History of the World Wide Web Timeline

Following the introduction of the Web, several media formats based on discrete cosine transform (DCT) were introduced for practical media distribution and streaming over the Web, including the MPEG video format in 1991.

A DCT variation, the modified discrete cosine transform (MDCT) algorithm, led to the development of MP3, introduced in 1991, which became the first popular audio format on the Web.

Gopher was a document browsing system for the Internet, released in 1991 by the University of Minnesota. It competed with the early Web before licensing restrictions led to its decline.

The JPEG image format, based on discrete cosine transform compression, was introduced in 1992 as one of several media formats enabling practical image distribution over the Web.

A shortcoming of the first browser was discussed in January 1992 and alleviated by the release of ViolaWWW, created by Pei-Yuan Wei, followed by Erwise from Helsinki University of Technology students and MidasWWW by Tony Johnson at SLAC.

The National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana–Champaign established a website in November 1992, setting the stage for the Mosaic browser developed there.

Students at the University of Kansas adapted an existing text-only hypertext browser, Lynx, to access the web in 1993, providing another popular way to browse early websites.

Websites for use by the general public began to emerge in 1993–94, expanding the Web beyond academic and scientific communities. By October 1993 there were over five hundred servers online, up from fifty in January 1993.

After Marc Andreessen saw ViolaWWW in late 1992, he began work on Mosaic with Eric Bina at UIUC, funded by the High-Performance Computing and Communications Initiative initiated by Senator Al Gore. A Unix version was released in February 1993; Mac and Windows versions followed in August 1993. Historians agree Mosaic was a turning point for the Web.

Cello, a web browser for Microsoft Windows, was released in June 1993, bringing web access to users of the increasingly popular Windows platform.

By 1994, Marc Andreessen's Netscape Navigator superseded Mosaic in popularity, holding the leading position among web browsers for some time.

In January 1994, Yahoo! was founded by Jerry Yang and David Filo, then students at Stanford University, becoming one of the most popular directories and portals of the early Web.

After 1993 the World Wide Web saw many advances to indexing and ease of access through search engines, which often neglected Gopher. By the middle of 1994, the Web was outcompeting Gopher and other Internet browsing systems.

After graduating from UIUC, Marc Andreessen and Jim Clark, former CEO of Silicon Graphics, met and formed Mosaic Communications Corporation in April 1994 to develop the Mosaic Netscape browser commercially.

Bill Gates outlined Microsoft's strategy to dominate the Internet in his Tidal Wave memo in 1995, redirecting the company's focus toward the Web and setting up the browser wars.

Netscape followed up with Navigator 2 in 1995, introducing frames, Java applets and JavaScript, greatly expanding what web pages could do.

Following the complete removal of commercial restrictions on Internet use by 1995 when NSFNET was shut down, commercialization of the Web amidst macroeconomic factors led to the dot-com boom and bust in the late 1990s and early 2000s.

Online shopping began to emerge with the launch of Amazon's shopping site by Jeff Bezos in 1995 and eBay by Pierre Omidyar the same year, pioneering e-commerce on the Web.

In 1998, Netscape made Navigator open source and launched Mozilla. That same year AOL bought Netscape, and IE captured the majority of the desktop browser market. AOL disbanded Netscape in 2003.

The World Wide Web Consortium (W3C) was founded by Tim Berners-Lee after he left CERN in September/October 1994 in order to create open standards for the Web. A second site was later founded at INRIA, and in 1996 a third continental site was created in Japan at Keio University.

The features of HTML evolved over time, leading to HTML version 2 in 1995, an early standardization of the markup language underlying the Web.

In 1995, Brian Behlendorf and Cliff Skolnick created a mailing list to coordinate efforts to fix bugs and make improvements to HTTPd, leading to the Apache web server. Following its success, the Apache Software Foundation was founded in 1999.

Frustrated by inconsistent browser implementations despite the W3C's HTML 4 standard of 1997 (which included CSS), web designers formed the Web Standards Project (WaSP) in 1998 with the goal of cajoling compliance with standards.

Microsoft added a little-noticed feature called XMLHttpRequest to Internet Explorer in 1999, which enabled a web page to communicate with the server while remaining visible, laying the groundwork for Ajax applications.

The term Web 2.0 was coined in 1999 by Darcy DiNucci and later popularized in 2004 at the Web 2.0 Conference, describing a new media-rich model featuring user-generated and user-edited websites. Web 1.0 refers retroactively to the Web's first stage, roughly 1989 to 2004.

Developers at Oddpost used XMLHttpRequest in 2002 to create the first Ajax application, a webmail client that performed as well as a desktop application, demonstrating the power of dynamic web interfaces.

In 2004, representatives from Mozilla, Opera, and Apple formed the Web Hypertext Application Technology Working Group (WHATWG), dedicated to improving HTML while maintaining backward compatibility, opposing the W3C's XHTML direction.

Apple introduced the first smartphone in 2007 with a full-featured browser, transforming how people accessed the Web. Other companies followed suit, and in 2011 smartphone sales overtook PCs.

By 2007, the W3C conceded and announced they were restarting work on HTML, and in 2009 they officially abandoned XHTML, aligning with the WHATWG's approach.

Google released their Chrome browser in 2008 with the first JIT JavaScript engine, V8, dramatically improving JavaScript performance and reshaping the browser landscape.

Ryan Dahl used Chromium's V8 engine in 2009 to power Node.js, an event-driven runtime system that allowed JavaScript code to be used on servers as well as browsers.

Acer and Samsung began selling Chromebooks, cheap laptops running ChromeOS capable of running web apps, in 2011. The same year, Mozilla announced Web APIs to allow webapps to access hardware features such as audio, camera or GPS.

Mozilla released a mobile OS designed to run web apps in 2012, but discontinued it in 2015, an ambitious attempt to make the Web itself the mobile application platform.

The features of HTML evolved over time, culminating in HTML5 in 2014, a major revision supporting multimedia, graphics, and rich applications natively in the browser.

Google announced specifications for Accelerated Mobile Pages (AMP) and progressive web applications (PWA) in 2015, aiming to make web experiences faster and more app-like on mobile devices.

Since 2016, most visitors access websites with mobile devices, which led to the widespread adoption of responsive web design so pages adapt to screens of all sizes.

In 2019, the W3C ceded control of the HTML specification, now called the HTML Living Standard, to WHATWG, unifying the governance of the core web markup language.

Microsoft rewrote their Edge browser in 2021 to use Chromium as its code base in order to be more compatible with Chrome, consolidating the dominance of Chromium-based browsers.
