I’m assuming the viewers would be charged from what I read. And they would only be charged for pay channels and tv shows, as @Dr_Lawrence mentioned.
They will probably be more vigilant about taking down copyrighted material, which would bum me out since my daughter loves Mickey Mouse Clubhouse and this is the only way we can watch any episode other than “Roady Rally”... I HOPE all these clips and ads I see for the Disney Jr “channel” on YouTube that always pop up means that there will be a Disney Junior station. I’d probably pay to legally watch most of the shows I see advertised on it.
