circulating course meaning in English

循行路线

But now the challenge to it has not existed , even the criticizers have accepted that audience is the commodity of mass communications . of course , we should realize that such theory too emphasizes the power of media and ignore that of audience and the competition between different media industries . furthermore , since there is another circulating course in which symbolic commodity is sold to audience and consumed by them , not only audience commodity but symbolic commodity is the commodity form of mass communications
但目前对该理论的挑战已不存在，甚至当年的批评者们也承认受众是大众传播的商品，当然，我们必须注意到该理论过于强调媒介力量，忽视受众抵抗和媒介间的竞争，而且，由于在媒介出售受众的过程中还蕴涵着向受众出售符号商品的流通过程，所以，受众商品并不是大众传播的唯一商品，符号商品也是它的商品。
