The history of television is probably one of the biggest stories of the century. The history of American television began long before the marketing of the first receivers in the late 1940s.It took a long time to develop the technology for television. The concept of the television was implemented by the masters of radio and the structures for it were developed between 1919 and 1927.

Thanks to a succession of discoveries, it has not one but several fathers. Television is the electric transmission and reception of visual images. It is probably the first invention created by taking into account the ideas of hundreds of separate individuals motivated by the desire to produce a system "that sees beyond the horizon"

Thus, each country has its own television history.
Before the Second World War, television was already present in some industrial countries, including the United States.

In this paper, we look at the beginnings of television in the United States and analyze the succession of discoveries that created this new invention. We also look at the actors who played important roles in popularizing this medium and how this invention was introduced to American life.

The discovery that began the process of the invention of the television was G. Caselli's pantelegraph. The Pantelegraph (invented in 1863) transported texts and drawings by telegraph lines. Then came the inventions of photoelectricity which was discovered by C. May in 1873 and Phototelegraphy by A. Korn in 1907.
The production of radio waves from electromagnetic waves was developed by Hertz in 1887.

The decomposition and recomposition of an image by analyzing a number of points and lines (at the same time but separately)were studied by American G. Carey and French scientist C. Senlecq.

These were the discoveries that began the process that led to the invention of the television.

A session of the International Congress of Electricity was held in 1900 (in conjunction with an exhibition) in Paris. On August 25, 1900 Constantine Perskyi read a paper that was titled ?Television'. In this paper he described a device that was based on the magnetic properties of selenium. This was the birth of the term Television

Alan Archibald Campbell Swinton wrote that remote viewing was possible with the use of CRTs(Cathode Ray Tubes). This was the first mention (in literature) of a fully electric television system.

The cathode ray tube (CRT) was invented by Karl Ferdinand Braun. This was at the heart of the original Television sets. It is a device that consists of a heated filament, cathodes and anodes in the form of lenses. A potential difference (voltage) creates an electric field that accelerates the electrons. These electrons knock against one edge of a flat screen which is layered with a fluorescent layer that responds to impact of the electrons by creating a bright spot.
