Since ¡¥the internet is a vast global interconnection of some 100,000 computer networks around the world all of which use a common set of technical protocols (called Transmission Control Protocol/Internet Protocols of TCP/IP) in routing data across those networks¡¦ (Pavilk. J, 1998, pp29), the ubiquity of personal computers can be considered as one of the reasons in explaining the rapid growth of the Internet. The first personal computer was available on the market on 9 September 1975 from IBM, which cost from US$8975 to US$19,975 accord

The development of the Mosaic in 1993, the first web browser, contribute the World Wide Web even more successful since it ¡¥provided a graphical user interface that let users simply click a mouse on images or words to select text, images, or sounds from the many databases available in the Internet¡¦ (Pavilk, J, 1998, pp. 38). The innovation of WWW and mosaic caused Internet grow dramatically to global network. According to Flew, T, after the birth of WWW and mosaic, the annual growth rate of hosted Internet jumped from 68.8% in 1994 and 188.5% in 1995, when the mosaic is widely available on personal computers.

However, as this new technology become more and more common in the society, the price of the personal computer become more affordable and reasonable to the public so that more and more people can pay for a personal computer. ¡¥By the mid-1990s, 35% of all US households had a computer; this represented about 10 million machines. By 1996, the figure had risen to about 22 million¡¦ (Dearnley, J & Feather, J, 2001, pp30). In another words, the personal computers popularisation greatly enlarges the network of Internet as more people have a computer, the fundamental needs for Internet, to get online. As Kitchin, R suggests, ¡¥with the increase in the number of personal computers, the potential number of users of the Internet has increased¡¦ (1998, pp. 38).

Other than the common protocol innovation, the invention of World Wide Web and Mosaic are the key for the booming of Internet as it greatly enhance the user-friendliness of internet. As Pavilk, J said, ¡¥perhaps the most important and fastest growing part of the internet is the World Wide Web¡¦ (1998, pp36). The development of World Wide Web allow
