet population, its use disaggregated by sex,the size of the potential demand and the trends for growth is difficult, andresults are often contradictory. The special nature of the medium and itsrapid development throw up new figures every day. Some sources have estimatedthat a new web site is launched on the Internet every four seconds.
It is difficult to gauge reliably the size and demographic profile ofusers, because user-tracking software remains inadequate, and it is notpossible, for example, to distinguish new "hits" from repeat visits to a site.Nevertheless. it is estimated that the Internet links 50 million users in morethan 80 countries worldwide. Some consider that this will increase to around300 million in the next five years. [4]
The WWW is the fastest-growing segment of the Internet, growing at rateof 3,000 per cent every year. It allows exchange of multimedia data (text,audio, video, graphics and animation) between users connected to the Internetusing hypertext links.
In the United States, which has taken the lead in the market, datasuggest that there are between 16.4 million[5] and 37 million people (in theU.S. and Canada) [6] who have access to the Internet, spending an average of 5hours 28 minutes per week on line. Users in Europe are 5 to 8 million ormore. In Japan, there are approximately 4 million users. [7] In Latin America,electronic mail is rapidly replacing regular mail, as it is much moreefficient. [8] In Africa, new Internet domains have been registered in the lastyear in Angola, Benin, Burkina Faso, Djibouti and Madagascar. In countriessuch as Kenya, Namibia and Senegal, the number of domains is rising rapidly.Kenya has around 133, compared with South Africa's more than 83,000. [9]
In terms of market size, the global Internet market is expected to soarto $200 billion by the year 2000 [10] The Internet Society expects 120 millionhosts to be connected to the Internet by the end of the decade, up from 9.5million in 1996. [11] Investment bankers at Morgan Stanley project that thenumber of Web users will jump from 9 million in 1995 to more than 150 millionbyr 2000. [12]
