( t ) he use of two channels, one transmitting the predominating color ( signal T ), and the other the mean brilliance ( signal t ) output from a single television transmitter to be received not only by color television receivers provided with the necessary more expensive equipment, but also by the ordinary type of television receiver which is more numerous and less expensive and which reproduces the pictures in black and white only.

Previous schemes for color television systems, which were incompatible with existing monochrome receivers, transmitted RGB signals in various ways.

Originally, computer monitors were used for data processing while television receivers were used for entertainment.
