从 1 92 0年第一家定时播出节目的广播电台KDKA的成功亮相到 2 0世纪 40年代末 ,广播的发展势不可挡。在报纸与广播之间的大战中 ,借助“一战”中受众对快捷信息的迫切需求 ,广播全面胜出。“二战”后 ,电视的崛起宣告了广播的黄金时代告一段落。在激烈的竞争中 ,大批广播电台倒闭 ,幸存下来的不得不通过专业化、细分化的改革在夹缝中求生存求发展。 2 0世纪七、八十年代以来 ,电视又遇到前所未有的激烈竞争的挑战。

Since the 1970s and 1980s, television has encountered unprecedented challenges of fierce competition.
