Internet Explorer 6 … not dead yet.
The internet is a great medium for users to be able to access choices in just about anything they can think of. One of these choices is the application used to browse the web, the web browser. There have been battles in this area for years, often resulting in court action and sometimes in the demise of the product. Just like you “know” your detergent is better than all the others, you also know your chosen web browser is the most secure, fast and friendly browser available.
There are a number of web browsers available at the moment, such as the incumbent market leader Microsoft Internet Explorer and the “new kid on the block”, Google Chrome. Other browsers exist, each targeting specific features such as speed, platform (mobile phones, etc.) or privacy. The chart below from MarketShare illustrates the performance of each browser in the last 2 years or so. (Download the PDF)
As various versions of the web browsers are released and market-affecting court action is announced, it is clear how browser share is affected, particularly with the decline of Microsoft Internet Explorer version 6 and 7 (towards version 8 ) and the increase in adoption of alternative browsers. The recent European Court ruling that users should be given a choice has resulted in Windows 7 users being presented with a browser election screen will be more forceful in that choice, giving users who wouldn’t otherwise be aware of alternatives the opportunity to move away from the “operating system browser”, Internet Explorer.
This choice is good for the user, but presents us with challenges. We need to embrace the latest technologies such as those offered by HTML5, but this needs to be tempered by implementation of those technologies by browsers and ability for older browsers to be able to provide an equivalent experience for users. A challenge any web developer [should] have is being able to facilitate users of Internet Explorer 6 (”IE6″). IE6 has been around for years. Shipped as part of Microsoft Windows XP, it is “stuck” in that users of Windows 2000 who upgraded to IE6 cannot upgrade to IE7 and corporate/enterprise users can’t perform upgrades themselves and as such are restricted to whatever the IT department dictate. Therefore, there will be a “hardcore” contingent of IE6 users for years to come yet, particularly as official support for Windows XP (and therefore IE6) only ends in July. These users need to be catered for, regardless of your market persuasion.
This morning, Scott Hanselman drew attention to a CNN article claiming that Internet Explorer 6 was about to die for good, having decreased to 4.7% of browser market share in the US. This seemed to be very optimistic, based on the figures we have seen. Our understanding, provided by MarketShare and being a global metric, is that IE6 continues to retain 17.13% of the browser market share. (Which also illustrates the disparities in statistics collection) So while its death is surely coming, it’s too early to arrange the wake and we will continue to support IE6 in the meantime for the sites we develop.
