Television network

A television network is a telecommunications network for distribution of television program content, whereby a central operation provides programming to many television stations or pay television providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (such as the BBC, NBC or CBC) evolved from earlier radio networks.

Overview

In countries where most networks broadcast identical, centrally originated content to all of their stations and where most individual television transmitters therefore operate only as large "repeater stations", the terms "television network", "television channel" (a numeric identifier or radio frequency) and "television station" have become mostly interchangeable in everyday language, with professionals in television-related occupations continuing to make a differentiation between them. Within the industry, a tiering is sometimes created among groups of networks based on whether their programming is simultaneously originated from a central point, and whether the network master control has the technical and administrative capability to take over the programming of their affiliates in real-time when it deems this necessary – the most common example being during national breaking news events.

American Broadcasting Company

The American Broadcasting Company (ABC) (stylized in its logo as abc since 1957) is an American commercial broadcast television network that is owned by the Disney–ABC Television Group, a subsidiary of Disney Media Networks division of The Walt Disney Company. The network is part of the Big Three television networks. The network is headquartered on Columbus Avenue and West 66th Street in Manhattan, with additional major offices and production facilities in New York City, Los Angeles and Burbank, California.

Since 2007, when ABC Radio (also known as Cumulus Media Networks) was sold to Citadel Broadcasting, ABC has reduced its broadcasting operations almost exclusively to television. The fifth-oldest major broadcasting network in the world, ABC is often nicknamed as "the Alphabet Network", as its initialism also represent the first three letters of the English alphabet.

ABC originally launched on October 12, 1943 as a radio network, separated from and serving as the successor to the NBC Blue Network, which had been purchased by Edward J. Noble. It extended its operations to television in 1948, following in the footsteps of established broadcast networks CBS and NBC. In the mid-1950s, ABC merged with United Paramount Theatres, a chain of movie theaters that formerly operated as a subsidiary of Paramount Pictures. Leonard Goldenson, who had been the head of UPT, made the new television network profitable by helping develop and greenlight many successful series. In the 1980s, after purchasing an 80% interest in cable sports channel ESPN, the network's parent merged with Capital Cities Communications, owner of several print publications, and television and radio stations. In 1996, most of Capital Cities/ABC's assets were purchased by The Walt Disney Company.

ABC Television

ABC Television is a service of the Australian Broadcasting Corporation launched in 1956. As a public service broadcaster, the ABC provides four non-commercial channels within Australia, and a partially advertising-funded satellite channel overseas. ABC is one of five main free-to-air networks in Australia.

History

The history of the ABC's television operations can be traced back to 1953, when the federal Television Act was passed, providing the initial regulatory framework for both the ABC and commercial television networks. Over the next three years, planning for the introduction of a national television service was put in place—land for studios and transmitters in Sydney and Melbourne was acquired, and overseas tutors were brought to Australia to assist with training.

Commercial station TCN-9 Sydney was the first to broadcast in Australia, soon followed by the ABC's own ABN-2 Sydney and later ABV-2 in Melbourne. Six stations, three in Melbourne and three in Sydney, were in operation in time to cover the 1956 Summer Olympics in Melbourne. The ABC's first television broadcast was inaugurated by Prime Minister Robert Menzies on 5 November, at the Gore Hill studios in Sydney, followed two weeks later by transmission in Melbourne.Outside broadcasting was also initiated on 5 November, from the ABC's first outside broadcast van. The van, now in the collection of the National Museum of Australia, was instrumental in the production of thousands of outside broadcasts. It was restored in time to be displayed at the Sydney Olympic Games and was used to film the visit of Queen Elizabeth II to the site of the National Museum in 2000.

Form of the Good

Plato describes "The Form of the Good", or more literally "the idea of the good" (ἡ τοῦ ἀγαθοῦ ἰδέα), in his dialogue the Republic (508e2–3), speaking through the character of Socrates. Plato introduces several forms in his works, but identifies the Form of the Good as the superlative. This form is the one that allows a philosopher-in-training to advance to a philosopher-king. It cannot be clearly seen or explained, but once it is recognized, it is the form that allows one to realize all the other forms.

Usages in The Republic

The first references we see in The Republic to the Form of the Good can be found within the conversation between Glaucon and Socrates (454 c–d). When trying to answer such difficult questions pertaining to the definition of justice, Plato identifies that we should not “introduce every form of difference and sameness in nature” instead we must focus “on the one form of sameness and difference that was relevant to the particular ways of life themselves” which is the Form of the Good. This Form is the basis for understanding all other Forms, it is what allows us to understand everything else. Through the conversation between Socrates and Glaucon (508 a–c) Plato analogizes the Form of the Good with the sun as it is what allows us to see things. Here, Plato describes how the sun allows for sight. But he makes a very important distinction, “sun is not sight” but it is “the cause of sight itself.” As the sun is in the visible realm, the Form of Good is in the intelligible realm. It is “what gives truth to the things known and the power to know to the knower”. It is not only the “cause of knowledge and truth, it is also an object of knowledge”.
