AQH Share
AQH Share is a statistic that measures broadcast radio listenership. Definition AQH is an abbreviation for Average Quarter-Hour Persons (AQH Persons), defined by Arbitron (now referred to as Nielsen Audio) as the average number of persons listening to a particular station for at least five minutes during a 15-minute period. Share is the percentage of those listening to radio in an Arbitron "market" (typically a metropolitan area A metropolitan area or metro is a region that consists of a densely populated urban agglomeration and its surrounding territories sharing industries, commercial areas, transport network, infrastructures and housing. A metro area usually com ...) who are listening to a particular radio station. Thus, AQH Share for a given station is mathematically expressed as '' QH Persons listening to station / AQH Persons listening to all market radio stations* 100''. Usage AQH Share is most often used in conjunction with TSL (Time Spent Listening) to measure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Broadcasting
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).

Arbitron
Nielsen Audio (formerly Arbitron) is a consumer research company in the United States that collects listener data on radio broadcasting audiences. It was founded as the American Research Bureau by Jim Seiler in 1949 and became national by merging with Los Angeles-based Coffin, Cooper, and Clay in the early 1950s. The company's initial business was the collection of broadcast television ratings. The company changed its name to Arbitron in the mid‑1960s, the namesake of the Arbitron System, a centralized statistical computer with leased lines to viewers' homes to monitor their activity. Deployed in New York City, it gave instant ratings data on what people were watching. A reporting board lit up to indicate which homes were listening to which broadcasts. On December 18, 2012, The Nielsen Company announced that it would acquire Arbitron, its only competitor, for US$1.26 billion. The acquisition closed on September 30, 2013, and the company was re-branded as Nielsen Audio. As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metropolitan Area
A metropolitan area or metro is a region that consists of a densely populated urban agglomeration and its surrounding territories sharing industries, commercial areas, transport network, infrastructures and housing. A metro area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, as well as even states and nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas typically include satellite cities, towns and intervening rural areas that are socioeconomically tied to the principal cities or urban core, often measured by commuting patterns. Metropolitan areas are sometimes anchored by one central city such as the Paris metropolitan area (Paris) or Mumbai Metropolitan Region (Mumbai). In other cases metropolitan areas contain multiple centers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Spent Listening
Time spent listening (TSL) is one of the measurements surveyed by Nielsen Audio in determining ratings for radio stations in the United States. It is the equivalent of Average Time Exposed (ATE), Daily or Weekly. TSL is defined as the amount of time the average listener surveyed spent listening to each radio station at one time, before changing the station or turning it off. Alternately, it is an estimate of how long the average panelist (listener) was exposed to a particular station or stations for a specific time period. TSL trends are used in conjunction with AQH share AQH Share is a statistic that measures broadcast radio listenership. Definition AQH is an abbreviation for Average Quarter-Hour Persons (AQH Persons), defined by Arbitron (now referred to as Nielsen Audio) as the average number of persons listeni ... ("AQH") to evaluate listenership to a station. In some radio formats, a station with low AQH (number of listeners) but high TSL is considered more attractive to ad ...

Data is obtained through a contract with Arbitron. History The company was founded in 1981 as an alliance of 14 stations to provide access to market data which was previously available only to commercial stations.

In the case of the San Francisco Market, for example, KQED-FM actually ranked 2nd or 3rd in 2005-2006 but was absent from traditional reporting of Arbitron data in publications such as Radio & Records which include only commercial stations.
