History Of Columbia Broadcasting Company (CBS)

CBS, CBS or amateurs was established in 1927 as a radio network under the name "Joint Independent Broadcasting Corporation" as a radio broadcasting network. In 1928 the name was changed to CBS. In the same year, William Paley, the big son of cigar making, took over CBS with his father's financial support. Paley acquired CBS for $ 400,000 and inherited the network of 22 branches and 16 employees. He knows little about the technical knowledge of the radio, but he believes he can only attract advertisers if he can attract a large audience.

Until the fall of 1948, four networks were regularly scheduled - the American Broadcasting Corporation (ABC), the Columbia Broadcasting System (CBS), the National Broadcasting Corporation (NBS), the National Broadcasting Corporation (NBC), and folded in 1955 Dumont TV network - very rare. On some nights, the network may not provide programs at all and few networks broadcast full programs throughout the whole period (ie Eastern Standard Time from 8 PM to 11 PM). Because sales of television are very low, even if there are programs, their potential viewers are limited. In order to promote sales, daytime sports broadcasts were arranged to attract buyers to buy suit at local appliances stores and pubs on weekends.

The American radio was immediately included in the oligopoly of the large network. By the mid-1940's, the broadcasting industry was established by four networks: National Broadcasting Corporation (NBC), Columbia Broadcasting System (CBS), Common Broadcasting System (MBS) and ABC (ABC, formerly NBC's "Blue Network") It was dominated. Until 1943) Whenever questions are cast on the social mission of public broadcasting systems in other countries like the British Broadcaster Association (BBC), the American model will be a warning story about what the American model should not do.

Let's take a look at the history of television and video technology. In the late 1940s / early 1950s, a broadcasting TV network appeared. In the early days, these companies (NBC, CBS, etc.) sent a central signal to neighboring cities such as New York to Philadelphia and then sent to other places such as Detroit, Chicago, so "chain network" It was called. (First, use the chain's physical coaxial cable, then use a dedicated microwave link). The television network is an early example of a centralized content delivery platform. This tree structure begins with the middle trunk. The central trunk functions like a local station and leaves each receiver. This is not an unfamiliar network structure; when we use CDN we see it on airline schedules and Internet streaming and broadcasting.
