Amid a fierce technical rivalry between CBS and RCA over incompatible color television systems, CBS advanced its early field-sequential color technology through further test broadcasts in this period, though the format would ultimately lose out to the RCA-developed NTSC compatible-color standard formally adopted the following month by the FCC in December 1953.
Television in the early 1950s was consumed by a ferocious standards war. CBS had developed a field-sequential color system that produced vivid images but required a spinning color wheel inside bulky, incompatible receivers, meaning existing black-and-white television sets could not receive its broadcasts at all.
RCA, led by the formidable David Sarnoff, pushed a rival compatible-color system, engineered so that black-and-white sets could still receive a viewable picture from color broadcasts while color sets displayed full hue. Throughout 1953, both companies staged demonstration broadcasts to sway regulators, engineers, and the viewing public in what amounted to a proxy war for the future of American television infrastructure.
CBS's approach, while technically impressive in color fidelity, was a commercial dead end because of its incompatibility, and by December 1953 the FCC reversed its earlier approval of the CBS standard in favor of RCA's NTSC-compatible system, which would become the American television standard for the next four decades until digital transition.
