Just to be clear, when it comes to radio audience, the audience is 100% local stations. NPR does not own any radio spectrum. The structure is that local stations have complete editorial control of their programming so long as it adheres to the principles of the NPR mission and in exchange they get access to the network of content produced by NPR and local affiliates. Bigger affiliates like the ones in Boston produce a lot of local content or even sell back to the national network, while smaller ones are mostly running NPR content. They are also all running their own budgets and revenue operations.
