Microsoft tried to make "the internet" solely compatible with IE, back in the nineties and early two thousands.
They tried to kick Netscape Navigator by forcing every Windows user to use IE, and tried to use web sever - client communication and application techniques like ActiveX.
They even made sure that their only true desktop competitor (Mac OS X) had Internet Explorer as the default browser. (the browser of choice!
)
They came very close!
IMHO, there are just two reasons for them not completing that objective:
1. Firefox
2. iOS
FireFox came and grabbed the desktop market by storm, giving Windows, OS X and Linux users the true meaning of "OS independent".
This gave more web site developers less reason to use IE - only stuff like ActiveX and "the internet" became more and more OS independent.
iOS gave us "mobile internet", hugely leaning on Safari.
These two forces meant users of different platforms could use all web sites on most browsers.
That is what I call "choice"
It looks like Microsoft is really being different (thinking different..) now. Office 365 online and multiplatform, and moving away from that stained name "Internet Explorer".
NeXT up: Windows 10. And no more "big upgrades"....
