<P> By 1990, ARPANET's goals had been fulfilled and new networking technologies exceeded the original scope and the project came to a close . New network service providers including PSINet, Alternet, CERFNet, ANS CO + RE, and many others were offering network access to commercial customers . NSFNET was no longer the de facto backbone and exchange point of the Internet . The Commercial Internet eXchange (CIX), Metropolitan Area Exchanges (MAEs), and later Network Access Points (NAPs) were becoming the primary interconnections between many networks . The final restrictions on carrying commercial traffic ended on April 30, 1995 when the National Science Foundation ended its sponsorship of the NSFNET Backbone Service and the service ended . NSF provided initial support for the NAPs and interim support to help the regional research and education networks transition to commercial ISPs . NSF also sponsored the very high speed Backbone Network Service (vBNS) which continued to provide support for the supercomputing centers and research and education in the United States . </P> <P> The World Wide Web (sometimes abbreviated "www" or "W3") is an information space where documents and other web resources are identified by URIs, interlinked by hypertext links, and can be accessed via the Internet using a web browser and (more recently) web - based applications . It has become known simply as "the Web". As of the 2010s, the World Wide Web is the primary tool billions use to interact on the Internet, and it has changed people's lives immeasurably . </P> <P> Precursors to the web browser emerged in the form of hyperlinked applications during the mid and late 1980s (the bare concept of hyperlinking had by then existed for some decades). Following these, Tim Berners - Lee is credited with inventing the World Wide Web in 1989 and 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 Firefox, Internet Explorer, Google Chrome, Opera and Safari . </P> <P> A boost in web users 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 Windows' Internet Explorer . Commercial use restrictions were lifted in 1995 . The online service America Online (AOL) offered their users a connection to the Internet via their own internal browser . </P>
