Farnsworth and Zworykin working separately succeeded in making progress for a TV commercial with a very affordable cost. In 1935, they began to send out broadcast by using a fully electronic system. Their main competitors are Baird Television, which has been first to broadcast since 1928, using a mechanical system entirely. At that time very few people who have a television, and they have a generally high quality pickup. On the TV screen size is only about three to eight inches just so mechanical and electronic competition is not so evident, but the competition is there.

And then RCA and Zworykin ready for a regular TV program, and they demonstrate the large-scale on the World Fair in New York.

CBS has spent a lot of cost for the color. They should realize the fact that their job ends futile. RCA was learned from CBS’s experience started to build the system according to the color format. They quickly build a system that can color on the color and B/W system. After the RCA exhibit their system capabilities, in 1953 NTSC make it became a standard television color system to commercial broadcast.

And now people are always talking through a digital mobile phone and send e-mail via the computer network of the world, but television technology essentially remain the same. Of course there are some procedures such as the development of stereo sound and color is better, but there is not a big leap to be able to shake that perception on the television. However, everything began to change slowly. Television has gradually entered the digital system.
