In the U.S., community radio stations generally have smaller budgets than National Public Radio (NPR) network outlets, due to the smaller audiences attracted by their diversified programming and in turn, the small number of potential contributors and business supporters. Community stations are distinct from NPR stations in that most community-radio programming is locally produced by non-professional disc jockeys and producers, whereas traditional public stations rely on programming from NPR and other outlets (such as PRI). However, some community stations, such as KVNF in Colorado and WDIY in Pennsylvania, carry NPR in addition to their volunteer-based local origination programming.
