广播这个现代化的大众传播媒介的信息传播者同自己的受众之间的距离并没有因此而缩短,这是因为,反馈始终是各种大众传播媒介的一个薄弱环节,也是广播的先天弱点。有时,我们同自己的听众远隔千山万水,自然难以进行信息交流,有时虽在咫尺
The distance between the information disseminators broadcasting this modern mass media and their own audiences has not been shortened. This is because feedback has always been a weak link of various mass media and an inherent weakness of radio. Sometimes it is natural for us to exchange information with our own listeners, sometimes close at hand
