Tel-musici
The Tel-musici was an early entertainment innovation, which used telephone lines to transmit phonograph recordings to individual households. Subscribers called a central "music room" to request selections, which they listened to at home over specially designed loudspeakers called "magnaphones". The service later incorporated live programs, expanding its operations to more along the lines of a general "telephone newspaper". A Tel-musici company was incorporated in Delaware in 1908, and the service began operation in Wilmington the next year. However, although there were plans to expand throughout the United States, only this single location ever became operational, until it ceased operations around 1914. History The primary individual behind the Tel-musici was inventor George R. Webb. In January 1908, while soliciting for investors, he arranged a demonstration of the concept at a Baltimore hotel, where listeners telephoned a remote location with their requests, which were played ba ...

Telephone Newspaper
Telephone Newspapers, introduced in the 1890s, transmitted news and entertainment to subscribers over telephone lines. They were the first example of electronic broadcasting, although only a few were established, most commonly in European cities. These systems predated the development, in the 1920s, of radio broadcasting. They were eventually supplanted by radio stations, because radio signals could more easily cover much wider areas with higher quality audio, without incurring the costs of a telephone line infrastructure. History The introduction of the telephone in the mid-1870s included numerous demonstrations of its use for transmitting musical concerts over various distances. In one particularly advanced example, Clément Ader prepared a listening room at the 1881 Paris Electrical Exhibition, where attendees could listen to performances, in stereo, from the Paris Grand Opera. The concept also appeared in Edward Bellamy's influential 1888 utopian novel, '' Looking Backwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musolaphone
The Musolaphone (also marketed as the Multa Musola), developed by the Automatic Electric Company of Chicago, Illinois, was an audio distribution system that transmitted news and entertainment over telephone lines to subscribing homes and businesses. The company's "Automatic Enunciator" loudspeakers were employed at the receiving end. A test commercial installation was established in southside Chicago in 1913, but the project was short-lived and did not prove to be financially successful. This was the last significant attempt to set up a "telephone newspaper" to transmit entertainment over telephone lines in the United States, prior to the development of radio broadcasting in the early 1920s. History In 1910, the Automatic Electric Company, an established firm best known for making automatic telephone switchboards, announced its development of a new loudspeaker, called the "Automatic Enunciator", which was envisioned to have multiple potential uses. In part, Joseph Harris, presid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lohengrin (opera)
''Lohengrin'', WWV 75, is a Romantic opera in three acts composed and written by Richard Wagner, first performed in 1850. The story of the eponymous character is taken from medieval German romance, notably the '' Parzival'' of Wolfram von Eschenbach, and its sequel '' Lohengrin'', itself inspired by the epic of '' Garin le Loherain''. It is part of the Knight of the Swan legend. The opera has inspired other works of art. King Ludwig II of Bavaria named his castle Neuschwanstein Castle after the Swan Knight. It was King Ludwig's patronage that later gave Wagner the means and opportunity to complete, build a theatre for, and stage his epic cycle '' Der Ring des Nibelungen''. He had discontinued composing it at the end of Act II of ''Siegfried'', the third of the ''Ring'' tetralogy, to create his radical chromatic masterpiece of the late 1850s, '' Tristan und Isolde'', and his lyrical comic opera of the mid-1860s, ''Die Meistersinger von Nürnberg''.

Telephone Switchboard
A telephone switchboard was a device used to connect circuits of telephones to establish telephone calls between users or other switchboards, throughout the 20th century. The switchboard was an essential component of a manual telephone exchange, and was operated by switchboard operators who used electrical cords or switches to establish the connections. The electromechanical automatic telephone exchange, invented by Almon Strowger in 1888, gradually replaced manual switchboards in central telephone exchanges around the world. In 1919, the Bell System in Canada also adopted automatic switching as its future technology, after years of reliance on manual systems. Nevertheless, many manual branch exchanges remained operational into the second half of the 20th century in many enterprises. Later electronic devices and computer technology gave the operator access to an abundance of features. A private branch exchange (PBX) in a business usually has an attendant console, or an auto-at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Electric Company
Automatic Electric Company (A.E. Co.) was an American telephone equipment supplier primarily for independent telephone companies in North America, but also had a worldwide presence. With its line of automatic telephone exchanges, it was also a long-term supplier of switching equipment to the Bell System, starting in 1919. The company was the largest manufacturing unit of the Automatic Electric Group.GTE Automatic Electric (1955) ''This is Automatic Electric--Pioneers in Communication Techniques'' In 1955, the company was acquired by General Telephone and Electronics (GT&E). After numerous reorganization within GTE, the companies assets it came under the umbrella of Lucent in the 1990s, and subsequently part of Nokia. History In 1889, Almon Strowger, of Kansas City, Missouri, was inspired by the idea of manufacturing automatic telephone exchanges that would not require switchboard operators. He founded the Strowger Automatic Telephone Exchange Company in 1891, which held the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Newspapers
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from el, τῆλε (''tēle'', ''far'') and φωνή (''phōnē'', ''voice''), together meaning ''distant voice''. A common short form of the term is ''phone'', which came into use early in the telephone's history. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a ...

Information By Telephone
Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random, and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form. Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation. Information is often processed iteratively: Data available at one step are processed into information to be interpreted and processed at the next step. For example, in written text each symbol or letter conveys information relevant to the word it is part of, each word conveys information relevant ...

Telecommunications Systems
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded ...

Telephony
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs. Each user had a separate telephone wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
