Television Evolution

Television played an important role in the modern life by replacing the radio as the important mass medium in the 1950s. Many people worldwide feel difficult to imagine being without a TV. TV is reflecting and also shaping cultural values and providing the best entertainment for individuals of every age group. It is the suitable time to take note of the evolution of the TV and make a better-informed decision about the TV design and development efforts in different periods. Of course now we have the internet that allows everything from purchasing a product from across the world, watching live streams of almost anything, and finding a hook up on a meet and fuck site. While today’s generation take internet for granted, in the past, TV was king. Though Internet technology and the latest satellite broadcasting technology aid in the communication and entertainment for all users, TV continues to evolve and keeps in a position in a list of the best inventions in the 20th century.

TV technology related inventions from specialists

George Carey, Boston civil servant envisioned the overall TV systems in 1876 by putting forward drawings for the popular selenium camera which would let individuals to see by electricity in 1877. More than a few technological developments during the late 1800s set the stage for TV. Karl Ferdinand Braun, German physicist invented the Cathode Ray Tube (CRT) in 1897. This system is the forerunner of the TV picture tube. This system combined the principles of electricity and camera. The florescent screen in this system emitted a visible light in the form of images when it struck by electron beams. Paul Nipkow, German inventor invented the scanning disk in 1880s. The light passed through holes when the disk rotated and separate pictures into pinpoints of light which could be transmitted as a series of electronic lines.

The golden age of the TV

Boris Rosing, Russian scientist used both the mechanical scanner system and the CRT in 1907 in an experimental TV system. He used the focused electrons for the purpose of displaying images with the CRT in the receiver. He used the mechanical disk system in this experimental TV as a camera and invented the primitive TV system. John Logie Baird, British inventor developed the mechanical TV out of the disk system of Nipkow. He gave the first public demonstration of the TV system in 1926 at the department store Selfridge in London. He extended his system in 1928 by transmitting a signal between New York and London. This mechanical system was adopted by the BBC by 1932. Baird developed and sold first 10000 sets of commercially viable TVs.

The national television system committee enhanced its efforts to develop all-electronic color systems compatible with the black and white TV sets and received approval for it in 1953. The golden age of TV is 1950s. Donald Bitzer, Robert Willson and Gene Slottow invented the first prototype for the plasma display monitor. James Fergason played a vital role behind the advancement in the LCD TV in 1960s and today’s LCD TV technology. Nowadays, OLED technology as well as thin film transistor circuits make TVs bright, light, thin and better striking color gamut and contrasts. Sony launched the first ever OLED TV XEL-1 in 2007. However, this TV is still evolving.
