Explanation:

Television is a system for the transmission and reception of remote images and sound that simulate movement, which uses a diffusion mechanism. The transmission can be carried out by means of radio waves, by cable television networks, satellite television or IPTV, which exist in open and payment modalities. The television is the signal receptor.

It is at the end of the 20th century when television becomes a true technological flag of the countries and each one of them develops their national and private TV systems. In 1953, Eurovision was created, associating many European countries by connecting their TV systems through microwave links. A few years later, in 1960, Mundovisión was created, which began to make links with geostationary satellites covering the whole world.
