There are several models for paying for public broadcasting. You can charge a television license fee on the right to receive signals (e.g. the BBC), have funding from the government (e.g. the CBC), have commercials (e.g. CBC television), and you just hold pledge drives (e.g. PBS). Of course, you could have no public television at all.
