Television (TV) is a well-known telecommunication media that functions as a recipient of broadcasts of moving images and sounds, both monochrome (black and white) and colored. The word television is a combination of the words tele (far) from Greek and visio (vision) from Latin, so television can be interpreted as a remote communication tool that uses visual media.

The use of the word Television can also refer to television boxes, television shows, or television transmissions. The invention of television was paralleled by the discovery of the wheel, because this discovery was able to change world civilization.

Television boxes were first sold commercially since the 1920s, and since then television has become an ordinary item in homes, business offices, and institutions, especially as a source of needs for entertainment and news and as an advertising medium. Since the 1970s, the emergence of video tapes, laser discs, DVDs and now Blu-ray discs, has also made television boxes a tool for viewing broadcast material and recordings. In recent years, television broadcasts have been accessible via the Internet, for example via iPlayer and Hulu.

In the early days of its development, television used a combination of optical, mechanical, and electronic technology to record, display and broadcast visual images. However, in the late 1920s, television systems that only used optical and electronic technology were developed, where all modern television systems applied this technology. Although mechanical systems were finally no longer used, the knowledge gained from the development of electromechanical systems was very important in the development of full electronic television systems.

The first image that was successfully sent electrically was through a simple mechanical fax machine, (such as the pantelegraph) developed in the late 19th century. The concept of sending mobile images using electric power was first described in 1878 as a telephoneoscope (the combined concept of telephone and moving images), not long after the invention of the telephone. At that time, science fiction writers had imagined that someday light would also be able to be transmitted through a cable medium, like sound.

The idea of using an image scanning system to send images was first practiced in 1881 using pantelegraf, which used the pendulum scanning mechanism. Since then, various image scanning techniques have been used in almost every image sending technology, including television. This is a concept called perasteran, which is the process of converting visual images into electric wave currents.
