Here is an intresting view on the marketshare across different browsers.

All the data comes from the I used worldwide marketshare of each popular browser from Feb`11 to Oct`11 and the marketshare of each version available in the reports from Net Applications. Having both you can easily compute fragmentation amoung various versions of the same browser – that is exactly what I did and you can find my result bellow:

 Few important points:

  • there is some blank space on the top of graphs – that is because I didn`t include additional variations like Maxthon versions of Safari and IE and also Net Apps does not show in the report browser versions with too low marketshare.
  • for Opera Net Apps aggregates all 11.x, 10.x and 9.x versions – so there is additional fragmentation not reflected in the graph.
  • this data aggregates thru all operating systems – it is important because not all browsers are available on all operating systems and fragmentation on each of them is also intresting to discuss :)

Lastly, I don`t like to discuss here:

  • which browser is better (personally I love IE :P),
  • which update engine works in the best way (yeah, I know autoupdate at first look seems to be great, but it is not the same in different browsers as you can see on the graphs above and it also does not work in the same way across all the audiences and – this is the most intresting and maybe also unexpected – it produces slowly growing additional fragmentation, and finally there are many security considerations you should also take into account before you will try to convince everyone around you on that it is the only right way to do updates), or
  • total marketshare of any browser and any version (you know it – IE9 is going to become leading modern browser on Windows 7 and already does it in some countries and like you I`m also waiting for the day when IE6 marketshare will countdown to zero).
