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.
