The article doesn't mention a rate at all or show data prior to 2011, so the headline should really be comparing differences between 2012 and 2011 and not mention 'rate'. I found Compete data for 2009-2010 (http://media.marketwire.com/attachments/201009/MOD-13263_image1.jpg http://media.marketwire.com/attachments/201009/MOD-13263_ima...) and have copied it below. Aug 2009 72.6% Aug 2010 70.1% (-2.5%) Aug 2011 68.3% (-1.8%) Aug 2012 65.7% (-2.6%) So, the percentage indicated in the headline isn't horribly inaccurate (Google's share also dropped by 2.5% between 2009 and 2010 and averages a 2.3% drop in market share per year over the past three years.)
