> Youtube is still a dominating player even though we have HTML5 video support in all browsers.

It's not like widespread HTML5 video support marks some significant change in the landscape. We had flash support in all browsers forever; that's how youtube came about in the first place. It wasn't difficult at all to make another website that also served flash videos. It still isn't.

What youtube does that's difficult is agree to host the content. HTML5 does nothing for that.
