News radio stations function as major sources of local news and information for their listeners, but radio stations across the United States are facing unprecedented challenges with constant drops in advertising revenue and decreasing numbers of stations devoted to an all-news or talk format. A national survey of news radio station executives from stations in different-sized markets found that stations in smaller markets were likely to broadcast a greater percentage of locally produced content compared to syndicated or outsourced content than stations in larger markets. Ownership structure, such as whether a smaller station was owned independently or by a large media conglomerate, did not appear to have an effect on the levels of local programming.

在广播中评估本地新闻

新闻广播电台是其听众获取本地新闻和信息的主要来源，但美国各地的广播电台都面临着前所未有的挑战，广告收入不断下降，专门提供全新闻或谈话形式的电台数量也在减少。一项针对来自不同规模市场电台的新闻广播电台高管的全国调查发现，与大型市场电台相比，与辛迪加或外包内容相比，较小市场中的电台播放的本地制作内容的比例可能更高。所有权结构，例如较小的电台是独立拥有还是由大型媒体集团拥有，似乎对本地节目的水平没有影响。
