American radio stations generated a total revenue of almost 15 billion U.S. dollars in 2017, of which 890 million dollars was generated through online radio streaming. In addition to the massive national stations and broadcasts, local public radio stations also appear to be thriving. Public radio station revenue has increased from around 624 million U.S. dollars in 2009 to over 830 million in 2016. ‘Country’ is by far the most popular format, with 2,137 individual stations broadcasting music from this genre. As of 2018, Americans averaged 106 minutes of radio listening time per day, with much of this time being spent while commuting.
The continuous presence of advertising on radio, heard in cars as well as in public areas, is an incentive for many businesses to invest in this medium of advertising. Some of the leading investors in radio advertising are T-Mobile, the Comcast Corporation, Home Depot, and AT&T. In 2017 alone, T-Mobile spent 188 million U.S. dollars on radio advertising, while Comcast splashed out another 185 million.
