IE 6 was once the most popular browser on the market. This despite its lack of adherence to standards and its poor rendering performance. These days it’s on the way out, and no-one in IT is mourning it. The graph here shows the trend of IE 6’s market share over the last year and a half (source: http://www.w3counter.com/globalstats.php).
The story’s not that simple though. Corporations still persist in forcing their employees to use the browser, doubling its share during working hours, and Microsoft have still committed to supporting it for some years yet. Problems with an attack on Google via IE6 security flaws in December 2009 don’t seem to have galvanised companies into ditching it, but maybe Google’s subsequent withdrawal of support for IE 6 in GMail and other Google Apps “later in 2010” will accelerate this.
