American TV programs, like American popular culture in general in the 20th and early 21st centuries, have spread far beyond the boundaries of the United States and have had a pervasive influence on global popular culture.
Introduction Broadcasting, Radio and Televisionprimary means by which information and entertainment are delivered to the public in virtually every nation around the world. The term broadcasting refers to the airborne transmission of electromagnetic audio signals radio or audiovisual signals television that are readily accessible to a wide population via standard receivers.
Broadcasting is a crucial instrument of modern social and political organization.
At its peak of influence in the midth century, national leaders often used radio and television broadcasting to address entire countries. Because of its capacity to reach large numbers of people, broadcasting has been regulated since it was recognized as a significant means of communication.
For more information, see the section "The Regulation of Broadcasting. Previously a synonym for radio and television, broadcasting has become one of several delivery systems that feed content to newer media.
The Emergence of Broadcast Communication Throughout history, long-distance Radio and redefined television viewing had depended entirely upon conventional means of transportation. A message could be moved aboard a ship, on horseback, by pigeon, or in the memory of a human courier, but in all cases it had to be conveyed as a mass through space like any other material commodity.
Radio Broadcasting The story of radio begins in the development of an earlier medium, the telegraph, the first instantaneous system of information movement. Patented simultaneously in in the United States by inventor Samuel F.
Morse and in Great Britain by scientists Sir Charles Wheatstone and Sir William Fothergill Cooke, the electromagnetic telegraph realized the age-old human desire for a means of communication free from the obstacles of long-distance transportation.
The first public telegraph line, completed inran about 64 km about 40 mi from Washington, D. Morse's first message, "What hath God wrought? The usefulness of telegraphy was such that over the next half century wires were strung across much of the world, including a transatlantic undersea cable about connecting Europe and North America.
The instantaneous arrival of a message from a place that required hours, days, or weeks to reach by ordinary transport was such a radical departure from familiar experience that some telegraph offices were able to collect admission fees from spectators wanting to witness the feat for themselves.
Despite its accomplishments, telegraphic communication was limited. It depended on the building and maintenance of a complex system of receiving stations wired to each other along a fixed route. The telephone, patented by American inventor Alexander Graham Bell inrequired an even more complex system.
The printed word remained the only medium by which large numbers of people could be addressed simultaneously. Radio Experiments Scientists in many countries worked to devise a system that could overcome the limitations of the telegraph wire.
In Italian inventor Guglielmo Marconi transmitted a message in Morse code that was picked up about 3 km about 2 mi away by a receiving device that had no wired connection to Marconi's transmitting device. Marconi had demonstrated that an electronic signal could be cast broadly through space so that receivers at random points could capture it.
The closed circuit of instant communication, bound by the necessity of wires, had at last been opened by a so-called wireless telegraph.
The invention was also called a radiotelegraph later shortened to radiobecause its signal moved outward in all directions, or radially, from the point of transmission.
The age of broadcasting had begun. Unable to obtain funding in Italy, Marconi found willing supporters for his research in Britain, a country that depended on the quick and effective deployment of its worldwide naval and commercial shipping fleets to support its empire.
Marconi moved to London in and founded the British Marconi Company to develop and market his invention for military and industrial uses. Within five years a wireless signal had been transmitted across the Atlantic Ocean from England to Newfoundland, Canada.
Marconi was awarded the Nobel Prize for physics in Broadcasting advanced on other fronts as well. In the United Fruit Company hired American inventor Lee De Forest to help build a series of radio broadcasting stations in the Caribbean basin for the purpose of facilitating greater efficiency in shipping perishable goods from Central America to ports in the United States.
These linked stations, which shared current information on weather and market conditions, constituted the first broadcasting network. The work of Canadian inventor Reginald Fessenden, later elaborated upon by De Forest, allowed for the broadcast transmission of a wider range of sounds, including the human voice.
Within a decade, wireless telegraphy had developed into a basic tool of the world maritime industry, with many countries requiring by law that flag vessels vessels, registered under national flags, that engage in international trade have both a radio transmitter and a certified operator aboard at all times.
Despite all this commercial activity, little attention had been given to general consumer applications for the new technology. Instead, nonmaritime broadcasting was dominated by experimenters and hobbyists.NEWBURY PARK, Calif., May 28, /PRNewswire/ -- For FiOS TV customers in Southern California, their TV-viewing experience will never be the same as Verizon introduces FiOS Quantum TV (www.

Television viewing is a regular part of American daily life. Many Americans, especially children ages 8 to 18 watch television more than hours a week (Espejo). Approximately 38 hours of these is spent watching commercial media (Rowe and Ruskin ).
