In answer to your questions on your other threads. Westinghouse was first in marketing a color set in Feb. 1954. They beat RCA by about 2 months. There is some evidence that Admiral offered a 15" color set in Dec. 1953, but this has still not been documented. As far as color movies on tv in the 50's. The "Wizard of Oz is the best example. It first aired on CBS in color in 1956.I believe NBC aired "Richard the III. in color in 1955.
