Occasionally developers contact to ask about platforms/operating systems/versions/web browsers that are used by readers.

Recently I was asked about web browsers and so I contacted a number of scientific databases, scientific app developers, web sites. They were kind enough to provide information but asked that the details were not made public. The 12 sites range from 10's of thousands of hits per month to many millions hits of hits per month. The data shown below is from Jan 1st this year. It appears that Internet Explorer has almost disappeared as a mainstream browser.

Some people reported that they felt the drop in IE use was due to poor javascript performance.

Update

I've just been sent this image which also serves to underline the dramatic fall in the use of Internet Explorer (at least among chemists).
