According to Netcraft, a company tracking data on the internet, the number of websites went from one million (April 1997) to 10 million (February 2000), 20 million (September 2000), 30 million (July 2001), 40 million (April 2003), 50 million (May 2004), 60 million (March 2005), 70 million (August 2005), 80 million (April 2006), 90 million (August 2006) and 100 million (November 2006), with a growing number of personal websites and blogs. The term “web 2.0” was invented in 2004 by Tim O’Reilly, a publisher of computer books, as a title for a series of conferences he was organizing. The web 2.0 may begin to answer Tim Berners-Lee’s dream as a web based on community and sharing, with many collaborative projects across borders and languages. Fifteen years after the invention the web, Wired stated in its August 2005 issue that less than half of the web was commercial, with the other half being run by passion. As for the internet, according to the French daily Le Monde dated 19 August 2005, its three powers -- ubiquity, variety and interactivity -- made its potential use quasi infinite. Robert Beard, a language teacher at Bucknell University, Pennsylvania, and the founder of A Web of Online Dictionaries in 1995, wrote as early as September 1998: "The web will be an encyclopedia of the world by the world for the world. There will be no information or knowledge that anyone needs that will not be available. The major hindrance to international and interpersonal understanding, personal and institutional enhancement, will be removed. It would take a wilder imagination than mine to predict the effect of this development on the nature of humankind." 1991 > FROM ASCII TO UNICODE [Summary] Used since the beginning of computing, ASCII (American Standard Code for Information Interchange) is a 7-bit coded character set for information interchange in English. It was published in 1963 by ANSI (American National Standards Institute). With the internet spreading worldwide, to communicate in English (and Latin) was not enough anymore. The accented characters of several European languages and characters of some other languages were taken into account from 1986 onwards with 8-bit variants of ASCII, also called extended ASCII, that provided sets of 256 characters. But problems were not over until the publication of Unicode in January 1991 as a new universal encoding system. Unicode provided "a unique number for every character, no matter what the platform, no matter what the program, no matter what the language", and could handle 65,000 characters or ideograms. *** With the internet spreading worldwide, the use of ASCII and extended ASCII was not enough anymore, thus the need to take into account all languages with Unicode, whose first version was published in January 1991.
