Browser and Operating System Market Share White Paper
Firefox - IE - Opera - Mozilla - Safari - Google Chrome
The Browser Market Share and Operating System Market Share White Paper data is by month starting in September 1997 through November 2011. The data sampled is internationally based (Just under 50% of the data points sampled are outside of the United States).
November 2011 White Paper
In the last several months Microsoft's browser market has continued to decay. Firefox and Google (Desktop and Chrome) continue to have the potential to eat away at the Microsoft browser monopoly and Firefox's market share.
Users who move to Windows 7can more readily have multiple browsers on their systems and switch from one to the other quickly and with little pain. In addition with the release of the browser ballot option for the EU we forecast there will be a continual erosion of Microsoft's IE market share.
Based on our test results current versions of IE and Firefox are significantly more robust than prior versions. In addition, IE 9 is feature rich and a step ahead of the other browsers. Chrome has major defects which limits its usefulness on all sites. Several of these defects are highlighted in this White Paper.
Adding some heat to the Browser fire, Microsoft has announced that they will be adding a spell checking feature to IE 10 which can be previewed in its Beta Version.
12 Month Trend in Browser Market Share

However the acceptance of IE 9 has been much slower than prior version of the Microsoft browser. One of the prmary reasons that its acceptance has been slow is the lack of a spell checing feature.

Microsoft IE Market Share Decline

Google seems to be the big winner
Google Chrome has taken off, while interest has waned for its Desktop product. Based on these trends we believe that Desktop will no longer be a force in browser market.

Google's Chrome offering, now commands almost 10% of the browser market and viewed by some as the browser of the future.

Operating Systems
Janco has found that almost 40%of the entire OS market is taken up buy Windows 7 and Vista.

In addition, Windows 7 has a much higher acceptance rate than Vista.
Windows 7 is Widely Accepted

A full discussion of this trend as well as others is contained in the detail report. This data is updated in the full study. The data in the study is through October 2011.
