World Wide Web
The first web page may be lost, but Paul Jones of UNC-Chapel Hill in North Carolina announced in May 2013 that Berners-Lee gave him what he says is the oldest known web page during a 1991 visit to UNC. Jones stored it on a magneto-optical drive and on his NeXT computer. On 6 August 1991, Berners-Lee published a short summary of the World Wide Web project on the newsgroup "alt.hypertext". This date is sometimes confused with the public availability of the first web servers, which had occurred months earlier. As another example of such confusion, several news media reported that the first photo on the Web was published by Berners-Lee in 1992, an image of the CERN house band Les Horribles Cernettes taken by Silvano de Gennaro; Gennaro has disclaimed this story, writing that media were "totally distorting our words for the sake of cheap sensationalism."
History of the web browser
However, the explosion in popularity of the Web was triggered by NCSA Mosaic which was a graphical browser running originally on Unix and soon ported to the Amiga and VMS platforms, and later the Apple Macintosh and Microsoft Windows platforms. Version 1.0 was released in September 1993, and was dubbed the killer application of the Internet. It was the first web browser to display images inline with the document's text. Prior browsers would display an icon that, when clicked, would download and open the graphic file in a helper application. This was an intentional design decision on both parts, as the graphics support in early browsers was intended for displaying charts and graphs associated with technical papers while the user scrolled to read the text, while Mosaic was trying to bring multimedia content to non-technical users. Mosaic and browsers derived from it had a user option to automatically display images inline or to show an icon for opening in external programs. Marc Andreessen, who was the leader of the Mosaic team at NCSA, quit to form a company that would later be known as Netscape Communications Corporation. Netscape released its flagship Navigator product in October 1994, and it took off the next year.
