What many forget unless they were from other parts of the globe, is that IE was the first international browser supporting non-European character sets etc. Netscape took too long to realise that it had forgotten to support the first two Ws in WWW and so even when AOL bought Netscape, the AOL browser had to be built on IE technology to support international customers.
It's not a lesson well learned. Other browsers are still full of code that assume WWW=USA.
