The Inventors
Although, there were many pioneers like; Leon Theremin, Philo Farnsworth, Charles Francis Jenkins, William Bell Boris Rosing and Vladimir Zworkin who designed and developed TV. John Logie Barid was the first person to create live pictures and is considered to be the brains behind successfully designing and developing the television.

First Black & White transmission
The first black and white transmission was created by the famous German inventor Paul Nipkow invented the Nipkow disk in 1884, one of the first successful technologies for television transmission. Hundreds of stations experimented with television broadcasting using the Nipkow system in the 1920s and 1930s, until it was replaced by all-electronic systems in the 1940s.

CRT TV’s (Cathode- Ray Tube) a.k.a Picture Tube
Don’t you recollect your childhood when you hear of CRT TV’s? But do you know, when was it invented and by whom? The first cathode ray tube scanning device was invented by the German scientist Karl Ferdinand Braun in 1897. Braun introduced a CRT with a fluorescent screen, known as the cathode ray oscilloscope. This screen would emit a visible light when struck by a beam of electrons.

Liquid Crystals were accidentally discovered while studying Carrots
In 1888, an Austrian botanist Friedrich Reinitzer while studying cholesteryl benzoate of carrots observed that when heated cholesteryl benzoate initially at 145 degree Celsius it melted and turned into cloudy fluid. And, when it reached 179 degree Celsius it changed again, but into a clear liquid this time. He further even observed and concluded that this substances not only has two melting points but, it reflected polarized light and could rotate the polarization direction of light. Later, in 1960, James Fergason and two colleagues from Westinghouse Electric Corporation proved that a film of liquid crystals exhibited different temperature patterns on the skin. Their research led to the presence of liquid crystals in optical imaging devices, technology still used today.

Analog High definition television actually started in 1936!
Although the quality wasn’t that superior compared to today’s high definition TV it was certainly a revolutionary. Back in 1936, BCC began to transmit world’s first analog high definition television 405 line television broadcasting from the Victorian Alexandra Palace (London), which is considered as the birth place of broadcasting.
Sony used to make pocket-sized TVs
In 1982, Sony was the first brand to mass-produced pocket television - Sony Watchman FD-210. This compact device weighed around 650 grams, with a measurement of 87 x 198 x 33 millimeters. It was also the first flat CRT television produce with tiny 5cm grayscale display.
The Sharp Corporation develops the world’s first 14-inch color TFT LCD TV. The LCD TV model was called the Crystaltron
In 1988 Sharp Corporation succeeded in producing a prototype 14-inch color TFT LCD. For such a significant development in LCD technology, Sharp Corporation was awarded with the Eduard Rhein Technology Award, (referred to in Europe as the Nobel Prize of the AV world) in 1990.

World’s first 3D LED HDTV
The world’s first 3D LED HDTV released by Samsung (Samsung 3D LED 7000) in February, 2010. This model was available in three sizes; 40-inch, 46-inch and 55-inch respectively. Following the trend-setter LG too launched its first 3D LED HDTV (LX9500) in March, 2010.
