Who invented the TV and the computer?

Answer 1

Like all complex devices, the television had many contributing inventors.

During the 1870s there were several people who worked on photo-electric devices that converted light into an electrical signal.

1876 was the year that Nipkow patented a rotating disc that could be used to capture and display an image using electricity. Although he had the patent, he never developed a useful working system with the disc and the patent expired some twenty years later.

John Logie Baird, a Scot living in England is recognized as the first to demonstrate an operational television in March of 1925. It was a public demonstration held in Selfridges, a London department store. His "Televisor" system showed moving images being delivered via an electrical signal. The system used the Nipkow disc to produce the images so Baird's work was based on research carried out many years before. Despite the use of the disc, Baird was the first to successfully produce an operational television.

The BBC began public television broadcasts in January 1929 using Baird's system from their London television studio. These continued for seven years until they moved to a new fully electronic system in 1936.

Meanwhile, Philo Farnsworth was working on similar ideas in America and in 1927, he also demonstrated an electro-mechanical television system. Just two years later in 1929, he demonstrated a fully electronic system with no moving parts. This was an important development as there were significant limitations with the electro-mechanical systems. Farnsworth's electronic system provided a means to increase resolution far beyond that of the Nipkow method.

Vladimir Zworykin, a Russian American filed a patent application in 1923 for the "iconscope", the first electronic camera tube. The patent was eventually granted in 1933. Zworykin worked with RCA during the 1930s and it was RCA who began the first commercial broadcasts of television in the US in 1939. His Iconscope tube was used for the first few years of broadcasting until it was replaced by more sensitive and higher resolution tubes during the 1940s.

For Computer:

Who invented the computer and what year?" The answer to the first part of the question is Charles Babbage. Interestingly, the implementation of the design of what should have been the first computer was actually completed in 1989. But, if the question is "Who invented the computer first and electronically?" then it is John Presper Eckert & John W. Mauchly. They built the ENIAC (Electronic Numerical Integrator and Computer). Then why is Charles Babbage given the credit of inventing the computer? Charles Babbage was the first person to introduce the idea of "programmable machines". Charles Babbage hardly imagined that his distaste for human errors would one day result in inventions such as desktop computers and laptop computers.

To reach today's era of Artificial Intelligence, natural language processing and high power processing, computer inventions had to go through various generations. This all started with Charles Babbage's difference engine in 1822. The difference engines and analytical engines (if completed) would be heavily mechanical. Their weight would be in tons (although analytical and difference engine are not considered to be of any generation, let us consider them to be of zeroth generation for the sake of reference). The main feature of first generation (1940 - 1956) computers was vacuum tubes. The architecture of second generation (1956 - 1963) computers was based on transistors. Third generation computers (1964 - 1971) saw the introduction of integrated circuits. And fourth generation (1971 - present) computers are based on microprocessors. And now we are in the fifth generation (present - henceforth) of computers, where artificial intelligence takes precedence. Following is the story of the man who invented the computer, and when he did that, little did the world know that Charles Babbage had managed to alter the course of history .
