美國大部分的廣播臺和電視臺都是商業性質的，也就是說，他們通過播放節目或廣告賺錢。私人公司從這些商業臺購買廣播或電視的時段給他們的產品做廣告。有線電視臺也屬于商業臺，雖然他們并不經常播放廣告。為了收看有線電視，人們必須每個月都向有線電視公司交納一些錢。
不同的是，公共廣播臺和電視臺不播廣告，人們無須付費就能觀看。這些廣播電視臺的資金來源是政府，或是私人企業，又或者是他們節目的一部分聽眾或觀眾。聯邦政府和一些大機構會向公共廣播電視臺提供補貼和大量財物。小型的商業機構或個人也向當地的公共廣播和電視臺捐款。
美國廣播公司、哥倫比亞廣播公司和全國廣播公司是美國的3大主要的商業廣播和電視網。大多數地區性的商業廣播電視臺都是從這3大全國性的電視網絡接收節目。例如，每個電視網都有一檔晚間新聞節目，地方臺在播放本地新聞之外也會加播這檔節目。 |
