History Of The Television

Console Television Receiver by ellenm1

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.

History Of The Automobile

It is estimated that the first automobile design was steam-powered and most likely built in China around 1672 by Ferdinand Verbiest. The vehicle was a 65 cm-long toy for the Chinese Emperor that was for display purposes since it could not carry a driver or passenger.

Nicolas-Joseph Cugnot received credit for building the first mechanical vehicle in the form of a steam-powered tricycle in 1769. However, his steam engine ran into a couple of problems with maintaining water supply and steam pressure.
Richard Trevithick built a road locomotive in 1801, which is what some believe is the first moving demonstration of a steam-powered vehicle.

While Nicéphore Niépce and his brother Claude were most likely the creators of the first internal combustion engine, Karl Benz is credited as the modern automobile inventor.

Benz was granted a patent in 1879 for an engine he had designed the year before. He built his first Motorwagen in 1885 in Germany, and began the promotion of his vehicle in 1886.

When the first four-wheeler vehicle of his was introduced, about 25 Benz vehicles were sold between 1888 and 1893.

The first road trip by car was taken by Benz’s wife Bertha Benz in August 1888, which proved the road-reliability of the vehicle’s invention.

Mass production of vehicles came to be by the idea of Ransom Olds in 1902. He had an Oldsmobile factory in Michigan that relied on assembly lines of mass production and interchangeable parts. Henry Ford expanded this concept in 1914, and his cars were being finished in each step in 15 minutes.

Today the automobile is one of the most popular inventions, and many consider it to be a necessity.

History of the Radio

The radio was the first device to allow for mass communication, and it actually owes its development to two other inventions – the telegraph and the telephone. Radio technology began as “wireless telegraphy”. 

Henirich Hertz was the first to prove that you could indeed transmit and receive electric waves wirelessly. Even so, Guglielmo Marconi was the one who demosntrated the feasibility of radio communication. The Italian inventor sent and received his first radio signal in 1895. He is the inventor widely recognized for being the first to build a radio transmitter and bring radio into people’s homes, even though another inventor, Nikola Tesla, is officially credited with being the first person to patent radio technology.

The radio grew tremendously over the years. Lee Deforest is considered “the Father of American radio” – his work lead to the invention of amplitude-modulated or AM radio, which allowed for a multitude of radio stations. Deforest is also known as the first person to ever use the word “radio”.

Speech was first transmitted across the continent from New York City to San Francisco and across the Atlantic Ocean from Naval radio station NAA at Arlington, Virginia, to the Eiffel Tower in Paris. This happened in 1915. Five years later, on November 2, 1920, Westinghouse’s KDKA-Pittsburgh broadcasted the Harding-Cox election returns; they soon began a daily schedule of radio programs. Edwin Howard Armstrong invented frequency-modulated or FM radio in 1933. He managed to improve the audio signal of radio by controlling the noise static. 

Over the years, radio technology has grown significantly. Think about it: everything from baby monitors to cell phones are applications of radio. Furthermore, taxi drivers and package delivery services are also reaping the benefits of mobile radio. Last but not least, Internet radio is extremely popular, and allows individuals to easily listen to various international stations without any hassles.
