Romney just said he'd get rid of PBS and NPR

23. Funding comes from multiple sources...

...and federal expenditure is quite limited. Here's one article on the subject:

Funding public media: How the U.S. compares to the rest of the world

Though cutting public broadcasting appropriations to the Corporation for Public Broadcasting would essentially limit the “public” nature of our system by cutting out the government, it’s important to remember that most public radio stations receive only about 10 percent of their money from CPB. For many public radio stations, though, if it comes to it, the loss of this federal money may make it all the harder to sustain local programming — and local newsgathering — if it cannot be found elsewhere.

I'd note too that nowadays for-profit media are making cuts in reporting staff and trashing radio formats even when said formats make money. The fantasy, which Romney seems to believe, is that whaterver makes money will survive and thrive, and deserves to. But the truth is of course more complicated than that.
