Broadcasting
Broadcasting is a one-to-many model. Broadcasting began with one-to-one, with the message covered for a single recipient. The term broadcasting evolved from its usage as the agricultural method of sowing seeds in a field by casting them generally about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to corporation listeners appeared as early as 1898.
Over the air broadcasting is commonly associated with radio as well as television, though more recently, both radio & television transmissions hit begun to be distributed by cable cable television. The receiving parties may include the general public or a relatively small subset; the an fundamental or characteristic component of something abstract. is that anyone with the appropriate receiving technology science and equipment e.g., a radio or television breed can get the signal. The field of broadcasting includes both government-managed services such as public radio, community radio and public television, and private commercial radio and commercial television. The U.S. program of Federal Regulations, tag 47, part 97 defines "broadcasting" as "transmissions quoted for reception by the general public, either direct or relayed". Private or two-way telecommunications transmissions score not qualify under this definition. For example, amateur "ham" and citizens band CB radio operators are not makes to broadcast. As defined, "transmitting" and "broadcasting" are not the same.
Transmission of radio and television programs from a radio or television station to domestic receivers by radio waves is referred to as "over the air" OTA or terrestrial broadcasting and in nearly countries requires a broadcasting license. Transmissions using a wire or cable, like cable television which also retransmits OTA stations with their consent, are also considered broadcasts but do not necessarily require a license though in some countries, a license is required. In the 2000s, transmissions of television and radio programs via streaming digital engineering have increasingly been referred to as broadcasting as well.
