: What was the first web browser? |
Tim Berners-Lee who invented the World Wide Web in
1989 and first deployed a working system in 1990,
did so by writing a web browser for the NeXTStep operating
system. The original "WorldWideWeb" browser
program had a graphical user interface and so on and
is definitely recognizable to most people as a web
browser. However, WorldWideWeb did not support graphics
embedded in pages when it was first released. You
can learn more about the original "WorldWideWeb"
browser from Tim Berners-Lee himself.

The first web browser to become truly popular and
capture the imagination of the public was NCSA Mosaic.
Developed by Marc Andreessen, Jamie Zawinski and
others who later went on to create the Netscape
browser, NCSA Mosaic was the first to be available
for Microsoft Windows, the Macintosh, and the Unix
X Window System, which made it possible to bring
the web to the average user. The first version appeared
in March 1993. The "inline images," such
as the boutell.com logo at the top of this page,
that are an integral part of almost every web page
today were introduced by NCSA Mosaic 2.0, in January
of 1994. Mosaic 2.0 also introduced forms.
Netscape is the browser that introduced most all
of the remaining major features that define a web
browser as we know it. The first version of Netscape
appeared in October 1994 under the code name "Mozilla."
Netscape 1.0's early beta versions introduced the
"progressive rendering" of pages and images,
meaning that the page begins to appear and the text
can be read even before all of the text and/or images
have been completely downloaded. Version 1.1, in
March 1995, introduced HTML tables, which are now
used in the vast majority of web pages to provide
page layout. Version 2.0, in October 1995, introduced
frames, Java applets, and JavaScript. Version 2.0
was the last version of Netscape to introduce a
major feature of the web as we know it today; later
versions improved reliability and stability and
introduced features that did not catch on as standards
for all browsers. In 1998, Netscape decided to release
their browser source code as open source software,
and the Mozilla project began.

Microsoft Internet
Explorer is by far the most common web browser in
use as of this writing. Internet Explorer 1.0, released
in August 1995, broke no important new ground in a
way that became part of a future standard. Later versions
of Internet Explorer quickly caught up; Internet Explorer
3.0 was very close to Netscape 2.0's feature set.
In July 1996, Internet Explorer 3.0 beta introduced
the first useful implementation of cascading style
sheets, which allow better control of the exact appearance
of web pages. In April 1997, Internet Explorer 4.0
introduced the first quality implementation of the
Document Object Model (DOM), which allows Javascript
to modify the appearance and content of a web page
after it has been loaded.
