Internet Explorer has less than 50% share of all web browsing

"Internet Explorer can no longer claim more than half of the web’s traffic, as of October, ending more than a decade of the default Microsoft browser’s reign.
Safari’s hold on 62.17% of mobile traffic has reduced IE’s overall share of web browsing, despite still claiming 52.63% of desktop traffic, according to Netmarketshare.com.
The Microsoft browser’s diminishing share (49.6%) reflects its near absence from the realms of mobile and tablet, which now make up 6% of web traffic. However, chances are, you gave up on IE long enough ago that this milestone makes you more curious as to who actually still uses the browser.
As of October, Firefox is the second most popular web browser, accounting for 21.20% of traffic, followed by Google Chrome and Safari, which account for 16.60% and 8.72% respectively.
Chrome, which recently celebrated its third birthday, experienced the most expansion in October, increasing its share of the desktop market 1.42%.
Safari, the default browser in Apple’s iPhone and iPad, continues to increase its dominance over the mobile web, gaining 6.58% of the market. Safari’s share is increasing faster than the iPhone’s, probably due to how much mobile traffic is now driven by iPads."

"In this month’s State of the Mobile Web report, we are highlighting a major milestone in the growth of the mobile Web. When we combine the number of people who used the Opera Mini browser (90.36 million) in January with the approximate number of Opera Mobile (15 million) users in January, we get over 100 million people who are using Opera browsers on their handsets. That number only includes people who have downloaded the public version of the Opera Mini browser; it does not include people who use Opera Mini instances that are preinstalled on phones by operators. As such, 100 million is actually an underestimate, but we are not concerned, as that number will be eclipsed shortly. Opera Mini’s increasing growth rate over the last five years has been nothing short of astounding, and our expectations are high for 2011 and beyond.
Consider these numbers:
Between January 2006 and January 2007, the number of Opera Mini users increased by 1.9 million.
Between January 2007 and January 2008, the number of Opera Mini users increased by 5.3 million.
Between January 2008 and January 2009, the number of Opera Mini users increased by 12.4 million.
Between January 2009 and January 2010, the number of Opera Mini users increased by 29.8 million.
Between January 2010 and January 2011, the number of Opera Mini users increased by 40.6 million.
Based on that growth trend, we think there is legitimate cause to say that mobile web browsing is the wave of the future, a future we are helping to create via our mission of providing the best Internet experience on all devices."
