Back in the year 1989, Tim Berners-Lee ( at CERN ) wrote a proposal based on ENQUIRE, to write an information system. This system was targeted to meet the need of Physists at CERN to share information with each other. Web is a «Side Effect» of the 40 years of Particle Physics Experiments.
On August 6, 1991, the first website was built at CERN. On the same date Tim also posted a short summary of the World Wide Web project on the alt.hypertext newsgroup. This date also marked the debut of the Web as a publicly available service on the Internet.
Mid 1990s was the era when Web Development had started to evolve. This was the era of evolution of Web Browsers and Web Servers. The very first web browser WorldWideWeb ( which was also on editor ) was created by Tim. It was actually Mosaic web browser, developed at NCSA and released on 23rd January 1993, ( released for Unix, Windows 3.0, Amiga 2.0 ), which made the web even more popular. As the popularity increased, the demand for processing power from the web-server’s end also increased. A suite of Mozilla projects ( including Firefox web browser ) are among descendendts of Mosaic web browser itself.
Marc Andreessen, the leader of the team that developed Mosaic, left NCSA and, with James H. Clark, one of the founders of Silicon Graphics, Inc. (SGI), and four other former students and staff of the University of Illinois, started Mosaic Communications Corporation. Mosaic Communications eventually became Netscape Communications Corporation, producing Netscape Navigator. Wikipedia entry
Until 1995, it was only HTML that was used to present content on the web. The late mid-1990s saw commercialization of WWW. Which resulted in emerging technologies like Java Applets in 1995, and Macromedia Flash i 1996. The later technology changed the way content would be delivered on the web. A whole new set of primitives were available to the developers now with availability of Flash.
And now the latest buzzword on over the web is HTML5. Its important to note that HTML5 is still under development and there hasn’t been any final release of its specification. This is the technology that made Steve Jobs ponder over and give his «Thoughts on Flash». Of his thoughts, he says that Flash is is a memory-hog, it is prorietary and a closed-specification and is too difficult to deal with, hence it won’t be supported on Apple mobile devices.
What’s new with HTML5 you may ask? In simple terms it is just a bunch of tags and features namely: video, audio, canvas, local storage, web sql etc. Its only when you apply creativity, that you realize full potential of HTML5.
Recently, Adobe released an experimental project named Wallaby, which converts Flash files into equivalent HTML5 content.

The very first web server was the CERN HTTPd. However it was NCSA httpd that became most popular during its time. When its main developer, Robert McCool left NCSA in 1994, development of NCSA httpd stalled. It was bad thing to happen as there were a lot of people who depended on this web server. It was then that a small group webmasters got in contact via email and, took the NCSA httpd code as a base and started a public domain project called Apache httpd.
It is not practical to design and develop every new Web application from the ground up. We would have to keep building the same functional components that accept and interpret user requests, authenticate and authorize the requestors, access and transform requested data, and construct and transmit final responses. Many of these components would be identical across different applications. Web servers provide application developers with well-defined endpoints—the acceptance of requests and transmission of responses. Some servers also lay the simple groundwork for building and deploying Web applications. In practice, such groundwork is not enough: what is needed is the additional infrastructure to facilitate Web application development and deployment.
What does a Web Application framework do? It primarily allows separation of content from presentation.
N-Tier architecture: commonly used as 3-tier
We have come a long way sine 1991, when the first HTML page was created. Now we have loads of technologies, frameworks, languages, and mindsets. WWW is impacting the world every day, in the ways no one had ever imagined earlier.
Today I can get to know about the latest happenings in Japan, at the blink of an eye ( just refresh news.google.com ). All this has been made possible by the World Wide Web.
Thats all folks :)
