Television
(mainly abbreviated as “TV”) is a telecommunication medium, a
bidirectional path for moving images that can be monochrome or
coloured with optional accompanying sound.
The
first TV was invented in 1884 by the German student Paul Nipkow and
in 1925, John Baird, a Scottish inventor, succeeded in transmitting
moving silhouette images through Nipkow’s machine. It had 30 lines
resolution. In 1926 it appeared one with 40 lines resolution, in 1927
one with 100 lines resolution and so on. In 1940, it had started to
be developed the coloured TV transmission.
The
television has been improving since then and nowadays it’s
completely different, as trying to compare Nipkow’s TV with the
actual Smart TV, so we have to notice the incredibly fast evolution.
In only one century we came to this.
And
about the TV broadcasting, the oldest TV station is “WGY
Television”, which had been in experimental use since the beginning
of 1928. Later in the same year, it also appeared “WNBC”. As both
stations were experimental, none of them had a regular program
as receivers were operated by
engineers within the company “General Electric” from New York,
the parent of the stations. In August 1936, the “Olympic
Games” in Berlin were carried by cable to television stations
in Berlin and Leipzig, where the public could view the games live.
Comparing,
we have been raised with hundreds of TV posts but imagine that for
more than 20 years most countries had had only one station.
Relating
to what’s used to be played on the TV nowadays, here are some
examples: movies, TV series, talk-shows, reality-shows, news,
researches and so forth.
