NPR (and their member stations) do not have advertising per se. Rather, they call it underwriting and there are very specific rules about what format the underwriting can take. Here are the guidelines: http://www.npr.org/sections/ombudsman/2015/03/11/392355447/nprs-underwriting-guidelines-part-one http://www.npr.org/sections/ombudsman/2015/03/11/392355447/n... I used to work at one of the largest NPR affiliate stations. Listener support is hugely important, most of the money we made came from listeners. IMHO, NPR is pretty successful in that they have built a model that supports quality journalism, at a decent scale, without a lot of annoyances for the user. Newspapers and other media orgs could stand to learn a lot.
