Not really. Vimeo shows that you can corner niche markets successfully.

Profitability and growth aren't dependent on market dominance, even in tech.

YouTube Vimeo is more like 1% / 99%. By almost anybody's definition, that's winner take all.

Again, success isn't measured by marketshare, but profitability and growth. Vimeo has 15% of the embedded market by domain, and has managed to be profitable.

Even in your article it talks about how Youtube isn't exactly profitable, and is dragging down Google's average CPC for the business.

A massive difference indeed, but by any other standard, $100 million is not bad at all.

This isn't a good comparison. Netflix, Twitch, Snapchat, Facebook/Instagram are.

Well at least that’s what companies that are losing lots of money like to tell their investors. I’ve heard it many times and can’t think of any definite examples.
