TV channels also rely on subscribers, I believe.

Having said that - I still think Facebook ads might work in the long run. While they are annoying, they are also highly targeted and will only get more targeted in the future.

Even the BBC (tax payer funded) has a (separate) commercial arm to make and sell programming.
