Since the invention of television, many great minds have tried to answer this question. However, there's been much debate over who was the first person to invent television. Given the dubious nature of patents and copyrights in the early days of broadcasting, it's all but impossible to know for sure. For years, Russian inventor Vladimir Zworykin claimed that he was the one responsible for creating a functional model of a television based on iconoscope technology in 1924; however, researcher David E. Chalmers proved that the iconoscopes that Zworykin invented were never actually capable of working. This fact has led many to suggest that a Russian engineer named Iablotsky, who patented a similar system in 1905, was the true inventor of television. However, though he had been granted a patent in Russia, it was dismissed by the U.S. Supreme Court due to non-compliance with U.S. patent law regulations (Zworykin got his patent on the same day)Although there have been many great minds who have worked to invent television, none can claim credit for inventing the first practical television receivers used in practice before 1954. These receivers were the result of contributions made by several inventors over a period of more than forty years. Although television research dates back to the 1880s, the lack of sufficiently sensitive light detectors and electronic amplifiers made the practical development of a workable system impossible until well into the twentieth century. It was not until 1907, when University of Pennsylvania researchers (Lee de Forest and Albert A. Michelson) invented the audion that television became a possibility as well as great promise for communication.

The first technical demonstration of television for an audience was given in London on 25th July 1925 by John Logie Baird working with Mr. Fredrick Herring. The first public demonstration of television was carried out by John Logie Baird in London on 23 October 1929, in which he broadcast a simple animated line drawing. Within two years Baird had refined his system, and on 25 July 1930, the BBC was using televisions to show its programmes. However, the use of television for broadcasting was very limited until the advent of coaxial cable systems in the 1930s. By 1931 all television systems used this type of cable, consisting of thin conducting wires wound into spiral patterns which ran from transmitters to receivers and which greatly increased reception distance and signal strength over previously available methods such as crystal sets, arc lamps and acoustic systems.

It was not until after World War II that television began to make its appearance in the public market. The first commercially produced television sets emerged from the radio industry. The companies of RCA and CBS began producing TV receivers in 1939. These sets were short-lived, however, as commercial manufacturing was suspended during the war; they resumed selling models again in 1946. By 1948 television was very popular in the United States, although it would take many more years for it to By the 1950s, most countries had begun broadcasting television programming, and people all over were enjoying programs like Ed Sullivan's show and I Love Lucy, which remain popular today despite their age.
