List of most-listened-to radio programs
In the United States radio listenership is gauged by Arbitron and others for both commercial radio and public radio. Arbitron and similar services provide estimates by regional market and by standard daypart, but does not compile nationwide information by host. Because there are significant gaps in Arbitron's coverage in rural areas, and because there are only a few markets where Arbitron's proprietary data can be compared against competing ratings measurers, there is a great deal of estimation and interpolation when attempting to compile a list of the most-listened-to radio programs in the United States.
Talkers Magazine, a trade publication focusing on talk radio, compiles a list of the most-listened-to commercial long-form talk shows in the United States, based primarily on Arbitron data and estimated to the nearest 250,000 listeners. In addition to Talkers' independent analyses, radio companies of all formats include estimates of audience in news releases. The nature of news releases allows radio companies to inflate their listener totals by obscuring the difference between listeners at any given time, cumulative listenership over a time frame, and potential audience.
The total listenership for terrestrial radio in the year 2005 was 230 million. Sirius XM Radio has a base of 18.5 million subscribers as of 2009[update]. American Top 40 attracts over 20 million listeners per week. Rush Limbaugh's show has been the number one commercial talk show since at least 1991 when record keeping began. NPR's Morning Edition and All Things Considered are the two most popular news programs.
Until the development of portable people meters, Arbitron did not have the capability to measure individual airings of a program the way Nielsen Ratings can for television, and as such, it only measures in three-month moving averages each month. Portable people meters are currently only available in the largest markets Arbitron serves. Thus, it is impossible under current survey techniques to determine the listenership of an individual event such as the Super Bowl.
Popular radio shows in the United States 
Talkers Magazine compiles Arbitron's data, along with other sources, to estimate the minimum weekly audiences of various commercial long-form talk radio shows. NPR and APM compile Arbitron's data for its public radio shows and releases analysis through press releases.
|The Rush Limbaugh Show||Conservative talk||Midday||14+|
|The Sean Hannity Show||Conservative talk||East Coast PM Drive||13.25+|
|Morning Edition||Public news||AM Drive||12.3|
|All Things Considered||Public news/talk||PM Drive||11.8|
|Marketplace||Public news||PM Drive||9+|
|The Dave Ramsey Show||Financial talk||Midday||7.75+|
|Glenn Beck Program||Conservative talk||West Coast AM Drive||7.5+|
|The Mark Levin Show||Conservative talk||West Coast PM Drive||7.5+|
|Fresh Air||Public news/talk||Midday||4.5|
|A Prairie Home Companion||Public old-time radio||Weekends||4+|
|Coast to Coast AM||Paranormal talk||Overnights||3.5+|
|Talk of the Nation||Public talk||Midday||3.2|
|Wait Wait... Don't Tell Me!||Public panel game show||Weekends||3.2|
|After MidNite with Blair Garner||Country music||Overnights||2.7|
|The Lia Show||Country music||Evenings||2+|
Note on dayparts: because of the effects of time on North American broadcasting, nationally syndicated shows that air live will end up on different dayparts in different time zones. The above list makes note of this. Note that although shows such as Beck's and Levin's are listed under "West Coast" drive times, that their shows are based on the East Coast (and thus air in early midday and early evening time slots there). Their dayparts are indicated as such for the purposes of clarity and consistency.
The list is heavily skewed toward conservative talk radio and public radio due to the greater availability of data for those formats; other formats, particularly those for music, are not measured in as much detail, in part due to irregularities in scheduling.
Sirius XM Radio was monitored directly by Arbitron from 2007 to early 2008. The latest numbers available, from early 2008 (prior to when XM and Sirius merged), have The Howard Stern Show being the most listened-to show on either platform, with Stern's Howard 100 channel netting a "cume" of 1.2 million listeners and Howard 101 (the secondary and replay channel) netting an additional 500,000 listeners. Eastlan Ratings, a service that competes with Arbitron in several markets, includes satellite radio channels in its local ratings; Howard 100 has registered above several lower-end local stations in the markets Eastlan serves, the only satellite station to do so.
The highest rated local talk program in the United States is John and Ken in Los Angeles. Talkers estimates their audience at 1 million listeners.
Because of the large advantage the English language has in the United States, virtually all of the most-listened-to radio programs in the United States are in English. The only other language with an audience large enough to establish national networks is Spanish, and data for shows in that language are much more limited. Other languages (Chinese, Korean, various languages of India, and French) are broadcast only on a local level and thus would be unable to achieve the reach necessary to appear on these lists.
Past top programs in the United States 
From 1933 to 1935, Maxwell House Show Boat was the top radio show in the United States. In 1948 Walter Winchell had the top rated radio show when he surpassed The Fred Allen Show and The Jack Benny Program.
- Jack Benny Program (CBS)
- Amos 'n' Andy (CBS)
- People Are Funny (NBC)
- Our Miss Brooks (CBS)
- Lux Radio Theater (NBC)
- My Little Margie (CBS)

- FBI in Peace and War (CBS)
- Bergen and McCarthy (CBS)
- Groucho Marx's You Bet Your Life (NBC)
Before moving to satellite radio in 2006, The Howard Stern Show peaked at 20 million listeners on syndicated terrestrial radio. At the time of both shows' departure from Talk Radio Network in fall 2012, The Savage Nation was estimated to have an audience of 9 million listeners and The Laura Ingraham Show was estimated at 6 million listeners. The later revivals of both of those shows were much smaller, each only registering an estimated 3 million listeners as of April 2013. Prior to his retirement, Neal Boortz registered approximately 5.75 million listeners. The public radio series Car Talk with Click and Clack had approximately 4 million listeners immediately prior to ending its original run, ranking it among the most-listened-to weekend radio programs in the United States.
Current top stations in the United Kingdom 
Total listenership in the United Kingdom in December 2010 was 46.73 million, all BBC programming had 34.51 million listeners, and all commercial programming had 33.06 million listeners. The figures counted listeners over the age of 15 who tuned in for at least five minutes.
