Broadcasting, as distinct from wireless communication, may be said to have come into being about 1920. It may be defined as the systematic diffusion, by radio telephony, of music, lectures, drama, humour, news and information bulletins, speeches and ceremonies, pictures and other matter susceptible of appreciation by a scattered audience, individually or in groups, with appropriate receiving apparatus.

广播，与无线通信不同，可以说是在1920年左右出现的。它可以被定义为通过无线电电话系统有计划地传播音乐、讲座、戏剧、幽默、新闻和信息公告、演讲和仪式、图片和其他适合分散观众个人或团体欣赏的内容，需要相应的接收设备。[ Encyclopedia Britannica，1929年]
