The television has become such an integral part of homes in the modern world that it is hard to imagine life without television. The boob tube, as television is also referred to, provides entertainment to people of all ages. Not just for entertainment value, but TV is also a valuable resource for advertising and different kinds of programming.
The television as we see it and know it today was not always this way. Let’s take a brief look at the history of television and how it came into being.

Timeline of TV History

Different experiments by various people, in the field of electricity and radio, led to the development of basic technologies and ideas that laid the foundation for the invention of television.
In the late 1800s, Paul Gottlieb Nipkow, a student in Germany, developed the first ever mechanical module of television. He succeeded in sending images through wires with the help of a rotating metal disk. This technology was called the ‘electric telescope’ that had 18 lines of resolution.
Around 1907, two separate inventors, A.A. Campbell-Swinton from England and Russian scientist Boris Rosing, used the cathode ray tube in addition to the mechanical scanner system, to create a new television system.
From the experiments of Nipkow and Rosing, two types of television systems came into existence: mechanical television and electronic television.

Mechanical Television History

In 1923, an American inventor called Charles Jenkins used the disk idea of Nipkow to invent the first ever practical mechanical television system. By 1931, his Radiovisor Model 100 was being sold in a complete kit as a mechanical television.
In 1926, just a little after Jenkins, a British inventor known as John Logie Baird, was the first person to have succeeded in transmitting moving pictures through the mechanical disk system started by Nipkow. He also started the first ever TV studio.
From 1926 till 1931, the mechanical television system saw many innovations. Although the discoveries of these men in the department of mechanical television were very innovative, by 1934, all television systems had converted into the electronic system, which is what is being used even today.

Electronic Television History

The experiments of Swinton in 1907, with the cathode ray tube for electronic television held great potential but were not converted into reality. Finally, in 1927, Philo Taylor Farnsworth was able to invent a working model of electronic television that was based on Swinton’s ideas.
His experiments had started when he was just a little boy of 14 years. By the time he became 21, Philo had created the first electronic television system, which did away with the rotating disks and other mechanical aspects of mechanical television. Thus was born the television system which is the basis of all modern TVs.
All the early television systems were black and white, with color television being invented much later on. Since the early invention of television in the beginning of the 1900s, history has seen many firsts in the area of television.
