<P> A web browser is a software application for retrieving, presenting and traversing information resources on the World Wide Web . An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content . Hyperlinks present in resources enable users easily to navigate their browsers to related resources . A web browser can also be defined as an application software or program designed to enable users to access, retrieve and view documents and other resources on the Internet . </P> <P> Precursors to the web browser emerged in the form of hyperlinked applications during the mid and late 1980s, and following these, Tim Berners - Lee is credited with developing in 1990 both the first web server, and the first web browser, called WorldWideWeb (no spaces) and later renamed Nexus . Many others were soon developed, with Marc Andreessen's 1993 Mosaic (later Netscape), being particularly easy to use and install, and often credited with sparking the internet boom of the 1990s . Today, the major web browsers are Chrome, Safari, Internet Explorer, Firefox, and Edge . </P> <P> The explosion in popularity of the Web was triggered in September 1993 by NCSA Mosaic, a graphical browser which eventually ran on several popular office and home computers . This was the first web browser aiming to bring multimedia content to non-technical users, and therefore included images and text on the same page, unlike previous browser designs; its founder, Marc Andreessen, also established the company that in 1994, released Netscape Navigator, which resulted in one of the early browser wars, when it ended up in a competition for dominance (which it lost) with Microsoft's Internet Explorer (for Windows). </P>
