The first
experimental radio broadcasts were made in Britain in1921.
They led to the
formation a few months later of the British Broadcasting Company (later
Corporation). This was at the instigation of the General Post Office (GPO), who
wanted to see the formation of a single consortium of wireless equipment
manufacturers and broadcasters, specifically to avoid the major confusion that
had arisen in North America, where there were 500 rival stations.
The new company worked
under Johan Reith, an engineer from Aberdeem who was the company´s general
manager for its first 16 years. Under Reith´s leadership, the BBC became a major national institution. The broadcasts were entirely live, and Reith insisted on a high level of formality, in spoken
English, behaviour and dress, traditions which have unfortunately been
thrown to the four winds in recent years.
The London
broadcasting station, Known as 2LO, went on the air on 14 November 1922 as the
British Broadcasting Company. A news bulletin was read by Arthur Burrows of the
Marconi Company. The initial broadcast were fairly short, but soon lengthened
to four hours a day of news, talks and concerts.
The BBC was supported
financially by license fees paid for by the users. They had to pay ten
shillings a year (50 pence) for the privilege of operating a receiver. The same
system was used when television was introduced, also by the BBC.
At the same time in
North America, the first commercial radio was being broadcast. The New York station,
WEAF, broadcast the first radio commercials. This different approach to
broadcasting was to become the set pattern in North America - private control
of the airwaves and programmes dominated by sponsors.
In 1923, the BBC began publishing its magazine, the
Radio Times, so that listeners would
know in advance what programmes were to be broadcast; this too became a long-continuing practice.
By 1926, radio
ownership in The United States reached three million; most of these radios
required listeners to wear earphones. In 1926, NBC ( the National Broadcasting
Company ) was founded by David Sarnoff; this ambitious project had nine
stations.
The first experiments
with television followed hard on the heels of radio.
It was in 1926 that John Logie Baird gave his first public demonstration
of television, but the system he used was bases on the rotating disc invented
by van Nipkov in 1886 and had serious limitations.
Television had its
first American demonstrations in 1927 in the auditorium of New York´s Bell
Telephone Laboratories. Walter Gifford showed a large audience Commerce
Secretary Herbert Hoover in his office in Washington while Hoover´s voice was
transmitted over telephone wires. The development of television was seriously
inhibited by the fact that it needed a frequency band of four million cycles
compared with only 400 for a radio; this was because of the need to transmit
250.000 elements required to build a clear picture on the screen.
The first regularly scheduled TV programmes started on
11 May 1928. General Electric´s station
in New York broadcast the first
programmes.
Another contributing
development was the invention of the first tape recorder. The blattnerphone
designed by the German film producer Louis Blattner used magnetized steel tape.
Blattner himself used his invention to supply synchronized sound tracks to the
films he was making at Elstree studios. The BBC saw straight away that the tape
recorder was going to be invaluable to them, not least for making recorded
programmes, and acquired the first commercially produced blattnerphone in 1931.
Both radio and
television continued to develop. In the United States 75.000 radio sets were
sold in 1921; by the end of the decade sales had increased to over 13 million.
It had become a major communicator. It had also become big business. American
advertisers were spending 60 million dollars on radio commercials.
