In its radio fund- raising campaign, National Public Radio (NPR) stated, “ On- air radio membership campaigns are the most cost- effective means we have for raising the funds necessary to bring you the type of programming you expect.” NPR is commercial- free, member- supported radio. Most of its operating funds come from private individuals, corporations, and foundations. Twice a year it interrupts its regularly scheduled programming for fund- raising pledge campaigns where listeners are encouraged to call in and make pledges.
