The electronic device that delivers the broadcast images and sounds to the receiver is also referred to by the name of the system.

History of Television
Television was invented in 1923 by John Logie Baird in the English town of Hastings. The first television image was also broadcasted by Baird in 1926. Originally dotted and jittery, the quality of images was improved later by Baird. Although Baird’s television system used mechanically rotating discs, rival systems operating electronically, such as the Marconi-EMI system, were also produced at the same time. In the early 1930s, television began to be sold as electronic goods and appealed to large masses.
Color Televisions
Color television work gained its momentum in the 1940s. The first color television went on sale in the USA in the 1950s, but color television began to be widely used in the USA only in the 1960s.
Social impact
Until the start of digital broadcasts, the television audience was only a receiver. Thanks to digital broadcasts, the process of interacting with the user began. The fact that the audience is constantly receptive, television is an easily accessible “resource”, and the effect of using effective visual and auditory elements is high, caused many intellectuals to look down on television. Today, the primary purpose of television broadcasting is based on advertising and commerce. However, a psychological effect has also occurred in the society and a disorder called television addiction has emerged.
