Columbia Graphophone
Columbia Graphophone Co. Ltd. was one of the earliest gramophone companies in the United Kingdom. Founded in 1917 as an offshoot of the American Columbia Phonograph Company, it became an independent British-owned company in 1922 in a management buy-out after the parent company went into receivership. In 1925 it acquired a controlling interest in its American parent company to take advantage of a new electrical recording process. The British firm also controlled the US operations from 1925 until 1931. That year Columbia Graphophone in the UK merged with the Gramophone Company (which sold records under the HMV label) to form EMI. At the same time, Columbia divested itself of its American branch, which was eventually absorbed by Columbia Broadcasting System (CBS) in 1938. As Columbia Records, it became a successful British label in the 1950s and 1960s, and was eventually replaced by the newly created EMI Records, as part of a label consolidation. This in turn was absorbed by th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Acoustic Recording
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog signal, analog sound Recording medium, storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital audio, digital media, in the form of the compact disc, had gained a larger market share, and the record left the main ...

Western Electric
The Western Electric Company was an American electrical engineering and manufacturing company officially founded in 1869. A wholly owned subsidiary of American Telephone & Telegraph for most of its lifespan, it served as the primary equipment manufacturer, supplier, and purchasing agent for the Bell System from 1881 to 1984 when it was dismantled. The company was responsible for many technological innovations as well as developments in industrial management. History In 1856, George Shawk, a craftsman and telegraph maker, purchased an electrical engineering business in Cleveland, Ohio. In January, 1869, Shawk had partnered with Enos M. Barton in the former Western Union repair shop of Cleveland, to manufacture burglar, fire alarms, and other electrical items. Both men were former Western Union employees. Shawk, was the Cleveland shop foreman and Barton, was a Rochester, New York telegrapher. During this Shawk and Barton partnership, one customer was an inventor sourcing parts an ...

Radio Set
An antique radio is a radio receiving set that is collectible because of its age and rarity. Types of antique radio Morse receivers The first radio receivers used a coherer and sounding board, and were only able to receive CW continuous wave (CW) transmissions, encoded with Morse code (wireless telegraphy). Later wireless telephony, transmission and reception of speech became possible, although Morse code transmission continued in use until the 1990s. All the following sections concern speech-capable radio, or wireless telephony. Early home-made sets The idea of radio as entertainment took off in 1920, with the opening of the first stations established specifically for broadcast to the public such as KDKA in Pittsburgh and WWJ in Detroit. More stations opened in cities across North America in the following years and radio ownership steadily gained in popularity. Radio sets from before 1920 are rarities, and are probably military artifacts. Sets made prior to approximatel ...

Hotel Astor
Hotel Astor was a hotel on Times Square in the Midtown Manhattan neighborhood of New York City. Built in 1905 and expanded in 1909–1910 for the Astor family, the hotel occupied a site bounded by Broadway, Shubert Alley, and 44th and 45th Streets. Architects Clinton & Russell designed the hotel as a 11-story Beaux-Arts edifice with a mansard roof. It contained 1,000 guest rooms, with two more levels underground for its extensive "backstage" functions, such as the wine cellar. The hotel was developed as a successor to the Waldorf-Astoria. Hotel Astor's success triggered the construction of the nearby Knickerbocker Hotel by other members of the Astor family two years later. The building was razed in 1967 to make way for the high-rise office tower One Astor Plaza. Construction With its elaborately decorated public rooms and its roof garden, the Hotel Astor was perceived as the successor to the Astor family's Waldorf-Astoria on 34th Street. William C. Muschenheim and his br ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Radio 2XG
Radio station 2XG, also known as the "Highbridge Station", was an experimental radio station located in New York City and licensed to the De Forest Radio Telephone and Telegraph Company from 1915–1917 and 1920–1924. In 1916, it became the first radio station employing a vacuum-tube transmitter to make news and entertainment broadcasts on a regular schedule, and, on November 7, 1916, became the first to broadcast U.S. presidential election returns by spoken word instead of by Morse code. Pre-World War I history Initially all radio stations used spark transmitters, which could only transmit Morse code messages. In 1904, Valdemar Poulsen invented an "arc-transmitter" capable of transmitting full audio, and in late 1906 Lee de Forest founded the Radio Telephone Company and began producing his own "sparkless" arc-transmitters. Between 1907 and 1910, de Forest made a number of demonstration entertainment broadcasts, and even spoke about developing news and entertainment broadcasting ...

Vaccuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Audion
The Audion was an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest in 1906.De Forest patented a number of variations of his detector tubes starting in 1906. The patent that most clearly covers the Audion is , Space Telegraphy', filed January 29, 1907, issued February 18, 1908 The link is to a reprint of the paper in the ''Scientific American Supplement'', Nos. 1665 and 1666, November 30, 1907 and December 7, 1907, p.348-350 and 354-356. It was the first triode, consisting of an evacuated glass tube containing three electrodes: a heated filament, a grid, and a plate. It is important in the history of technology because it was the first widely used electronic device which could amplify. A low power signal at the grid could control much more power in the plate circuit. Audions had more residual gas than later vacuum tubes; the residual gas limited the dynamic range and gave the Audion non-linear characteristics and erratic per ...
