When did color tv come out what year?
During its campaign for FCC approval, CBS gave the first demonstrations of color television to the general public, showing an hour of color programs daily Mondays through Saturdays, beginning January 12, 1950, and running for the remainder of the month, over WOIC in Washington, D.C., where the programs could be viewed on eight 16-inch color receivers in a public building. Due to high public demand, the broadcasts were resumed February 13–21, with several evening programs added. CBS initiated a limited schedule of color broadcasts from its New York station WCBS-TV Mondays to Saturdays beginning November 14, 1950, making ten color receivers available for the viewing public. All were broadcast using the single color camera that CBS owned. The New York broadcasts were extended by coaxial cable to Philadelphia's WCAU-TV beginning December 13, and to Chicago on January 10, making them the first network color broadcasts.

While the CBS color broadcasting schedule gradually expanded to twelve hours per week (but never into prime time), and the color network expanded to eleven affiliates as far west as Chicago, its commercial success was doomed by the lack of color receivers necessary to watch the programs, the refusal of television manufacturers to create adapter mechanisms for their existing black-and-white sets, and the unwillingness of advertisers to sponsor broadcasts seen by almost no one. CBS had bought a television manufacturer in April, and in September 1951, production began on the only CBS-Columbia color television model, with the first color sets reaching retail stores on September 28. But it was too little, too late. Only 200 sets had been shipped, and only 100 sold, when CBS discontinued its color television system on October 20, 1951, ostensibly by request of the National Production Authority for the duration of the Korean War, and bought back all the CBS color sets it could to prevent lawsuits by disappointed customers. RCA chairman David Sarnoff later charged that the NPA's order had come "out of a situation artificially created by one company to solve its own perplexing problems" because CBS had been unsuccessful in its color venture.

Transmission of color images using mechanical scanners had been conceived as early as the 1880s. A practical demonstration of mechanically-scanned color television was given by John Logie Baird in 1928, but the limitations of a mechanical system were apparent even then. Development of electronic scanning and display made an all-electronic system possible. Early monochrome transmission standards were developed prior to the Second World War, but civilian electronics developments were frozen during much of the war. In August 1944, Baird gave the world's first demonstration of a practical fully electronic color television display. In the United States, commercially competing color standards were developed, finally resulting in the NTSC standard for color that retained compatibility with the prior monochrome system. Although the NTSC color standard was proclaimed in 1953 and limited programming became available, it was not until the early 1970s that color television in North America outsold black and white or monochrome units. Color broadcasting in Europe was not standardized on the PAL and SECAM formats until the 1960s.

Color television is a television transmission technology that includes information on the color of the picture, so the video image can be displayed in color on the television set. It is considered an improvement on the earliest television technology, monochrome or black-and-white television, in which the image is displayed in shades of gray (grayscale).
