Traffic (broadcasting)
{{for, broadcasting about traffic conditions, traffic reporting In broadcasting, traffic is the scheduling of program material, and in particular the advertisements, for the broadcast day. In a commercial radio or TV station there is a vital link between sales (of advertisement or commercial space) and traffic in keeping the information about commercial time availability. The station sells airtime to its customers. It is not unusual in a single hour for 18–20 minutes to be commercials. The traffic department together with sales aims to sell the available airtime ("avails") at the best possible rates. The traffic department generates a daily log of programming elements such as commercials, features and public service announcement A public service announcement (PSA) is a message in the public interest disseminated by the media without charge to raise public awareness and change behavior.

Broadcasting
Broadcasting is the distribution (business), distribution of sound, audio or video content to a dispersed audience via any electronic medium (communication), mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Service Announcement
A public service announcement (PSA) is a message in the public interest disseminated by the media without charge to raise public awareness and change behavior. In the UK, they are generally called a public information film (PIF); in Hong Kong, they are known as an announcement in the public interest (API). History The earliest public service announcements (in the form of moving pictures) were made before and during the Second World War years in both the UK and the US. In the UK, amateur actor Richard Massingham set up Public Relationship Films Ltd in 1938 as a specialist agency for producing short educational films for the public. In the films, he typically played a bumbling character who was slightly more stupid than average and often explained the message of the film by demonstrating the risks if it was ignored. The films covered topics such as how to cross the road, how to prevent the spread of diseases, how to swim, and how to drive without causing the road to be unsafe for ...

Dayparting
In broadcast programming, dayparting is the practice of dividing the broadcast day into several parts, in which a different type of radio programming or television show appropriate for that time period is aired. Television programs are most often geared toward a particular demography, and what the target audience typically engages in at that time. North America On radio Nielsen Audio (known as Arbitron until it merged with Nielsen Holdings in 2013), the leading audience measurement service in the United States, divides a weekday into five dayparts: morning drive time (6:00–10:00 a.m.), midday (10:00 a.m.–3:00 p.m.), afternoon drive (3:00–7:00 p.m.), evenings (7:00 p.m.–midnight) and overnight (midnight–6:00 a.m.). In radio broadcasting through most of the 1990s, dayparting was also used for censorship purposes. Many songs that were deemed unsuitable for young listeners were played only during the late evening or overnight hours, when chi ...

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).
