Netscape Navigator was a proprietary web browser.
It was the flagship product of the Netscape Communications Corp and was the dominant web
browser in terms of usage share in the 1990s, but by 2002 its usage had almost disappeared.
This was primarily due to the increased usage of Microsoft's Internet Explorer web browser
software, and partly because the Netscape Corporation did not sustain Netscape Navigator's
technical innovation after the late 1990s.
The business demise of Netscape was a central premise of Microsoft's antitrust trial, wherein
the Court ruled that Microsoft Corporation's bundling of Internet Explorer with the Windows
operating system was a monopolistic and illegal business practice.
The decision came too late for Netscape however, as Internet Explorer had by then become the
dominant web browser in Windows.
The Netscape Navigator web browser was succeeded by Netscape Communicator.
Netscape Communicator's 4.x source code was the base for the Netscape-developed Mozilla
Application Suite, which was later renamed SeaMonkey.
Netscape's Mozilla Suite also served as the base for a browser-only spinoff called Mozilla
Firefox and Netscape versions 6 through 9.
AOL stopped development of Netscape Navigator on 28 December 2007, but continued supporting
the web browser with security updates until 1 March 2008.
AOL allows downloading of archived versions of the Netscape Navigator web browser family.
AOL maintains the Netscape website as an Internet portal.
History and development Origin
Netscape Navigator was based on the Mosaic web browser, which was co-written by Marc
Andreessen, a part-time employee of the National Center for Supercomputing Applications and
a student at the University of Illinois.
After Andreessen graduated in 1993, he moved to California and there met Jim Clark, the
recently departed founder of Silicon Graphics.
Clark believed that the Mosaic browser had great commercial possibilities and provided
the seed money.
Soon Mosaic Communications Corporation was in business in Mountain View, California,
with Andreessen as a vice-president.
Since the University of Illinois was unhappy with the company's use of the Mosaic name,
the company changed its name to Netscape Communications and named its flagship web browser Netscape
Navigator.
Netscape announced in its first press release that it would make Navigator available without
charge to all non-commercial users, and beta versions of version 1.0 and 1.1 were indeed
freely downloadable in November 1994 and March 1995, with the full version 1.0 available
in December 1994.
Netscape's initial corporate policy regarding Navigator is interesting, as it claimed that
it would make Navigator freely available for non-commercial use in accordance with the
notion that Internet software should be distributed for free.
However, within 2 months of that press release, Netscape apparently reversed its policy on
who could freely obtain and use version 1.0 by only mentioning that educational and non-profit
institutions could use version 1.0 at no charge.
The reversal was complete with the availability of version 1.1 beta on 6 March 1995, in which
a press release states that the final 1.1 release would be available at no cost only
for academic and non-profit organizational use.
Gone was the notion expressed in the first press release that Navigator would be freely
available in the spirit of Internet software.
Some security experts and cryptographers found out that all released Netscape versions had
major security problems with crashing the browser with long URLs and 40 bits encryption
keys.
The first few releases of the product were made available in “commercial” and “evaluation”
versions; for example, version “1.0” and version “1.0N”.
The “N” evaluation versions were completely identical to the commercial versions; the
letter was there to remind people to pay for the browser once they felt they had tried
it long enough and were satisfied with it.
This distinction was formally dropped within a year of the initial release, and the full
version of the browser continued to be made available for free online, with boxed versions
available on floppy disks in stores along with a period of phone support.
During this era, "Internet Starter Kit" books were popular, and usually included a floppy
disk or CD containing internet software, and this was a popular means of obtaining Netscape's
and other browsers.
Email support was initially free, and remained so for a year or two until the volume of support
requests grew too high.
During development, the Netscape browser was known by the code name Mozilla, which became
the name of a Godzilla-like cartoon dragon mascot used prominently on the company's web
site.
The Mozilla name was also used as the User-Agent in HTTP requests by the browser.
Other web browsers claimed to be compatible with Netscape's extensions to HTML, and therefore
used the same name in their User-Agent identifiers so that web servers would send them the same
pages as were sent to Netscape browsers.
Mozilla is now a generic name for matters related to the open source successor to Netscape
Communicator.
The rise of Netscape
When the consumer Internet revolution arrived in the mid-to-late 1990s, Netscape was well-positioned
to take advantage of it.
With a good mix of features and an attractive licensing scheme that allowed free use for
non-commercial purposes, the Netscape browser soon became the de facto standard, particularly
on the Windows platform.
Internet service providers and computer magazine publishers helped make Navigator readily available.
An important innovation that Netscape introduced in 1994 was the on-the-fly display of web
pages, where text and graphics appeared on the screen as the web page downloaded.
Earlier web browsers would not display a page until all graphics on it had been loaded over
the network connection; this often made a user stare at a blank page for as long as
several minutes.
With Netscape, people using dial-up connections could begin reading the text of a web page
within seconds of entering a web address, even before the rest of the text and graphics
had finished downloading.
This made the web much more tolerable to the average user.
Through the late 1990s, Netscape made sure that Navigator remained the technical leader
among web browsers.
Important new features included cookies, frames, proxy auto-config, and JavaScript.
Although those and other innovations eventually became open standards of the W3C and ECMA
and were emulated by other browsers, they were often viewed as controversial.
Netscape, according to critics, was more interested in bending the web to its own de facto "standards"
than it was in fixing bugs in its products.
Consumer rights advocates were particularly critical of cookies and of commercial web
sites using them to invade individual privacy.
In the marketplace, however, these concerns made little difference.
Netscape Navigator remained the market leader with more than 50% usage share.
The browser software was available for a wide range of operating systems, including Windows,
Macintosh, Linux, OS/2, and many versions of Unix including DEC, Sun Solaris, BSD/OS,
IRIX, AIX, and HP-UX, and looked and worked nearly identically on every one of them.
Netscape began to experiment with prototypes of a web-based system, known internally as
“Constellation”, which would allow a user to access and edit his or her files anywhere
across a network no matter what computer or operating system he or she happened to be
using.
Industry observers confidently forecast the dawn of a new era of connected computing.
The underlying operating system, it was believed, would become an unimportant consideration;
future applications would run within a web browser.
This was seen by Netscape as a clear opportunity to entrench Navigator at the heart of the
next generation of computing, and thus gain the opportunity to expand into all manner
of other software and service markets.
Decline
With the success of Netscape showing the importance of the web, Internet browsing began to be
seen as a potentially profitable market.
Following Netscape's lead, Microsoft started a campaign to enter the web browser software
market.
Like Netscape before them, Microsoft licensed the Mosaic source code from Spyglass, Inc..
Using this basic code, Microsoft created Internet Explorer.
The competition between Microsoft and Netscape dominated the Browser Wars.
Internet Explorer, Version 1.0 and IE, Version 2.0 were thought by many to be inferior and
primitive when compared to contemporary versions of Netscape Navigator.
With the release of IE version 3.0 Microsoft was able to catch up with Netscape competitively,
with IE Version 4.0 further improving in terms of market share.
IE 5.0 improved stability and took significant market share from Netscape Navigator for the
first time.
There were two versions of Netscape Navigator 3.0; the Standard Edition and the Gold Edition.
The latter consisted of the Navigator browser with e-mail, news readers, and a WYSIWYG web
page compositor; however these extra functions enlarged and slowed the software, rendering
it prone to crashing.
This Gold Edition was renamed Netscape Communicator starting with version 4.0; the name change
diluted its name-recognition and confused users.
Netscape CEO Jim Barksdale insisted on the name change because Communicator was a general-purpose
client application, which contained the Navigator browser.
The aging Netscape Communicator 4.x was slower than Internet Explorer 5.0.
Typical web pages had become heavily illustrated, often JavaScript-intensive, and encoded with
HTML features designed for specific purposes but now employed as global layout tools.
The Netscape browser, once a solid product, became crash-prone and buggy; for example,
some versions re-downloaded an entire web page to re-render it when the browser window
was re-sized, and the browser would usually crash when the page contained simple Cascading
Style Sheets.
Moreover, Netscape Communicator's browser interface design appeared dated in comparison
to Internet Explorer and interface changes in Microsoft and Apple's operating systems.
At decade's end, Netscape's web browser had lost dominance over the Windows platform,
and the August 1997 Microsoft financial agreement to invest one hundred and fifty million dollars
in Apple required that Apple make Internet Explorer the default web browser in new Mac
OS distributions.
The latest IE Mac release at that time was Internet Explorer version 3.0 for Macintosh,
but Internet Explorer 4 was released later that year.
Microsoft succeeded in having ISPs and PC vendors distribute Internet Explorer to their
customers instead of Netscape Navigator, mostly due to Microsoft using its leverage from Windows
OEM licenses, and partly aided by Microsoft's investment in making IE brandable, such that
a customized version of IE could be offered.
Also, web developers used proprietary, browser-specific extensions in web pages.
Both Microsoft and Netscape were found guilty of supporting this, having added many proprietary
HTML tags to their browsers, which forced users to choose between two competing and
almost incompatible web browsers.
In March 1998, Netscape released most of the development code base for Netscape Communicator
under an open source license.
Only pre-alpha versions of Netscape 5 were released before the open source community
decided to scrap the Netscape Navigator codebase entirely and build a new web browser around
the Gecko layout engine which Netscape had been developing but which had not yet incorporated.
The community-developed open source project was named Mozilla, Netscape Navigator's original
code name.
America Online bought Netscape; Netscape programmers took a pre-beta-quality form of the Mozilla
codebase, gave it a new GUI, and released it as Netscape 6.
This did nothing to win back users, who continued to migrate to Internet Explorer.
After the release of Netscape 7 and a long public beta test, Mozilla 1.0 was released
on 5 June 2002.
The same code-base, notably the Gecko layout engine, became the basis of independent applications,
including Firefox and Thunderbird.
On 28 December 2007, the Netscape developers announced that AOL had canceled development
of Netscape Navigator, leaving it unsupported as of 1 March 2008.
Despite this, archived and unsupported versions of the browser remain available for download.
Firefox would go on to win back market share from Internet Explorer in the next round of
the browser wars.
Legacy Netscape's contributions to the web include
JavaScript, which was submitted as a new standard to Ecma International.
The resultant ECMAScript specification allowed JavaScript support by multiple web browsers
and its use as a cross-browser scripting language, long after Netscape Navigator itself has dropped
in popularity.
Another example is the FRAME tag, that is widely supported today, and that has been
incorporated into official web standards such as the "HTML 4.01 Frameset" specification.
In a 2007 PC World column, the original Netscape Navigator was considered the "best tech product
of all time" due to its impact on the Internet.
