Color television refers to the reception of color television.
Most researchers understood the importance of the transmission of color images, a first patent in Russia in 1889 for an electronic scanning color system shows that this desire is old. John Logie Baird showed the first color transmission, using rotating disc scanners with color filters in transmission and reception. In 1938, the shadow mask system for television was patented by Werner Flechsig in Germany. The color television was shown at the International radio exhibition Berlin in 1939.
On August 16, 1944, Baird made the first demonstration of a fully electronic color display. His 600-line system used triple interlacing, with six scans per frame.
In September 1951, in the United States, the Columbia Broadcasting System channel presented its color television system, the N.T.S.C. (National Television System Committee). The first color television is marketed, the RCA CT-100 (in), in April 1954.
In France, the system chosen for color television is SECAM (Color sequential memory), developed by Henri de France.
Nearly 40 color processes were reviewed and after several years of experimentation, the first color program was inaugurated in France on October 1, 1967.
