It did. But Microsoft disbanded the IE team after they won that marketshare, which gave other browsers years to catch up. Things may have looked very different had they continued the heavy development pace after releasing IE6. IE had a fast and modern engine compared to contemporaries when IE6 was first released, but then it went five years without any major updates. I'm undecided about Google's growing browser control, but in any case I don't see Google making the same mistakes as Microsoft.
