If you go to go to countries in Europe or Asia or even Canada, even with all the Internet and cable TV and satellite, public systems tend to be the most popular stations in the countries. In some countries like Norway and Germany, public stations are, if anything, more popular than ever as people see what Rupert Murdoch's got in store for them in the commercial stations.

In the US, commercial interests stole the airwaves early on, before public broadcasters could get a stab at it. And the deal that was made with public broadcasting was, "Okay, we'll allow there to be a handful of public stations to do the educational programming that commercial broadcasters don't want to do, but the deal is they can't do anything that can generate an audience, anything that's commercially viable." Anything they do that could be commercially viable could be considered unfair competition to commercial interests and should only be on the commercial stations.

Very rarely are you going to see the large shareholder or CEO of a corporation march into a newsroom and say, "Cover this story, don't cover that." It's a much more subtle process.

If you're running for reelection in the House of Representatives race, you know, it's very important to you that you be on fairly good terms with the local affiliates in the largest market in your area. I mean you don't want to antagonize them.

The public gets not one penny from them in return for those airwaves.

The commercial broadcasters have tremendous influence in Washington, D.C., for a couple of reasons. First, they're extremely rich and they have lots of money and they have had for a long time, so they can give money to politicians, which gets their attention.
