A short info about netscape navigator

Netscape Navigator was a web browser, the first commercial product of the company Netscape Communications created by Marc Andreessen (one of the authors of Mosaic) when there was in the National Center for Supercomputing Applications (NCSA: National Center of Applications for Supercomputers) of the University of Illinois in Urbana-Champaign. Netscape was the first commercial navigator.


Netscape beginnings.

Netscape announced on October 13, 1994 that there would throw an available mariner of free form for all his not commercial users, and that the versions thread 1.0 and thread 1.1 will be able to disburden in November, 1994 and March, 1995. The final version 1.0 was available in December, 1994. Netscape made free the availability of his software because it had in his policies the notion of which the software for Internet did not have to have cost In 1997, the Netscape Navigator 2.0 was the mariner first in including a language of script in the web pages, when JavaScript introduced in his version 2. Originally, scarcely it was serving for something more that to validate forms, but rapidly it was expanding. On he having be added by aptitudes to read and send messages, so much e-mail as So much e-mail as of netnews, there appears the version Communicator. The publisher of pages Netscape Composer got in the ' version 3, gives place to the name Gold for the distributions that include it. It was very criticized by the supporters of the standards in Internet for introducing in the HTML great quantity of proprietary extensions (or netscapismos), that is to say, created by his authors, without respecting the recommendations of the Web World Wide Consortium, which was damaging the compatibility of the pages between mariners and to the aim to come to the semantic web. Between the proprietary extensions introduced by Netscape the frames and the layers stand out. The version 4 introduced the leaves of style in waterfall (CSS) and dynamic HTML across JavaScript and a proprietary extension .Unfortunately, this version was infected of bugs, and his implementation of the dynamic HTML was lower than that of the Internet Explorer 4. This, joined the Internet integration Explorer in Microsoft Windows, led to the so called " navigators' war " between both companies, which introduced abundant own and incompatible extensions between yes to HTML and JavaScript. This forced many people to create two versions of his pages, one for every mariner. The result of this 'war' was the victory of the Internet Explorer, which obtained a quota of 98 % in the mariners' use, and Netscape Navigator's later disappearance. This victory owed to itself, fundamentally, to the Internet incorporation Explorer as one more component of Microsoft Windows, which was doing that the immense majority of the users they had it though they had not installed it as such, and were not bothering to look for other one. The version 5 was in development for years, but the difficulty of modifying the source code to allow the modification of the pages after his load joined the progressive economic losses of the company, did that it was never going out to the market. This way, Netscape lost the war of the mariners in favor of Internet Explorer, which already was going for the version 5. Finally, his code was liberated, in order that the developers' community of free software could help to finish it. This gave place to the Foundation Mozilla, which rewrote almost the whole code, creating the mariner Mozilla Application Suite. The versions 6 and 7 were based on the code of the project Mozilla. At present, to the credit. At present, when Netscape has left the development of his navigator, it is possible to consider Mozilla Navigator to be his successor.

Liberation of the project

In March, 1997, Netscape liberated the majority of Netscape Communicator's code and put it under the free license. The project was called Mozilla. It estimated that to complete the source code (the elements with copyright owner had to be eliminated) in a mariner's new version, it might go one year, and of this form was decided that the next version of the mariner Netscape, version 5.0, would be based on this one. Netscape assigned his engineers of development of his mariner in order that they were helping in the project.

After one year, it was evident that Mozilla's development was not so fast, for what Netscape re-assigned any of his engineers to the version Netscape Communicator 4.5. This had the effect of forwarding part of the efforts in a dead line, while the mariner of Microsoft, Internet Explorer 5.0, it was still developing. The engineers of Mozilla decided to throw Communicator's code and to begin from zero. The Mozilla's first public version, two years later, did not have acceptance great since many computers of average level were too slow to execute a mariner who was using his user's own graphical interface and customizable with the Extensible language Markup Language (XML).

There was avoided the version 5 because Microsoft Internet Explorer 5.0 was available from it was doing one year and a half. There were plans to liberate a based version 5.0 on the code 4.x, but this idea was rejected and all the resources were in use for working in Mozilla Netscape's version 6.0, in what some employees of Netscape still consider one of the major mistakes in the history of the company.

With enough advertising, the company AOL as new owner of Netscape, liberated Netscape on November 6 14, 2000 based on the code of Mozilla's previous version. The product was a colossal disappointment: it was enormous, slow, unstable and visually not attraction (for the great majority). Nothing of this was a surprise, since Mozilla's core was not near being available as new version for yes same, and it was very unstable.

Netscape 6.1 and Netscape 6.2, liberated in 2001, solved the problems of stability, but they were too big and slow, and 6 did not improve Netscape's bad reputation, by what they were ignored of form generalized by the market.

In 2002, AOL liberated Netscape 7: based on Mozilla's core 1.0, the the stablest and notably more rapid, took several extras as the AOL integrated Instant Messenger, ICQ and Radio@Netscape. The market answered that it was essentially Mozilla's re-stiff version with a series of integrated tools that they were allowing to accede to the services managed by AOL, by what it was ignored again. The competition between the alternatives non-Microsoft you mature and competent as the mariner Opera and Mozilla's distribution was another decisive factor. The version Netscape 7.1 (based on Mozilla 1.4) was ignored also.

In the platform Windows, the mariner Netscape has been irrelevant for enough years. Still there are some users of recent versions, but the majority they are persons who are not arranged, or cannot, change mariner from the versions 4.x, since normally the most recent mariners need machines with major power of calculation for an acceptable performance. In other platforms, which do not have the possibility of installing Internet Explorer, as GNU/Linux, Netscape it supported his position as dominant mariner during more time. Only in the last years, the appearance of other alternatives like Mozilla and Konqueror they have supposed an increase of the competition.


AOL announced on July 14, 2003 that it was going to withdraw to the whole personnel of development that was employed at Netscape de Mozilla's version. Cocktail with the agreement between Microsoft and AOL to use the Internet version Explorer in the future versions of software, marked Netscape's end as entity and relegated it to little more than one historical note. The name of brand Netscape like Internet service provider with telephonic call.
