History of Browsers

The first web browser was invented in 1990 by Sir Tim Berners-Lee.
The first commonly available web browser with a graphical user interface was Erwise. The development of Erwise was initiated by Robert Cailliau.

In 1993, browser software was further innovated by Marc Andreessen with the release of Mosaic, "the world's first popular browser.
Microsoft responded with its Internet Explorer in 1995.
Opera debuted in 1996; it has never achieved widespread use.
In 1998, Netscape launched what was to become the Mozilla Foundation in an attempt to produce a competitive browser using the open source software model. That browser would eventually evolve into Firefox, which developed a respectable following while still in the beta stage of development.
Apple's Safari had its first beta release in January 2003; as of April 2011.
The most recent major entrant to the browser market is Chrome, first released in September 2008.

This process begins when the user inputs a Uniform Resource Locator (URL), for example http://en.wikipedia.org/, into the browser. The prefix of the URL, the Uniform Resource Identifier or URI, determines how the URL will be interpreted. The most commonly used kind of URI starts with http: and identifies a resource to be retrieved over the Hypertext Transfer Protocol (HTTP). Many browsers also support a variety of other prefixes, such as https: for HTTPSftp: for the File Transfer Protocol, and file: for local files. Prefixes that the web browser cannot directly handle are often handed off to another application entirely. For example, mailto: URIs are usually passed to the user's default e-mail application, and news: URIs are passed to the user's default newsgroup reader.
