RCA 1960 color and B&W TV marketing films

[nasadowsk]

Why did RCA hang onto kinescope for so long? Wasn’t it something like Philco or someone else had the trademark for “picture tube”? Also, I think Ampex had the trademark fir videotape early on.

Or it could have just been RCA adopting weird names fir things. Ultor?

Kinescope was Zworykin's name for the device, so RCA used it and other makers avoided it.
