Old-time Radio
The Golden Age of Radio, also known as the old-time radio (OTR) era, was an era of radio in the United States where it was the dominant electronic home entertainment medium. It began with the birth of commercial radio broadcasting in the early 1920s and lasted through the 1950s, when television superseded radio as the medium of choice for scripted programming, variety and dramatic shows. Radio was the first broadcast medium, and during this period people regularly tuned in to their favorite radio programs, and families gathered to listen to the home radio in the evening. According to a 1947 C. E. Hooper survey, 82 out of 100 Americans were found to be radio listeners. A variety of new entertainment formats and genres were created for the new medium, many of which later migrated to television: radio plays, mystery serials, soap operas, quiz shows, talent shows, daytime and evening variety hours, situation comedies, play-by-play sports, children's shows, cooking show ...

Girl Listening To Radio
A girl is a young female human, usually a child or an adolescent. While the term ''girl'' has other meanings, including ''young woman'',Dictionary.com, "Girl"'' Retrieved January 2, 2008. ''daughter'' or ''girlfriend'' regardless of age, the first meaning is the most common one. The treatment and status of girls in any society is usually closely related to the status of women in that culture. In cultures where women have or had a low social position, girls may be unwanted by their parents, and society may invest less in girls. The difference in girls' and boys' upbringing ranges from slight to completely different. Mixing of the sexes may vary by age, and from totally mixed to total sex segregation. Etymology The English word ''girl'' first appeared during the Middle Ages between 1250 and 1300 CE and came from the Anglo-Saxon word ' (also spelled ' or '). The Anglo-Saxon word ' meaning ''dress'' or ''clothing item'' also seems to have been used as a metonym in some s ...

Radio
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for 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 ob ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Westinghouse Electric (1886)
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse and headquartered in Pittsburgh, Pennsylvania. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. Through the early and mid-20th century, Westinghouse Electric was a powerhouse in heavy industry, electrical production and distribution, consumer electronics, home appliances and a wide variety of other products. They were a major supplier of generators and steam turbines for most of their history, and was also a major player in the field of nuclear power, starting with the Westinghouse Atom Smasher in 1937. A series of downturns and management missteps in the 1970s and 80s combined with large cash balances led the company to enter the financial services business. Their focus was on mortgages, which suffered significant losses in the late 1980s. In 1992 they announced a major restruct ...

Reginald Fessenden
Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-American electrical engineer and inventor who received hundreds of List of Reginald Fessenden patents, patents in fields related to radio and sonar between 1891 and 1936 (seven of them after his death). Fessenden pioneered developments in radio technology, including the foundations of amplitude modulation (AM) radio. His achievements included the first transmission of speech by radio (1900), and the first two-way radiotelegraphic communication across the Atlantic Ocean (1906). In 1932 he reported that, in late 1906, he also made the first radio broadcast of entertainment and music, although that claim has not been well documented. He did a majority of his work in the United States and, in addition to his Canadian citizenship, claimed U.S. citizenship through his American-born father. Early years Reginald Fessenden was born October 6, 1866, in East Bolton, Quebec, East Bolton, Canada East, the eldest of ...

Christmas Eve
Christmas Eve is the evening or entire day before Christmas, the festival commemorating nativity of Jesus, the birth of Jesus in Christianity, Jesus. Christmas Day is observance of Christmas by country, observed around the world, and Christmas Eve is widely observed as a full or partial holiday in anticipation of Christmas Day. Together, both days are considered one of the most culturally significant celebrations in Christendom and Western world, Western society. Christmas celebrations in the Christian denomination, denominations of Western Christianity have long begun on Christmas Eve, due in part to the Christian liturgical day starting at sunset, a practice inherited from Jewish tradition, and based on the Genesis creation narrative, story of Creation in the Book of Genesis: "And there was evening, and there was morning—the first day." Many churches still ring their church bells and hold Christian prayer, prayers in the evening; for example, the Nordic Lutheran churches. ...

AM Broadcasting
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the " Golden Age of Radio", until television broadcasting became widespread in the 1950s and received much of the programming previously carried by radio. Later, AM radio's audiences declined greatly due to competition from FM (frequency modulation) radio, Digital Audio Broadcasting (DAB), satellite radio, HD (digital) radio, Internet radio, music streaming services, and podca ...

Amplitude Modulation
Amplitude modulation (AM) is a signal modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the instantaneous amplitude of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in which either the frequency of the carrier wave is varied, as in frequency modulation, or its Phase (waves), phase, as in phase modulation. AM was the earliest modulation method used for transmitting audio in radio broadcasting. It was developed during the first quarter of the 20th century beginning with Roberto Landell de Moura and Reginald Fessenden's radiotelephone experiments in 1900. This original form of AM is sometimes called double-sideband amplitude modulation (DSBAM), because the standard method produces sidebands on either side of the carrier frequency. Single-sideband modulation uses bandpass filters to eliminate one of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Théâtrophone
Théâtrophone (, "the theatre phone") was a telephony, telephonic distribution system available in portions of Europe that allowed the subscribers to listen to opera and theatre performances over the telephone lines. The théâtrophone evolved from a Clément Ader invention, which was first demonstrated in 1881, in Paris. Subsequently, in 1890, the invention was commercialized by Compagnie du Théâtrophone, which continued to operate until 1932. Origin The origin of the théâtrophone can be traced to a telephonic transmission system demonstrated by Clément Ader at the 1881 International Exposition of Electricity in Paris. The system was inaugurated by the French President Jules Grévy, and allowed broadcasting of concerts or plays. Ader had arranged 80 telephone transmitters across the front of a stage to create a form of Binaural recording, binaural stereophonic sound. It was the first two-channel audio system, and consisted of a series of telephone transmitters connected fr ...

Morse Code
Morse code is a telecommunications method which Character encoding, encodes Written language, text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy. International Morse code encodes the 26 ISO basic Latin alphabet, basic Latin letters to , one Diacritic, accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals (Prosigns for Morse code, prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration can vary for signal clarity and operator skill, but for any one message, once the rhythm is established, a beat (music), half-beat is the basic unit of time measurement in Morse code. The duration of a ''dah'' is three times the duration ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
