In the previous installment in this series, I looked at the browser share in North America. Across the water in Europe, the browser distribution metrics show the unique flavor that this continent brings to this fluid arena.

In Europe, MSIE7 and Firefox 3 are effectively tied for the lead as the most dominant browser, followed distantly by MSIE6. As in North America, MSIE8 has substantially increased it’s market share since its March 19 2009 release, but it has not caught up to Europe’s favorite son, Opera 9.6.

What is clear is that MSIE8’s gain is MSIE7’s loss. Comparing March 1-19 with April 1-19, the shift away from MSIE7 is almost equal to the shift to MSIE8, meaning that people that are upgrading to MSIE8 in Europe are doing so, in the most part, directly from MSIE7.

There is little or no change to the MSIE6 install base, indicating that this is an entrenched population, likely in large corporations or government agencies.

Like in North America, the big factor to watch is how quickly the MSIE6 population decreases. Europe already has an entrenched population of alternative browser users, mostly with Firefox 3. When Opera 10 and Firefox 3.1 are released, it is likely that these people will move directly to these browsers.

What remains to be seen is how the strong anti-Microsoft sentiment in Europe affects the adoption of MSIE8.

Tracking browser penetration and market share has become a new obsession with me. With 2009 shaping up to be the year of the browser container, the choices that people make will affect the development of Web technologies for the next few years.

So far, the only new player to come out of the gate as a production release is MSIE8. Since March 19, MSIE8 has seen a slow and steady increase in market share, at least in North America. This has occurred, as I have noted previously, without the support of Windows Update, which will drive millions of users to automatically upgrade their systems.

What can be seen in this data from StatCounter is that MSIE8 is finally (Thank [insert deity or supernatural object here]!) taking market share away from MSIE6. As the corporate browser of choice (mainly because IT departments don’t have the resources or initiative to sign-off on MSIE7), MSIE6 is the default platform that all developers are forced to lower their standards to.

One can hope that IT departments will allow their customer base to make the leap directly to MSIE8 from MSIE6. We can all celebrate now, as the StatCounter data now shows that MSIE6 has dropped below 10% market share.

What is more interesting is that Firefox 3.0 made a serious encroachment into MSIE7 near the end of March. I am not aware of what may have caused this, and would be interested to hear if the StatCounter team has any insight into why this may have occurred.

In the 10 days since its public release, MSIE8 has made a run up the charts. Courtesy of the great folks at StatCounter and their public analytics data, this growing browser share for MSIE8 can be easily followed.

In the US, prior to its release, MSIE8 RC1 was in sixth position behind even the old battleship Firefox 2.0, but ahead of Chrome 1.0.

In the week following its release, MSIE has quickly surpassed Firefox 2.0 browser share in the US. I am not really sure who these Firefox 2.0 users are, but they and the MSIE6 users must be found and encouraged to immediately upgrade.

The values for the first week don’t tell the entire story. As it enters its second week of general availability, MSIE8 continues to increase its share of the browser market, moving into fourth place in StatCounters US stats, overtaking Safari 3.2.

What does t his mean? While it still has a long way to go before it comes close to approaching even the dinosaur, MSIE6, it has to be said that this growth in MSIE8 browser share has occurred without the use of Windows Update. People are making a conscious decision to switch to and use MSIE8.

Site and application designers will need to take heed – MSIE8 compatibility initiatives will have to be in place yesterday rather than some vague time in the future.

Tomorrow morning, at 09:00 PDT, Microsoft unleashes IE 8.0 on an unsuspecting Internet.

By 12:00 PDT, the number of Web sites having to put up IE 7.0 only stickers will be in the millions.

I haven’t done a lot of testing of the new monster (I mainly use Firefox on Mac OS 10.5.6), but it doesn’t seem any weirder than any of the other Microsoft browsers I have used.

Under the hood, it does amp up the number of connections that are used to download objects, but if your infrastructure is prepared, it should be no big deal.

The big concern lies in the rendering. If those users who can upgrade to the new browser (anyone not limited to IE 6 by a corporate IT policy written on parchment) do find there are problems, will they blame the site or the browser?

Have you tested your site to ensure that it actually works with IE 8? Or will you get burned?

What is the greatest benefit you see to your visitors having IE 8 instead of IE 6 or 7?

Is this a good thing?
