Because it is their own product, and it could be seen as a negative move to not use it?

And they can absolutely use it as a fallback for HTML5 video.

Using WMP Plugin, RealPlayer plugin, QuickTime, Flash, etc. is so... 2007.

MS also has(had) Silverlight but at some point they just stopped using it and most of the videos I've seen recently on their site(s) are HTML5 (no plugins required).

But not Apple. Everything (I've seen) on their site is QuickTime.

What browser are you using? Everything shows up as HTML5 video for me.

Chrome. On Ubuntu.

That's weird.

I actually know a couple of PC users who use it as their primary video player. I don't understand that, since I've never successfully played a single video with it. Granted, I gave up trying and switched to VLC about 6 years ago.
