1919 in radio details the internationally significant events in radio broadcasting for the year 1919.
Guglielmo Giovanni Maria Marconi, 1st Marquis of Marconi was an Italian inventor, electrical engineer, physicist and politician known for his creation of a practical radio wave–based wireless telegraph system. This led to Marconi being credited as the inventor of radio, and winning the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy". His work laid the foundation for the development of radio, television, and all modern wireless communication systems.
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
A television broadcaster or television network is a telecommunications network for the distribution of television content, where a central operation provides programming to many television stations, pay television providers or, in the United States, multichannel video programming distributors. Until the mid-1980s, broadcast programming on television in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks such as the BBC, CBC, PBS, PTV, NBC or ABC in the US and in Australia evolved from earlier radio networks.
Reginald Aubrey Fessenden was a Canadian-born American inventor who received hundreds of patents in various fields, most notably ones related to radio and sonar.
Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum, in a 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 receivers. Before this, most implementations of electronic communication were 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 early as 1898.
The British Broadcasting Company Limited (BBC) was a short-lived British commercial broadcasting company formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom. Licensed by the British General Post Office, its original office was located on the second floor of Magnet House, the GEC buildings in London and consisted of a room and a small antechamber.
A terrestrial network is a group of radio stations, television stations, or other electronic media outlets, that form an agreement to air, or broadcast, content from a centralized source. For example, ABCTooltip American Broadcasting Company and NBCTooltip National Broadcasting Company (U.S.), CBC/Radio-CanadaTooltip Canadian Broadcasting Corporation (Canada), the BBCTooltip British Broadcasting Corporation (UK), the ABCTooltip Australian Broadcasting Corporation (Australia), ARDTooltip ARD (broadcaster) (Germany), PTVTooltip People's Television Network (Philippines), KBSTooltip Korean Broadcasting System, and NHK (Japan) are TV networks that provide programming for local terrestrial television station affiliates to air using signals that can be picked up by the home television sets of local viewers. Networks generally, but not always, operate on a national scale; that is, they cover an entire country.
It is generally recognized that the first radio transmission was made from a temporary station set up by Guglielmo Marconi in 1895 on the Isle of Wight. This followed on from pioneering work in the field by a number of people including Alessandro Volta, André-Marie Ampère, Georg Ohm, James Clerk Maxwell and Heinrich Rudolf Hertz.
The Marconi Company was a British telecommunications and engineering company founded by Italian inventor Guglielmo Marconi in 1897 which was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies.
Arthur Clifford Michelmore was an English television presenter and producer.
CINW was the final call sign used by an English language AM radio station in Montreal, Canada, which, along with French-language sister station CINF, ceased operations at 7:00 p.m. ET on January 29, 2010. Owned and operated by Corus Quebec, it broadcast on 940 kHz with a full-time power of 50,000 watts as a clear channel, Class A station, using a slightly directional antenna designed to improve reception in downtown Montreal.
KDKA is a Class A, clear channel, AM radio station, owned and operated by Audacy, Inc. and licensed to Pittsburgh, Pennsylvania, United States. Its radio studios are located at the combined Audacy Pittsburgh facility in the Foster Plaza on Holiday Drive in Green Tree, and its transmitter site is at Allison Park. The station's programming is also carried over 93.7 KDKA-FM's HD2 digital subchannel, and is simulcast on FM translator W261AX at 100.1 MHz.
The timeline of radio lists within the history of radio, the technology and events that produced instruments that use radio waves and activities that people undertook. Later, the history is dominated by programming and contents, which is closer to general history.
The year 1927 saw a number of significant happenings in radio broadcasting history.
The year 1936 saw a number of significant events in radio broadcasting.
1922 in radio details the internationally significant events in radio broadcasting for the year 1922.
This is a timeline of the history of the Canadian Broadcasting Corporation.
CNR Radio or CN Radio was the first national radio network in North America. It was developed, owned and operated by the Canadian National Railway between 1923 and 1932 to provide en route entertainment and information for its train passengers. As broadcasts could be received by anyone living in the coverage area of station transmitters, the network provided radio programming to Canadians from the Pacific coast to the Atlantic coast.
Radio was introduced in Canada in the late 1890s, although initially transmissions were limited to the dot-and-dashes of Morse code, and primarily used for point-to-point services, especially for maritime communication. The history of broadcasting in Canada dates to the early 1920s, as part of the worldwide development of radio stations sending information and entertainment programming to the general public. Television was introduced in the 1950s, and soon became the primary broadcasting service.
