- 1950 – CBS’s field-sequential colour system for television is the first to be licensed for broadcast by the US Federal Communications Commission.
Field-Sequential Colour System
A field-sequential colour system (FSC) is a colour television system in which the primary colour information is transmitted in successive images and which relies on the human vision system to fuse the successive images into a colour picture. One field-sequential system was developed by Dr. Peter Goldmark for CBS, which was its sole user in commercial broadcasting. It was first demonstrated to the press on 04 September 1940, and first shown to the general public on 12 January 1950. The Federal Communications Commission adopted it on 11 October 1950, as the standard for colour television in the United States, but it was later withdrawn.
