    There certainly are such things as CRT rear-projection sets, but they're not very common these days. The standard type of CRT TV is not rear-projection, though, it's what's called "direct view" CRT.

    The difference is that in a normal CRT set you have a single cathode-ray-tube which has three different colours of phosphor on it, and the image you see is a direct view of the phosphors glowing.

    With CRT rear-projection you have three separate tubes internally, one red, one green, one blue. Each tube projects its own picture, and the three pictures are combined on a screen - what you see is therefore three different CRT images all projected onto the same screen.
