It seems that NetApplications in June changed the methodology of how it weights data, giving more prominence to page views globally based on the estimated size of each country's Internet population rather than focusing mostly on the U.S. and other Western markets, which is why there was no June report and why the statistical picture has changed radically.
For example, using their old system, in May Apple enjoyed a 9.77 percent operating system market share — more than 10 percent if you included the iPhone. With Net Applications new methodology of tabulation, the Mac's share drops to just 4.73 percent or 4.98 percent counting the iPhone. At the same time, Windows spikes from 87.80 percent share to 93.18 percent.
The change in calculation mode has been applied retroactively to previous data, and Net Applications has http://marketshare.hitslink.com/weighting.aspx explained in a posting on their Website that "we adjust our reports proportionally based on how much traffic we record from a country vs. how many internet users that country has. For example, although we have significant data from China, it is relatively small compared to the number of internet users in China. Therefore, we now weight Chinese traffic proportionally higher in our global reports. This change produces a much more accurate view of worldwide usage share statistics."
They also note that after consulting with many of the organizations they report data on, they've decided to use C.I.A. data as the source of the number of internet users per country, and that from now on, a single high growth country will not be able to affect the global share numbers.
Specifically regarding Apple stats,, they note that since Mac share in the U.S. in significantly higher than the rest of the world, Mac and Safari share drop in the global reports. However, the overall trend line remains consistent, with Windows slipping 0.4 of a point over the past 90 days and the Mac OS gaining 0.2 of a percentage point during the same interval, and Apple's share in the US remains about 10 percent.
So here's the Operating System Total Market Share rundown of the significant players for July based on the new calculating methodology (old methodology May '09 figures in parentheses):
Windows 93.04% (87.80%)
Mac 4.86% (9.77%)

Browser Share
Turning browsers, there's some good news for my favorite browser, Opera, which more than doubles its share to 2% based on global reports reflecting the significant penetration the browser enjoys in Eastern Europe and Asia. The Firefox browser still has in excess of 20% share under the new, globally focused rules — its calculated share barely changing, but Safari fared much worse, dropping from 8.43% in May under the old system to just 4.07%. Internet Explorer gained a couple of points with the switch, while Google's newcomer (and so far Windows-only) Chrome, like Opera, roughly doubled its percentage compared with the old calculation mode.
Browser Total Market Share (May figures in parentheses under the former calculation methodology):
Microsoft Internet Explorer - 67.68% (65.50%)
Firefox - 22.57% (22.51%)
Safari 4.07% (8.43%)
Chrome - 2.59% (1.60%)
Opera - 1.97% (0.72%)
Netscape - 0.67% (0.74%)
Opera Mini - 0.29% (0.08%)
Mozilla - 0.07% (0.10%)
Konqueror - 0.05%
