Television was not invented by a single inventor, instead many people working together and alone, contributed to the evolution of TV.
1831: Joseph Henry's and Michael Faraday's work with electromagnetism makes possible the era of electronic communication to begin.
1862: Abbe Giovanna Caselli invents his "pantelegraph" and becomes the first person to transmit a still image over wires.
1873: Scientists May and Smith experiment with selenium and light, this opens the door for inventors to transform images into electronic signals.
1876: Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a "selenium camera" that would allow people to "see by electricity." Eugen Goldstein coins the term "cathode rays" to describe the light emitted when an electric current was forced through a vacuum tube.
Late 1870's: Scientists and engineers like Paiva, Figuier, and Senlecq were suggesting alternative designs for "telectroscopes."
1880: Inventors like Bell and Edison theorize about telephone devices that transmit image as well as sound. Bell's photophone used light to transmit sound and he wanted to advance his device for image sending. George Carey builds a rudimentary system with light-sensitive cells.
1881: Sheldon Bidwell experiments with telephotography, another photophone.
1884: Paul Nipkow sends images over wires using a rotating metal disk technology calling it the "electric telescope" with 18 lines of resolution.
1900: At the World's Fair in Paris, the 1st International Congress of Electricity was held, where Russian, Constantin Perskyi made the first known use of the word "television."
Soon after, the momentum shifted from ideas and discussions to physical development of TV systems. Two paths were followed:
Mechanical television - based on Nipkow's rotating disks, and
Electronic television - based on the cathode ray tube work done independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing.
1906: Lee de Forest invents the "Audion" vacuum tube that proved essential to electronics. The Audion was the first tube with the ablity to amplify signals. Boris Rosing combines Nipkow's disk and a cathode ray tube and builds the first working mechanical TV system.
1907: Campbell Swinton and Boris Rosing suggest using cathode ray tubes to transmit images - independent of each other, they both develop electronic scanning methods of reproducing images.
American Charles Jenkins and Scotsman John Baird followed the mechanical model while Philo Farnsworth, working independently in San Francisco, and Russian émigré Vladimir Zworkin, working for Westinghouse and later RCA, advanced the electronic model.

Discovered that certain chemicals glowed when exposed to cathode rays. These chemicals were special because they weren’t deflected by the magnetic field produced in the cathode ray tube (which was built by Sir William Crookes in 1870).

The ‘Golden Age of Television’ is what many refer to as the period between the 1950s and 60s when the television began to establish itself as a prevalent medium in the United States. In 1947, the American Broadcasting Company (ABC), Columbia Broadcasting System (CBS), the National Broadcasting Company (NBC), and the Du Mont Network were the four main television networks that ran stations with regular programming taking place. (Television, 2003) While regular television programming was a new innovation, the television itself had been commercially available for over twenty years prior to the 50s. It was conceived by many worldly innovators and went through several testing stages before it was finally completed in the late twenties. The three main innovators were Niplow - who first developed a rotating disk with small holes arranged in a spiral pattern in 1884, Zworykin - who developed the Iconoscope which could scan pictures and break them into electronic signals (a primitive form of the Cathode Ray Tube) in 1923, and lastly Fansworth - who demonstrated for the first time that it was possible to transmit an electrical image in 1927. (Rollo, 2011) However, one of the many reasons why this medium was successful in the 50s was due to the fact that it became more accessible to the public. Television sets were more affordable to middle class citizens which created further interest in the new technology. Through an historical account of the medium, the spread of television across America throughout this particular decade will be examined.
Before analyzing the history of Rock n’ Roll television, the history of how watching television came to become a popular must come into question. To summarize briefly, the invention of television was in development since the 1870s, however the first demonstration of live transmitted images in motion was in 1925 lead by Scottish inventor John Logie Baird (Radio Shows Far Away Objects in Motion). The image was of Baird’s business partner Oliver Hutchinson (Television), showing a mere five frames per second, it was an impressive sight for the time. With perfection of the invention, electronic televisions had been developed by Vladimir Kosma Zworykin with the help of the RCA radio...
From these painting we jump to 1838 with stereoscope and then the view master in 1839. The stereoscope is a device that showed two side by side images or photos that gave the person using the steroscope a sense of immersion. The stereoscope was created by Charles Wheatstone, but then one year later William Gruber approved upon the idea of
The first models of the Camera Obscura were large chambers that could be entered by the artist. At first, this invention was recognized as an aid to artists who could trace the images to create a more realistic impression of the scene. The difficulty with the chamber was that it was not readily portable, and was therefore useless to an artist. This issue was solved when advancements were made in the seventeenth century when inventors developed a portable version of the optical device. Also, those using the instrument found that the image produced was inaccurate in that it defied the rules of perspective because it was formed by a single lens. Inventors discovered a way to correct this problem, as explained in the History of Photography:
The movie camera was developed during the height of his career; sometime referred to as the Kinetoscope, an early motion picture device from the Greek word Kinesis, (CITE). In 1888, Thomas Edison began working on the Kinetoscope. Using the income from his technological inventions, Thomas Edison built the largest and most advanced laboratory at the time in West Orange, New Jersey. Edison and his staff of scientists and skilled craftsmen began working on the Kinetoscope. During the production of the Kinetoscope, Edison attended a lecture in Orange, New Jersey with photographer Edward Muybridge to discuss stop action photographs of animals in motion. Edison later invited Mr. Muybridge to his laboratory where Thomas Edison learned how to create the illusion of still life photos into

and decided to look into it. At this time television had already been invented by some inventors such as Paul Nipkow
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
First of all the developer of this innovation was Nikola Tesla ; a Serbian- American Engineer and Physicist. His first project was the AC motor generator and the development of transmissional technology. His success with this lasted until he had an argument with his boss because of his mad scientist
