Video hosting/streaming is substantially more bandwidth intensive per-user than download hosting, in LTT’s defence.
This is probably why Youtube will remain a necessity, @Nordom. Rumours are that despite its ads and Red programs, YouTube still loses money for Google/Alphabet. If so, Google probably allows this because YouTube’s dominance in the market provides, in effect, promotional value for its other services.
The scary reality is that if Google is unable to make a free video hosting platform viable, no one likely is. I have no doubt that Google custom builds servers, likely with FPGAs and/or custom silicon accelerators to operate YouTube infrastructure at maximum efficiency; I doubt Floatplane or any other startup will be able to keep there costs anywhere near YouTube’s. In fact, when you see Google’s push for better (and rotalty-free) codecs like AV1, this is in no small part motivated by trying to cost-reduce YouTube; it is useful that smaller files decrease storage and bandwidth, even if video processing time goes up; one time costs increase while recurring costs decrease.
Of the other video hosting plaforms that I can think of,
Dailymotion, NicoNico, Vimeo, Floatplane, Odysee, Rumble, Bitchute
outside of YouTube, many have some caveats or limitations. As for newly created services, is difficult to know whether they are profitable or merely have yet to run out of investment capital.
There are also other services which host only shorter videos, or only retain videos for a limited time:
Meta (Facebook, Instagram), Twitch, Twitter, Douyin (Tiktok), IBM (Ustream)?, Snapchat?
Facebook may very well host lengthy videos, but I classify it here since videos are not really the core service.
I do not see how this landscape significantly changes until storage and bandwidth is an order of magnitude cheaper; however, there is a chance that video hosting which makes use of P2P might remain viable where others cannot. Peertube, for example, does this, but it is also more of a server package for people or groups to host their own video, rather than a public general-purpose video sharing site. I do not know if its server costs make widespread adoption viable.
