According to Net Applications , an authority on Internet browser usage statistics, Internet Explorer (all the versions added together) is continually losing market share, and has finally dropped below 60%:
Meanwhile, as you can see from the graph, Firefox’s market share is at 24.59%, Opera and 2.3%, and Chrome at 6.73%. Chrome had the largest increase in market share at a increase from 2.4% only last year. This chart  gives a better idea about the browse usage trend over the years:
It is interesting to note that other sources, such as W3Counter , say Internet Explorer market share is even lower than the 59% stated by Net Applications:
Further it is even more interesting to note that Firefox has already surpassed Internet Explorer as the most popular browser used by dotTechies (50% vs 30% roughly).
Of course no one knows exactly why Internet Explorer is losing market share (it is impossible to know exactly), but chances are it is because
- Other browsers, such as Firefox and Chrome, are offering enhanced features via extensions/addons. Internet Explorer also supports addons, but not to the extent of Firefox and Chrome.
- Other browsers are boasting better speeds.
- Awareness among users is being raised to the fact that Internet Explorer is not the only browser out there. Internet Explorer has a really bad reputation (particularly thanks to Internet Explorer 6) so when users find out about other browsers, many make the move.
