Quite a bit? You have a lot of videos, most of which in many formats, often up to 4k. Storage alone likely costs a few pennies (if not more).

Then all the network traffic (a sizable fraction of the entire internet traffic), transcoding & upkeep for all these things. That's only VoD.

Then there's live video which is basically the entire thing above with the additional constraint that there's less room for error and latency.

Some other services tried live video as well, e.g. Netflix or Apple for some keynotes in the past.

For Netflix I recall a few were covered in the media, e.g.: https://www.theverge.com/2023/4/16/23685828/netflix-love-is-....
