Broadcasting

The word ‘broadcasting’, referring to radio transmissions, was originally an agricultural word for the wide scattering of seeds.

Reginald Fessenden transmitted the first radio broadcast in 1906. It consisted of a poetry reading, a violin solo, and a speech.

In April 1909 Charles David Herrold, an electronics instructor in San Jose, California, constructed an early radio station. He coined the terms "narrowcasting" and "broadcasting" respectively to identify transmissions destined for a single receiver such as that on board a ship, and those transmissions destined for a general audience.

Italian inventor Guglielmo Marconi's Writtle, near Chelmsford  research center was the location of the first officially publicised sound broadcasts in the UK. One of them featured Dame Nellie Melba.

The first radio broadcast license by the U.S. Commerce Departmen was given in 1920 to Westinghouse for station KDKA in Pittsburgh. On November 2, 1920, KDKA broadcast the US presidential election returns from a shack on the roof of the K Building of the Westinghouse Electric Company "East Pittsburgh Works" in Turtle Creek, Pennsylvania. The original broadcast was said to be heard as far away as Canada.

Through the next month semiweekly broadcasts were made, until December 21, 1930 when KDKA embarked on an ambitious daily schedule, initially for about an hour each evening.

When broadcasting began, directors had to communicate with people on the air without making noise, so they developed hand signals. Time is always a key element in live broadcasts. The person at the mike needed to know if the program was on schedule. If things were "just right," the director signaled with a finger to the side of his or her nose.

In 1936, England became the first country in the world to provide regular public broadcasting on television.

In 1943 RCA sold the NBC Blue radio network to Edward Noble for $8-million. Noble renamed the network the American Broadcasting Company, ABC

The first "networked" television broadcasts took place in 1949 when KDKA-TV in Pittsburgh, Pennsylvania went on the air connecting the east coast and mid-west programming.

NBC made the first coast-to-coast NTSC color broadcast in 1954 when it telecast the Tournament of Roses Parade, with public demonstrations given across the United States on prototype color receivers.
