The innovations of Internet Explorer
Say what you want about Microsoft and IE (I'm expecting Microsoft to be bashed as usual in this thread), but for those of us who were developing for the web in the early 2000s IE was way richer in features that any other browser.  The event model and the styling capabilities were better and best of all MSDN actually had documentation.  There's a reason why IE6 was adopted so much.  It "was" good.<p>Others with better ideas came along and made the web development experience better, but I agree that IE started it all.  I have no idea if the web would be better or worst without IE.  I would expect that someone else (Netscape??) would have played the role of IE if it didn't exist and we would be stuck in a similar situation.  Remember that in the early 2000s developers that called themselves web developers had ZERO experience.<p>There weren't any standards back then and since many of us had to start writing intranets and websites, and since you could do more with IE6 we used it.
