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] |
Portable People Meter
The Portable People Meter (PPM), also known as the Nielsen Meter, was a system developed by Arbitron (now Nielsen Audio) to measure how many people are exposed or listening to individual radio stations and television stations, including cable television. The PPM is worn like a pager, and detects hidden audio tones within a station or network's audio stream, logging each time it finds such a signal. There are several parts to the PPM system: *An encoder that inserts the tones subliminally into a station's or broadcast network's airchain via psychoacoustic masking; *A monitor that checks that the encoder is working properly; *The wearable Portable People Meter carried by each panelist; *A base station for each PPM, where each panelist in the household places it overnight to recharge the battery; and *A portable recharger for vacations and other trips away from the home base. The original PPM concept required the base station to be connected to a telephone line to transmit pane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Market
A media market, broadcast market, media region, designated market area (DMA), television market area, or simply market is a region where the population can receive the same (or similar) television and radio station offerings, and may also include other types of media such as newspapers and internet content. They can coincide or overlap with one or more metropolitan areas, though rural regions with few significant population centers can also be designated as markets. Conversely, very large metropolitan areas can sometimes be subdivided into multiple segments. Market regions may overlap, meaning that people residing on the edge of one media market may be able to receive content from other nearby markets. They are widely used in audience measurements, which are compiled in the United States by Nielsen Media Research. Nielsen measures both television and radio audiences since its acquisition of Arbitron, which was completed in September 2013. Markets are identified by the largest ...

Internet Radio
Online radio (also web radio, net radio, streaming radio, e-radio, IP radio, Internet radio) is a digital audio service transmitted via the Internet. Broadcasting on the Internet is usually referred to as webcasting since it is not transmitted broadly through wireless means. It can either be used as a stand-alone device running through the Internet, or as a software running through a single computer. Internet radio is generally used to communicate and easily spread messages through the form of talk. It is distributed through a wireless communication network connected to a switch packet network (the internet) via a disclosed source. Internet radio involves streaming media, presenting listeners with a continuous stream of audio that typically cannot be paused or replayed, much like traditional broadcast media; in this respect, it is distinct from on-demand file serving. Internet radio is also distinct from podcasting, which involves downloading rather than streaming. Internet ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Audience Measurement
Audience measurement measures how many people are in an audience, usually in relation to radio listenership and television viewership, but also in relation to newspaper and magazine readership and, increasingly, web traffic on websites. Sometimes, the term is used as pertaining to practices which help broadcasters and advertisers determine ''who'' is listening rather than just ''how many'' people are listening. In some parts of the world, the resulting relative numbers are referred to as audience share, while in other places the broader term market share is used. This broader meaning is also called audience research. Measurements are broken down by media market, which for the most part corresponds to metropolitan areas, both large and small. Methods Diaries The diary was one of the first methods of recording information. However, this is prone to mistakes and forgetfulness, as well as subjectivity. Data is also collected down to the level of listener opinion of individ ... [...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). Television broadcasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Columbia, Maryland
Columbia is a census-designated place in Howard County, Maryland. It is one of the principal communities of the Baltimore–Washington metropolitan area. It is a planned community consisting of 10 self-contained villages. Columbia began with the idea that a city could enhance its residents' quality of life. Creator and developer James W. Rouse saw the new community in terms of human values, rather than merely economics and engineering. Opened in 1967, Columbia was intended to not only eliminate the inconveniences of then-current subdivision design, but also eliminate racial, religious and class segregation. Columbia proper consists only of that territory governed by the Columbia Association, but larger areas are included under its name by the U.S. Postal Service and the Census Bureau. These include several other communities which predate Columbia, including Simpsonville, Atholton, and in the case of the census, part of Clarksville. The census-designated place had a popula ...
