protocols were being developed

Mosaic
Mosaic goes on to become Netscape
The commercial arm of NCSA licenses
their Mosaic to Microsoft
This heralds the start of the browser
wars

15. HTML HELL
The browser wars
HTML and
the Internet

16. HTML HELL
The browser wars
Both Netscape and Microsoft try to
achieve a competitive edge by:
Producing new features without
fixing existing problems
Adding features in direct
competition with other browsers
existing features [what!]
Adding Proprietary features
Private ownership or control over an item

17. HTML HELL
Developers
The wars meant that web developers
had to do one of two things:
Produce two different but
effectively duplicate sites
Support one browser blocking
the other
A backlash was inevitable

18. HTML HELL
The coming of
web standards
HTML and
the Internet

19. HTML HELL
World Wide Web Consortium (W3C)
Founded in 1994 to address the need
for new markup languages and
standards
It is a grassroots coalition fighting for
standards that ensure simple,
affordable access to web technologies
for all

20. HTML HELL
Its lofty aims are:
Device independence and web
accessibility
Access to web by any means as
easily as from a desktop PC
A knowledge base to solve
complex problems
A collaborative environment to
inspire trust and confidence

21. HTML HELL
Why use standards?
Greatest acceptance and uniform
display of content across a
multiple of browsers and OS
More meaningful to search
engines
Greater chance of being
accessible in future applications

the internet
