NPR’s flagship programs, All Things Considered and Morning Edition, reached their largest weekly audience ever, at 14.4 million and 14.65 million listeners, respectively continuing to be two of the largest news radio programs in the country, and larger than many well-known television news programs.
Hannity has over 15 million and Limbaugh over 20 million,
The following is a link to the audience estimates for the commercial talk show hosts. http://www.talkers.com/top-talk-audiences/ Rush clocks in at 14 million, not 20. Sean 13.5. The source is an advocate for talk radio. They take the Nielson audience reports and create as best they can the total weekly listeners of each host. There are certain markets where the audience is too small to measure and yet Rush and Sean are carried in those markets. Same hold true for NPR. My NPR station is carried in 6 non rated markets on translators. None of those listeners are counted as part of the NPR audience.
