The television has been commercially available since the late 1920s, and is considered a staple in modern households for entertainment and in the business world for advertising purposes.
The first concept of a television arrived in 1878, as television images were sketched in the form of the telephonoscope, which followed the invention of the telephone.
This idea came to life in 1881 in the pantelegraph, which used pendulum-based scanning.
The first electromechanical television system was patented in 1884 by a 23 year-old university student in Germany named Paul Gottlieb Nipkow. It incorporated the use of a scanning disk for rasterization.
This disk was later used by Scottish inventor John Logie Baird, who had succeeded in his demonstration of the transmission of moving silhouette images in 1925 in London. He was able to transmit monochromatic images a year later.
This disk was able to produce an image composed of 30 lines resolution, which was just enough to discern a human face from photographic lenses.
In the same year, Kenjiro Takayanagi was able to up Baird by being able to produce 40 lines resolution, which was the first working example of an electronic television receiver.
The oldest television station is traced back to WRGB, which was founded on January 13, 1928. The show station was broadcast from the General Electric factory, located in Schenectady, NY. The second radio station was started by General Electric’s new facility in New York City in 1928. This station was called W2XBS, which is known today as WNBC.
There was no regular programming on these stations since they were purely experimental. However, an image of a Felix the Cat doll that was rotating on a turntable was broadcast on television for two hours a day for several years, as a way to test the new technology.
The Olympic Games in August 1936 were able to be carried to television stations in Berlin, and in November 1936, BBC aired a public service announcement from the Victorian Alexandra Palace in north London.
At this time in the history of television, all broadcasting had been done in black and white. However, Mexican inventor Guillermo Gonzalez Camarena experimented with television, which led to his patent of the color television in 1940.
