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.
