Radio formatA radio format, programming format (not to be confused with broadcast programming), or specialist station (British English) describes the overall content broadcast on a radio station. The radio format emerged mainly in the United States in the 1950s, at a time when radio was compelled to develop new and exclusive ways to programming by competition with television. The formula has since spread as a reference for commercial radio programming worldwide.
Flagship (broadcasting)In broadcasting, a flagship (also known as a flagship station or key station) is the broadcast station which originates a television network, or a particular radio or television program that plays a key role in the branding of and consumer loyalty to a network or station. This includes both direct network feeds and broadcast syndication, but generally not backhauls.
Clear-channel stationA clear-channel station is a North American AM radio station that has the highest level of protection from interference from other stations, particularly from nighttime skywave signals. This classification exists to ensure the viability of cross-country or cross-continent radio service enforced through a series of treaties and statutory laws.Talk radioTalk radio is a radio format containing discussion about topical issues and consisting entirely or almost entirely of original spoken word content rather than outside music. They may feature monologues, dialogues between the hosts, interviews with guests, and/or listener participation which may be live conversations between the host and listeners who "call in" (usually via telephone) or via voice mail.

Radio broadcastingRadio broadcasting is the transmission of signals, especially audio, to receivers using radio waves over a wide area. Listeners require a broadcast radio receiver to receive these signals. "Terrestrial" broadcasts come from stations on land, and include AM and FM (both analog); and DAB (digital). Audio is also broadcast via satellite in both digital and analog, originating from a satellite in orbit around Earth.List of North American broadcast station classesThis is a list of broadcast station classes applicable in much of North America under international agreements between the United States, Canada, and Mexico. Effective radiated power (ERP) and height above average terrain (HAAT) are listed unless otherwise noted. All radio and television stations within 320 kilometers (199 miles) of the US-Canada or US-Mexico border must get approval by both the domestic and foreign agency.
SimulcastBroadcasting the same content over multiple mediums Simulcast (a portmanteau of "simultaneous broadcast") is the broadcasting of programs or events across more than one resolution, bitrate or medium, or more than one service on the same medium, at exactly the same time (that is, simultaneously). For example, BBC Radio 4 is simulcast on both FM and DAB. Likewise, the BBC's Prom concerts were formerly simulcast on both BBC Radio 3 and BBC Television.
HertzThe hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the reciprocal of one second. It is used only in the case of periodic events.
Commercial broadcastingCommercial broadcasting (also called private broadcasting) is the broadcasting of television programs and radio programming by privately owned corporate media, as opposed to state sponsorship, for example.
WattThe watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m⋅s. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottishinventor, mechanical engineer, and chemist who in 1776 improved the Newcomen engine with his own steam engine, which became fundamental for the Industrial Revolution.*As an Amazon Associate I earn from qualifying purchases.
