As part of a recent fund raising pitch by San Francisco’s premier public radio station KQED, the announcers directed their listeners to this site on the radio’s web-page which I had previously not known about.
I found this a particularly effective way to raise contributions since it demonstrated how much KQED was itself “giving back” to the community.
It is a perfect example of new media’s “Gift Economy” at work. From KQED - San Francisco click on KQED Education
Note that contributions to public radio and television are actually referred to as gifts and are both voluntary and tax deductible.
