Can You Download Mosaic Web Browser
Albert Phelps
The Mosaic browser was the first browser to introduce two features new to the browser world: allowing for pictures to be viewed directly on the page instead of needing to be downloaded and viewed separately, and using hyperlinks that could take a user directly to the new page instead of making a user manually type the address to the new page.
Technically Mosaic browser can still be downloaded and used, however it may not support much of today\u2019s Internet as protocols and website features have become more advanced than Mosaic\u2019s last upgrade in 1997.\n"}},"@type":"Question","name":"Who built Mosaic browser?","acceptedAnswer":"@type":"Answer","text":"Marc Andreessen and Eric Brina at the NCSA in the University of Illinois began developing the Mosaic browser in 1991, releasing the first official Mosaic browser in 1993.\n","@type":"Question","name":"Was Mosaic the first browser?","acceptedAnswer":"@type":"Answer","text":"Mosaic was not the first browser or even the first graphical browser, but it was the most user friendly browser at the time of its release.\n","@type":"Question","name":"How did Mosaic revolutionize web browsing?","acceptedAnswer":"@type":"Answer","text":"The Mosaic browser was the first browser to introduce two features new to the browser world: allowing for pictures to be viewed directly on the page instead of needing to be downloaded and viewed separately, and using hyperlinks that could take a user directly to the new page instead of making a user manually type the address to the new page.\n","@type":"Question","name":"When was Mosaic browser created?","acceptedAnswer":"@type":"Answer","text":"The Mosaic browser was first developed in 1991, and first officially released to the public in 1993.\n","@type":"Question","name":"Where was Mosaic developed?","acceptedAnswer":"@type":"Answer","text":"The Mosaic browser was developed in the National Center for Supercomputing Applications (NCSA) at the University of Illinois.\n"]} History Computer Staff, Author for History-Computer
NCSA Mosaic is a discontinued web browser, and one of the first to be widely available. It was instrumental in popularizing the World Wide Web and the general Internet by integrating multimedia such as text and graphics.[3][4][5] It was named for its support of multiple Internet protocols, such as Hypertext Transfer Protocol, File Transfer Protocol, Network News Transfer Protocol, and Gopher.[6] Its intuitive interface, reliability, personal computer support, and simple installation all contributed to its popularity within the web.[7] Mosaic is the first browser to display images inline with text instead of in a separate window.[8] It is often described as the first graphical web browser, though it was preceded by WorldWideWeb, the lesser-known Erwise,[9] and ViolaWWW.
In 1994, SCO released Global Access, a modified version of SCO's Open Desktop Unix, which became the first commercial product to incorporate Mosaic.[20] However, by 1998, the Mosaic user base had almost completely evaporated as users moved to other web browsers.
The licensing terms for NCSA Mosaic were generous for a proprietary software program. In general, non-commercial use was free of charge for all versions (with certain limitations). Additionally, the X Window System/Unix version publicly provided source code (source code for the other versions was available after agreements were signed). Despite persistent rumors to the contrary, however, Mosaic was never released as open source software during its brief reign as a major browser; there were always constraints on permissible uses without payment.
Mosaic is not the first web browser for Microsoft Windows; this is Thomas R. Bruce's little-known Cello. The Unix version of Mosaic was already famous before the Microsoft Windows, Amiga, and Mac versions were released. Other than displaying images embedded in the text (rather than in a separate window), Mosaic's original feature set is similar to the browsers on which it was modeled, such as ViolaWWW.[8] But Mosaic was the first browser written and supported by a team of full-time programmers, was reliable and easy enough for novices to install, and the inline graphics proved immensely appealing. Mosaic is said to have made the Internet accessible to the ordinary person.
Ultimately, web browsers such as Mosaic became the killer applications of the 1990s. Web browsers were the first to bring a graphical interface to search tools the Internet's burgeoning wealth of distributed information services. A mid-1994 guide lists Mosaic alongside the traditional, text-oriented information search tools of the time, Archie and Veronica, Gopher, and WAIS[33] but Mosaic quickly subsumed and displaced them all. Joseph Hardin, the director of the NCSA group within which Mosaic was developed, said downloads were up to 50,000 a month in mid-1994.[34]
In November 1992, there were twenty-six websites in the world[35] and each one attracted attention. In its release year of 1993, Mosaic had a What's New page, and about one new link was being added per day. This was a time when access to the Internet was expanding rapidly outside its previous domain of academia and large industrial research institutions. Yet it was the availability of Mosaic and Mosaic-derived graphical browsers themselves that drove the explosive growth of the Web to over 10,000 sites by August 1995 and millions by 1998.[36] Metcalfe expressed the pivotal role of Mosaic this way:
In the Web's first generation, Tim Berners-Lee launched the Uniform Resource Locator (URL), Hypertext Transfer Protocol (HTTP), and HTML standards with prototype Unix-based servers and browsers. A few people noticed that the Web might be better than Gopher.
VMS Mosaic, a version specifically targeting OpenVMS operating system, is one of the longest-lived efforts to maintain Mosaic. Using the VMS support already built-in in original version (Bjorn S. Nilsson ported Mosaic 1.2 to VMS in the summer of 1993),[45] developers incorporated a substantial part of the HTML engine from mMosaic, another defunct flavor of the browser.[46] As of the most recent version (4.2), released in 2007, VMS Mosaic supported HTML 4.0, OpenSSL, cookies, and various image formats including GIF, JPEG, PNG, BMP, TGA, TIFF and JPEG 2000 image formats.[47] The browser works on VAX, Alpha, and Itanium platforms.[48]
People had created Web browsers before. In fact Tim Berners-Lee, who first conceived of the World Wide Web while working at CERN, built a rudimentary one himself in 1990. Prior to anyone at NCSA putting down a line of code, researchers in Palo Alto and Berkeley and Helsinki were circulating their own versions, frequently with melodious names like Viola and Cello.
In 1993, the world's first freely available Web browser that allowed Web pages to include both graphics and text was developed by students and staff working at the NSF-supported National Center for Supercomputing Applications (NCSA) at the University of Illinois, Urbana-Champaign.
"Without Mosaic, Web browsers might not have happened or be what they are today," said Peter Freeman, NSF assistant director for CISE. "The growth of the Web and its impact on daily life shows the kind of dramatic payoff that NSF investments in computer science research can have for all areas of science and engineering, education and society as a whole."
But NCSA Mosaic was perhaps the most spectacular success. With a graphical browser, programmers began to post images, sound, video clips, and multi-font text within the Web's hypertext system. Less than 18 months after its introduction, Mosaic had become the Internet "browser of choice" for more than a million users and set off an exponential growth in the number of Web servers and surfers.
From January 1993, the National Center for Supercomputing Applications (NCSA) at the University of Illinois, provided pre-releases of its Mosaic browser for the Unix X Window System. The first official release was on 21 April 1993. Mosaic quickly gained popularity, becoming the browser of choice, with its user-friendly graphical interface and easy installation. Versions of Mosaic running on PC and Mac became available later that year.
News.com: "The original Internet Explorer team was just five or six people. By the time Silverberg and others decided to rewrite the browser almost completely for version 3.0, released in 1996, the team had grown to 100. By 1999, it was more than 1,000."
Life in the browser wars was a unique time period for me in my career. Spyglass was sort of like my first real job. When I joined the company in May 1992 the business was all about scientific data analysis tools. We had a little over $3M from Greylock and Venrock. It was a fun company, but data plotting isn't an explosive growth market. By 1994, everybody was starting to realize that.
Management made the decision to transition our business completely and pursue the market for web browsers. Tim Krauskopf, the founder and head of development, asked me to write a web browser. I started work on Spyglass Mosaic on April 5th, 1994. The demo for our first prospective customer was already on the calendar in May.
I ended up as the Project Lead for the browser team. Yes, we licensed the technology and trademarks from NCSA (at the University of Illinois), but we never used any of the code. We wrote our browser implementations completely from scratch, on Windows, MacOS, and Unix.
Netscape didn't even exist yet, but things happened fast. Just a few weeks after I started coding, Jim Clark rode into town and gathered a select group of programmers from NCSA. Mosaic Communications Corporation was born. It was interesting to note that certain people on the NCSA browser team were not invited to the special meeting. I can still remember hearing about how ticked off they were to be excluded. Champaign-Urbana is a very small town. :-)
We thought we had a nice head start on Netscape. We had a really top-notch team and we moved the rest of our developers over to browser work quickly. We were ready to compete with anybody. But Jim Clark was, after all, Jim Clark. His SGI-ness knew how to work the advantages of being in Silicon Valley. He provided his young company with lots of press coverage and very deep pockets.
