It is important to note that this television was the mechanical version using the Nipkow disk. Baird of Bell Labs used three colored filters to transmit colored images. The first actual demonstration of this technology was done in London, but when the New York Times reported this demonstration they left out the words “in America”. Perhaps an indication of purposeful revising of technological history.
