, 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 (thought up by sales representative Greg Sands) and named its flagship web browser Netscape Navigator.

Netscape announced in its first press release (October 13, 1994) 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 March 6, 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 cryptographer 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 (and later CDs) in stores along with a period of phone support. 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

s 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

 (in version 2.0). 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

, 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 market.

The fall of Netscape

With the success of Netscape showing the importance of the web (more and more people were using the Internet due in part to the ease of using Netscape) Microsoft then saw a new profitable market they could take over. Anti-Microsoft banter and talk of Netscape Constellation eliminating the operating system further forced Microsoft's hand. 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. (University of Illinois). Using this basic code, Microsoft created Internet Explorer

. Moreover, Netscape Communicator's browser interface design appeared dated in comparison to Internet Explorer and interface changes in Microsoft and Apple's operating systems.

However, these web browsers took years to yield results. Meanwhile, America Online had bought Netscape, and released Netscape Navigator 6 from a pre-beta-quality form of the Mozilla codebase. This did nothing to win back users, who continued to migrate to Internet Explorer. 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.

, 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 (thought up by sales representative Greg Sands) and named its flagship web browser Netscape Navigator.

Netscape announced in its first press release (October 13, 1994) 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.AOL.com - Netscape

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.AOL.com - Netscape

The reversal was complete with the availability of version 1.1 beta on March 6, 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 cryptographer 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 (and later CDs) in stores along with a period of phone support. 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

s 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

, 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 market.

The fall of Netscape

With the success of Netscape showing the importance of the web (more and more people were using the Internet due in part to the ease of using Netscape) Microsoft then saw a new profitable market they could take over. Anti-Microsoft banter and talk of Netscape Constellation eliminating the operating system further forced Microsoft's hand. 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. (University of Illinois). Using this basic code, Microsoft created Internet Explorer

However, these web browsers took years to yield results. Meanwhile, America Online had bought Netscape, and released Netscape Navigator 6 from a pre-beta-quality form of the Mozilla codebase.

On 28 December 2007, the Netscape developers announced that AOL had canceled development of Netscape Navigator, leaving it unsupported as of 1 March 2008.BBC News Article retrieved 29th February 2008 Despite this, archived and unsupported versions of the browser remain available for download.

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.AOL.com - Netscape

The reversal was complete with the availability of version 1.1 beta on March 6, 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 cryptographer 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 (and later CDs) in stores along with a period of phone support. Email support was initially free, and remained so for a year or two until the volume of support requests grew too high.

s 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

, 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 market.

The fall of Netscape

With the success of Netscape showing the importance of the web (more and more people were using the Internet due in part to the ease of using Netscape) Microsoft then saw a new profitable market they could take over. Anti-Microsoft banter and talk of Netscape Constellation eliminating the operating system further forced Microsoft's hand. 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. (University of Illinois). Using this basic code, Microsoft created Internet Explorer

. Moreover, Netscape Communicator's browser interface design appeared dated in comparison to Internet Explorer and interface changes in Microsoft and Apple's operating systems.

However, these web browsers took years to yield results. Meanwhile, America Online had bought Netscape, and released Netscape Navigator 6 from a pre-beta-quality form of the Mozilla codebase. This did nothing to win back users, who continued to migrate to Internet Explorer. On 28 December 2007, the Netscape developers announced that AOL had canceled development of Netscape Navigator, leaving it unsupported as of 1 March 2008.BBC News Article retrieved 29th February 2008 Despite this, archived and unsupported versions of the browser remain available for download.

Criticism

Netscape has been criticized for not meeting then-current web standards, often lagging behind or supporting them very poorly or even incorrectly. This criticism wasn't very loud during the days of its popularity as web designers then often simply developed for Netscape Navigator, but came to be an increasing annoyance to web designers who wish to provide backward compatibility
