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. For years, Arbitron was a part of Control Data Corporation (CDC) and in 1992, it became a part of Ceridian Corporation before the company was split in 2001. The then-current Arbitron was formed from the renaming of the old Cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable People Meter
The Portable People Meter (PPM), also known as the Nielsen Meter, is a system developed by Arbitron (now Nielsen Audio) to measure how many people are exposed to individual Radio broadcasting, radio stations and television stations.

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 station, television and radio broadcasting, radio station offerings, and may also include other types of media such as newspapers and internet content. They can coincide with 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 has measured both television and radio audiences since its acquisition of Arbitron, which was completed in Septemb ...

Internet Radio
Internet radio, also known as online radio, web radio, net radio, streaming radio, e-radio and IP 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audience Measurement
Audience measurement calculates 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. The term is sometimes used with regard to practices that help broadcasters and advertisers determine ''who'' is listening, rather than ''how many'' people are listening. In some parts of the world, the resulting numbers are referred to as audience share; in other places, the broader term market share is used. This broader meaning is also known as audience research. Measurements are broken down by media market, which corresponds to large and small metropolitan areas. Methods Diaries The diary was one of the first methods of recording information. However, this is prone to mistakes, forgetfulness and subjectivity. Data is collected down to the level of listener opinion of individual songs cross-referenced against age, race, and economic status in liste ...

Radio broadcasting is the broadcasting of audio signal, 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 Radio receiver, broadcast radio receiver (''radio''). Stations are often affiliated with a radio network that provides content in a common radio format, either in broadcast syndication or simulcast, or both. The code, encoding of a radio broadcast depends on whether it uses an analog signal, analog or digital signal. Analog radio broadcasts use one of two types of radio wave modulation: amplitude modulation for AM radio, or frequency modulation for FM radio. Newer, digital radio stations transmit in several different digital audio standards, such as DAB (Digital Audio Broadcas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
