You're not listening. RCA's research developed the soon to be Sony "aperture grill" system originally for B&W. This gave a much improved, (sharper), picture. They were selling as many old style B&W sets as they could make and didn't feel the extra cost was worth the improvement, (there may have been picture brightness issues, which would have required further development, I don't know about that, but the system improved perceived sharpness). They sold the patents to Sony.
