Time Spent Listening

	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 ...

	Nielsen Audio 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.

	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.
