We have basically have 2 television broadcasters: The national broadcaster SABC (which is free) and a private satalite based system DSTV (+- 80$).
More and more local content is being made and is being broadcast mainly by SABC. It is mostly rubbish. DSTV, however licenses a bunch of American and British channels and content.
Due to the terrible state of broadband here (I wish I could get 50 GB a month. It is more like 3 GB on average.), watching TV is the only sustainable method of content delivery (that and leaching at lan parties).
