WRNY (New York City)
WRNY was a New York City AM radio station that began operating in 1925. It was started by Hugo Gernsback's Experimenter Publishing Company to promote his radio and science magazines. Starting in August 1928, WRNY was one of the first stations to make regularly scheduled experimental television broadcasts. Experimenter Publishing went bankrupt in early 1929 and the station was purchased by the Curtiss Aeroplane and Motor Company to promote aviation. WRNY was deleted in 1934, as part of a consolidation on its shared frequency by surviving station WHN (now WEPN). History Origin Hugo Gernsback was born in Luxembourg and studied electrical engineering in Germany. In 1904 at age 20, Gernsback emigrated to the United States to sell his automotive battery design and to start a mail order radio and electrical components business. The Electro Importing Company catalog soon grew into a magazine, ''Modern Electrics''. The Experimenter Publishing Company was started in 1915 and by the ...

Federal Radio Commission
The Federal Radio Commission (FRC) was a government agency that regulated United States radio communication from its creation in 1927 until 1934, when it was succeeded by the Federal Communications Commission (FCC). The FRC was established by the Radio Act of 1927, which replaced the Radio Act of 1912 after the earlier law was found to lack sufficient oversight provisions, especially for regulating broadcasting stations. In addition to increased regulatory powers, the FRC introduced the standard that, in order to receive a license, a radio station had to be shown to be "in the public interest, convenience, or necessity". Previous regulation Radio Act of 1912 Although radio communication (originally known as "wireless telegraphy") was developed in the late 1890s, it was largely unregulated in the United States until the passage of the Radio Act of 1912. This law set up procedures for the Department of Commerce to license radio transmitters, which initially consisted primarily of ...

W3XK
W3XK is widely regarded as the oldest television station in the United States. It was operated by Charles Jenkins of Charles Jenkins Laboratories from July 2, 1928 to 1934. It is believed to be the first station to broadcast to the general public. (Note, however, that in January 1928, GE began broadcasting as 2XB – later W2XB – on 790 kHz using a 24 line mechanical standard. ) The station's frequency started out at 1605 kc., but moved to 6420 kc. (6.42 Mc.), and eventually moved to the 2.-2.1 Mc. band. It broadcast from Wheaton, Maryland (just outside Washington, D.C.), at a resolution of just 48 lines. The way to view television at the time was by mechanical television sets, and this station operated in that way. See also * Bernard H.

Philo Farnsworth
Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor and television pioneer. He made many crucial contributions to the early development of all-electronic television. He is best known for his 1927 invention of the first fully functional all-electronic image pickup device (video camera tube), the image dissector, as well as the first fully functional and complete all-electronic television system.Burns, R. W. (1998), ''Television: An international history of the formative years''. IET History of Technology Series, 22. LondonThe Institution of Engineering and Technology (IET) p. 370. . Farnsworth developed a television system complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth–Hirsch fusor, employing inertial electrostatic confinement (IEC). Like many fusi ...

Mechanical Television
Mechanical television or mechanical scan television is a television system that relies on a mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) are now used to create and display television pictures. Mechanical-scanning methods were used in the earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. However the technology never produced images of sufficient quality to become ...

Radio News Nov 1928 Cover
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortwave
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines (line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave broadcasts of radio programs played an important role in the early days of radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metro-Goldwyn-Mayer
Metro-Goldwyn-Mayer Studios Inc., also known as Metro-Goldwyn-Mayer Pictures and abbreviated as MGM, is an American film, television production, distribution and media company owned by amazon (company), Amazon through MGM Holdings, founded on April 17, 1924 and based in Beverly Hills, California. MGM was formed by Marcus Loew by combining Metro Pictures, Goldwyn Pictures, and Louis B. Mayer Productions, Louis B. Mayer Pictures into one company. It hired a number of well known actors as contract players—its slogan was "more stars than there are in heaven"—and soon became Hollywood's most prestigious film studio, producing popular musical films and winning many Academy Awards. MGM also owned film studios, movie lots, movie theaters and technical production facilities. Its most prosperous era, from 1926 to 1959, was bracketed by two productions of ''Ben-Hur (1959 film), Ben Hur''. After that, it divested itself of the Loews movie theater chain, and, in the 1960s, diversified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amelia Earhart
Amelia Mary Earhart ( , born July 24, 1897; disappeared July 2, 1937; declared dead January 5, 1939) was an American aviation pioneer and writer. Earhart was the first female aviator to fly solo across the Atlantic Ocean. She set many other records, was one of the first aviators to promote commercial air travel, wrote best-selling books about her flying experiences, and was instrumental in the formation of The Ninety-Nines, an organization for female pilots. Born and raised in Atchison, Kansas, and later in Des Moines, Iowa, Earhart developed a passion for adventure at a young age, steadily gaining flying experience from her twenties. In 1928, Earhart became the first female passenger to cross the Atlantic by airplane (accompanying pilot Wilmer Stultz), for which she achieved celebrity status. In 1932, piloting a Lockheed Vega 5B, Earhart made a nonstop solo transatlantic flight, becoming the first woman to achieve such a feat. She received the United States Distinguish ...
