X unveils video-centric TV app to rival YouTube - Dexerto
(www.dexerto.com)
This is a most excellent place for technology news and articles.
It sounds like a YouTube clone from the article, so long form videos storage and streaming isn't cheap, a lot more expensive than what x usually hosts in terms of bandwidth and storage per views. But yeah also seems like a niche use case.
Still no way there's a net cost benefit to video hosting from as revenue.
