History of the World Wide Web
The World Wide Web ("WWW", "W3" or simply "the Web") is a global information medium that users can access via computers connected to the Internet. The term is often used as a synonym for the Internet, but the Web is a service that operates over the Internet, just as email and Usenet do. The history of the Internet and the history of hypertext date back significantly further than that of the World Wide Web.
Tim Berners-Lee invented the World Wide Web while working at CERN in 1989. He proposed a "universal linked information system" using several concepts and technologies, the most fundamental of which was the connections that existed between information. He developed the first web server, the first web browser, and a document formatting protocol, called Hypertext Markup Language (HTML). After publishing the markup language in 1991, and releasing the browser source code for public use in 1993, many other web browsers were soon developed, with Marc Andreessen's Mosaic (later Netscape Navigator) being particularly easy to use and install, and often credited with sparking the Internet boom of the 1990s. It was a graphical browser which ran on several popular office and home computers, bringing multimedia content to non-technical users by including images and text on the same page.
Websites for use by the general public began to emerge in 1993–94. This spurred competition in server and browser software, highlighted in the Browser wars which was initially dominated by Netscape Navigator and Internet Explorer. Following the complete removal of commercial restrictions on Internet use by 1995, commercialization of the Web amidst macroeconomic factors led to the dot-com boom and bust in the late 1990s and early 2000s.
The features of HTML evolved over time, leading to HTML version 2 in 1995, HTML3 and HTML4 in 1997, and HTML5 in 2014. The language was extended with advanced formatting in Cascading Style Sheets (CSS) and with programming capability by JavaScript. AJAX programming delivered dynamic content to users, which sparked a new era in Web design, styled Web 2.0. The use of social media, becoming commonplace in the 2010s, allowed users to compose multimedia content without programming skills, making the Web ubiquitous in everyday life.
The underlying concept of hypertext as a user interface paradigm originated in projects in the 1960s, from research such as the Hypertext Editing System (HES) by Andries van Dam at Brown University, IBM Generalized Markup Language, Ted Nelson's Project Xanadu, and Douglas Engelbart's oN-Line System (NLS).[page needed][non-primary source needed] Both Nelson and Engelbart were in turn inspired by Vannevar Bush's microfilm-based memex, which was described in the 1945 essay "As We May Think".[title missing] Other precursors were FRESS and Intermedia. Paul Otlet's project Mundaneum has also been named as an early 20th-century precursor of the Web.
In 1980, Tim Berners-Lee, at the European Organization for Nuclear Research (CERN) in Switzerland, built ENQUIRE, as a personal database of people and software models, but also as a way to experiment with hypertext; each new page of information in ENQUIRE had to be linked to another page. When Berners-Lee built ENQUIRE, the ideas developed by Bush, Engelbart, and Nelson did not influence his work, since he was not aware of them. However, as Berners-Lee began to refine his ideas, the work of these predecessors would later help to confirm the legitimacy of his concept.
During the 1980s, many packet-switched data networks emerged based on various communication protocols (see Protocol Wars). One of these standards was the Internet protocol suite, which is often referred to as TCP/IP. As the Internet grew through the 1980s, many people realized the increasing need to be able to find and organize files and use information. By 1985, the Domain Name System (upon which the Uniform Resource Locator is built) came into being.[better source needed][failed verification] Many small, self-contained hypertext systems were created, such as Apple Computer's HyperCard (1987).
Berners-Lee's contract in 1980 was from June to December, but in 1984 he returned to CERN in a permanent role, and considered its problems of information management: physicists from around the world needed to share data, yet they lacked common machines and any shared presentation software. Shortly after Berners-Lee's return to CERN, TCP/IP protocols were installed on Unix machines at the institution, turning it into the largest Internet site in Europe. In 1988, the first direct IP connection between Europe and North America was established and Berners-Lee began to openly discuss the possibility of a web-like system at CERN. He was inspired by a book, Enquire Within upon Everything. Many online services existed before the creation of the World Wide Web, such as CompuServe, Usenet, Internet Relay Chat, Telnet and bulletin board systems. Before the internet, UUCP was used for online services such as e-mail, and BITNET was also another popular network.
