大众传媒是职业传播者搜集、制作并借助媒介传递信息，并　对受　众施加影响的一个过程。它是受众社会化的重要媒介，人们可以通过其获得信息、知识和技　能，学习社会规范和扮演社会角色，从而促进个人社会化的发展。但大众传媒的商业化倾向　及其派生的＂离间效应＂对受众社会化也有许多负面影响。 The mass media is a process in which professional communicators gather, produce, and use the media to communicate information and influence audiences. It is an important medium for the audience’s socialization, through which people can acquire information, knowledge and skills, learn social norms and play social roles, thereby promoting the development of individual socialization. However, the commercialization tendency of the mass media and its derived “off-line effect” also have many negative impacts on the socialization of the audience.
