按照傳播方式的不同，廣播可以分為有線廣播和無線廣播。有線廣播是通過導線或者光導纖維所組成的有線傳輸分配網路，將廣播節目信號直接傳遞給用戶接收設備的區域性廣播。無線廣播是通過無線電波傳送節目的廣播形式。有線廣播主要在農村和中小城鎮，傳播範圍有限。目前用作廣告媒體的廣播主要是無線廣播。

按照調製方式的不同，廣播可以分為調頻廣播和調幅廣播。按照使用的波長可以分為長波廣播、中波廣播、短波廣播、超短波廣播等。

Cable broadcasting is a regional broadcasting in which a cable transmission and distribution network composed of wires or optical fibers directly transmits broadcast program signals to user receiving equipment. Wireless broadcasting is a form of broadcasting that transmits programs through radio waves. Cable broadcasting is mainly in rural areas and small and medium-sized cities and towns, with limited spread. Currently, broadcasts used as advertising media are mainly wireless broadcasts.
