I have noticed that Korean shows are online immediately (licensed sites like Viki and DramaFever pay for them with a few ads) upon airing and volunteers add subtitles to them.
This would work for US shows too, I would think
The free link sites are full of ads and pop-ups too, I doubt any of that revenue goes for copyright payments though I could be wrong. I don’t see those ads because I have a host manager and pop-up blocker.
But the original ads in the recorded show couldn’t be blocked, though one could advance through them.
And the networks could charge more since ads are priced, partly, by how many see them.
