Achieving pubilc service pluralism in the Unites States context is so idiosyncratic, so much a product of particular historic and governmental developments, that it is diffi cult to draw lessons that are useful for the United Kingdom. The differences are rooted in the distinct (1) role of federally licensed commercial stations; (2) expectations about the contributions of public broadcasting to pluralism in program offerings; and (3) structures of public broadcasting. In this brief essay, we try to show what aspects of pluralism and diversity are valued in the very special case of US media policy and how the idea of public service plays out at a time when an increasingly fractionated society faces a fractionated array of media offerings.
