The Browser Market Share White Paper data is by month starting in
September 1997 through the March 2008.
Between March 2007
and March 2008 Microsoft’s Internet Explorer (IE) market share has
shrunk to 60% -- A drop of almost 9% in 12 months. Firefox and Google Desktop have been the main
recipients of this change in market share. Based on the data Microsoft
has a continuing issue associated with its eroding browser market
share percentage. In the meantime NS version 8 has been a
colossal flop.
Firefox has continued to see gains in its market. One
clear advantage that Firefox has is the amount of memory that it
uses. This becomes extremely important as user get more “add-ons”.
Another is that fact that it is not a Microsoft product.
Firefox had better keep looking
over its shoulders to make sure they stay ahead of Google Desktop or
they may become the next Novell or DEC.
