The first experiments with television broadcasting were
conducted in the 1920's and 1930's in Great Britain and the United States. The
British Broadcasting Corporation or BBC started the world’s first television
broadcast in 1936. A number of television stations were launched after the
First World War in the United States. They were ABC, NBC and CBS. By the early
1950's television programs could be received throughout the United States. By
1960 television became widespread all over the world.
The first television sets were black and white. Black and
white televisions functioned on a monochrome color platform, where the images
were displayed in grey scale. This technology was upgraded by broadcasting
three monochrome images, one of each in three colors of red, green and blue
i.e., R G B. When displayed together they produced a full color image on the
screen. These types of televisions were later called color television. It was
introduced in the early 1950's. During the 50's and 60's the demand for TV sets
increased all over the world. The big commercial stations held the monopoly of
television broadcasting during that time. This monopoly was broken in the 80's
with the rise of cable TV and satellite television. By the mid-1980's there were
a variety of satellite and cable services throughout the world. In the 1980’s
CNN or the Cable News Network started a new age in the history of television
broadcasting. It was the first all-news TV channel in the world. CNN reached
the height of its popularity during the Gulf War as the only TV station that
was in Iraq covering the Gulf War.
Television stations started giving more emphasis on
entertainment programs during the end of 1990's. The reality shows like ‘Who
Wants To Be a Millionaire’, ‘Survivor’, ‘Big Brother’, etc., became an
immediate success during this time. Versions of these shows are being shown in
many countries all over the world.
Reality shows based on dancing and singing also gained
popularity over the public during this period.
In the beginning of 21st century new innovations flooded in
television manufacturing. One of them is the digital television. In Digital
television or D T V the transmission of audio and video is by digitally
processed and multiplexed signal, which is entirely different from signals
used by analog television sets. The advent of digital television allowed
innovations like smart television. Smart television sets are the product of
hybrid or convergent technology. It is a combination of television broadcasting
and internet. Smart television requires integrated set-top boxes for internet
and other facilities. The advent of technology also improved many inventions
like 3 D television and made it easily accessible for the public.
