There's many company-intern intranet applications still in use out there, which rely on old IE features like ActiveX and whatnot. Afaik, older versions of .NET came with features that required IE.<p>Also Asia always was and to my knowledge still is using a lot of IE - not sure about the reason why.<p>A little history lesson:<p>* Netscape wanted to dominate the web, gain a monopoly and gain full control.<p>* IE came late to the party - long after Netscape was already established<p>* MS invested a *ton* of resources to catch up, rapid development pace, quick updates, constantly new features and improvements<p>* MS too wanted dominance and full control of the web<p>* MS gained marked share through "dirty tricks" leveraging their OS dominance<p>* MS got repeatedly sued for unfair competition, paid large sums, paid lip-service to the courts but never truly changed their strategy<p>* that hurt Netscape but didn't kill it<p>* what killed off Netscape was their own doing: a costly code rewrite, that took way to much time and delivered subpar results<p>* Microsoft won, they had what they wanted: full control of the web, and the power to shape it however they saw fit<p>* they did nothing. they just stuck with IE6, no new features or improvements for years, even bugfixes and security fixes became really slow. all momentum was lost.<p>* Firefox rose from the ashes of Netscape - MS still did nothing.<p>* Firefox gained significant market share - that finally kicked MS into gear<p>* MS re-started updating and improving IE - but they were technologically behind and had to play catch-up again<p>* Chrome entered the ring and boosted the pace of development<p>* IE never fully caught up<p>* Chrome gained full dominance of the market - but unlike IE did not slow down development<p>* MS tried all their dirty tricks again - but they still continued to loose market share<p>* they rebranded IE to Edge (still using the same render engine, but dropping backwards compatibility)<p>* they dropped their own render engine, and switched to using webkit<p>* despite even more dirty tricks, no breakthrough success in terms of market share<p>I believe the fading of IE pretty much started with Microsoft resting on their (un-earned) laurels, after Netscape died. And yes, that's even before IE peaked - while they still had upwards momentum.
