Funding for the Corporation for Public Broadcasting represents 0.014% of the federal budget. That's under 2 hundredths of one percent. All Things Considered, Morning Edition, Sesame Street and the other big programs would all survive without federal funding. Why? Corporate "underwriting." Do you know what that means? In the free market, corporations have realized that there's financial incentive to having their name and message attached to these programs.
I'm sure you've heard of the hundreds (yes, hundreds) of advertisers who refuse to let their ads run during "controversial programming." GM isn't a Rush advertiser. Neither is Pfizer or AstraZeneca, two of the country's largest drug makers. NBCUniversal, IBM, Monsanto, Netflix, and dozens more... all companies that avoid Rush, Hannity, Savage, Howie, whoever.
Do you know who these companies do spend their money with?
NPR.
That's probably because their programming doesn't have the bias many believe it do have. Choose your reason why they put their money behind NPR, either way you're wrong.
