The number of radio stations in the united states has grown from 9,379 in 1990 to more than 11,358 today.
The above figures are latest relased figures and true uptil 2016. They also count the number of commercial radio stations and might not include non-commercial stations.
However, the above figures really are impressive since it shows how the Radio Industry has kept on growing despite the massive growth of the Internet in 2,000s and the arrival of smartphones and social media more recently.
It is clear how radio entertainment and news is still quite popular throughout the country.
