Compared to similar data collected in 2007 we can see that Microsoft has maintained its' lead over Apache; while it is even more apparent that Netscape is falling off the map.

Our research shows that IIS 6.0 continues to be the most popular choice among IT professionals at the leading Top 1000 companies grabbing the majority of sites upgrading from IIS 5.0, which is rapidly being decommissioned. Meanwhile, IIS 7.0 is gaining in popularity with its expected adoption among the Top 1000 companies just beginning.


An important note on Web server identity

Before looking at server market share in more detail, it is important to note that the vast majority of the Top 1000 Corporations' Web sites identify their server software platform in their standard HTTP header response, and thus fail a basic security test.
