I want to know what the current "market share" of the major web
browsers is -- say Internet Explorer, Gecko-based (I'm particularly
interested in FireBird/FireFox), Opera, maybe Safari and "other". I
realise visitor statistics vary from server to server, so ideally I'd
like the answer to be based on data from several major popular sites,
or one mega-popular site (like! But zeitgeist isn't telling
me what I want to know). By "recent" I mean 2004 onwards -- I've found
plenty of stats from 2003. The most important point is the quality of
the statistics -- it needs to come from a sufficiently general
interest, popular site that it can be viewed as a reliable indicator
of the "general public".

Data from the same reliable source for a longer period (say the last
12 months) would be exceptionally interesting; I'm willing to raise my
price if you think you can get this data.

Dear seldo-ga,

What an interesting question, I'd be glad to help you with this
request.  I happened to make a very lucky search I think, because I
found your requested information on the first search.

According to The Aspect Group <>, for the
weeks of February 1-7 & 8-14, 2004, the following were the market
shares for the major browsers:

Browser | 2/8-13 | 2/1-7 | Change

Internet Explorer 6.0  61.49%  71.32%  -9.83    
Internet Explorer 5.5  18.40%  12.43%  5.97    
Internet Explorer 5.0  15.98%  11.49%  4.49    
Other/Unknown  1.47%  1.61%  -0.14    
Internet Explorer 4.0  0.62%  0.34%  0.28    
Netscape 4  0.50%  0.92%  -0.42    
Robots  0.44%  0.46%  -0.02    
Mozilla  0.38%  0.64%  -0.26    
Netscape 7  0.32%  0.36%  -0.04    
Opera  0.14%  0.17%  -0.03    
Proxy Servers  0.11%  0.14%  -0.03    
Netscape 6  0.07%  0.05%  0.02    
Konqueror  0.02%  0.02%  0.00    
Java Applications  0.01%  0.01%  0.00    
Internet Explorer 3.0  0.01%  0.01%  0.00    
Galeon  0.01%  0.01%  0.00    
Liberate DTV  0.01%  0.00%  0.01    
WebTV  0.00%  0.00%  0.00    
Lynx  0.00%  0.00%  0.00    
Netscape 3  0.00%  0.00%  0.00    
OmniWeb  0.00%  0.00%  0.00    
Teleport Pro  0.00%  0.00%  0.00    

Additionally, I provide the information below for your reference:

I searched the clustered search engine Vivisimo
<> with the following search terms:  2004 web
browser statistics

The first site I encountered appears to be exactly what you are asking
for, however, it only shows the current and previous week.  It offers
a list of 22 browsers, major players and less known browsers; and, the
convenient thing about this particular stat source is their stats are
gathered from over 600 web sites across the internet.

This site seems to offer everything you're asking for.  According to
their site, they offer "daily snapshots and historical trends of the
statistics listed below. In addition to global averages StatMarket
segments visitor data by 245 countries and 120 categories." The
statistics most relevant to what you are asking for are as follows,
although they offer a complete list at:

Browser trends - See the percentage of different browser versions that
are being used by the global Internet community. Understand browser
trends from a high level view down to a granular version level.

Operating systems - See the latest trends in operating systems. Find
out which system versions have the largest percentage of users.

The only drawback to this site is it comes with a price.  Pricing
information for this site can be found at:

According to this site, they will email you monthly statistics on the
following information, for slightly less than the above site: "Now you
can receive monthly reports on global internet usage trends,
comprising data on browsers, screen resolution, search engines,
connection speed, plugin coverage, etc, so you can be properly
equipped for the task in hand."

I hope you have found this answer helpful, please don't hesitate to
request clarification if necessary.

Kindest regards -- mosquitohawk-ga

Mosquitohawk -

Excellent work!

The aspect group data is very interesting, in that it's exactly the
*form* of data that I was looking for. A few questions about it:
- how did you determine the dates it is looking at? The site seems to
be no longer maintained (404 pages, and their main site has a new look
and feel which hasn't been carried over)
- what sites is the aspect group sourcing this data from? 13 million
hits sounds like a lot, but source is very important: I'm sure
Slashdot gets many millions more hits than that in a week, but I
wouldn't trust their stats to be representative

Much more useful is the browser news site ( ) since it's clear what
dates it's using and it's also very up-front about what sources it
uses. They also led me to the stats of TheCounter ( ) which is
very much in the vein I was looking for.

Incidentally, it amuses me that you didn't use Google itself to find
this information, but that's just an aside ;-)

Other than those two little clarifications, I have absolutely no
problem with this answer :-) Thanks a lot!

Greetings again Laurie,

I was able to determine the dates for the aspect data by a little
counting.  I visited a page on their site and it had two rows of
browser data for 2004 labeled week 6 and week 7.  I counted from the
first week in January and determined it was currenty the 7th week of
2004, so I made the presumption based on that the information was

I am unsure the exact sites that aspect is pulling their data from,
however, I will be glad to email them if you like and request that

I decided not to use Google because I saw another researcher had
already tried, and I have found the Vivisimo engine to be useful on
other occasions when Google (rarely) wasn't. It searches for
information in a slightly different way.

I found another site you may be interested in, publishes
their web statistics.  They receive much traffic :
