Television in a digital age: what role for public service broadcasting?
探讨数字时代公共服务广播是否仍有必要及其形式，提出衡量其绩效的指标，并分析专用公共服务广播机构（如BBC）的合理性。
The television broadcasting industry is subject to an exceptionally high level of public intervention, but one of the reasons for this, the absence of competition, is fast disappearing as households become multi-channel. This paper is concerned with whether a case for public service broadcasting remains and, if so, what form it should take. There are several other potential sources of market failure, but a lack of evidence often makes judging their practical significance difficult. To help overcome this problem and provide the basis for improved public accountability, the paper proposes several measures of public service broadcasting performance. The paper also considers when the appropriate remedy for these failures might take the form of dedicated public service broadcasters like the BBC, RAI, ARD, France 2, etc. It suggests that, in general, targeted supply side interventions of this sort only make sense when they address a supply side failure and that dedicated public service broadcasters are to be preferred to alternative types of targeted intervention, like an ‘Arts Council of the Air’, on contractual grounds.
