Where does “whiteboard” come from?

I can't write this etymology in good faith. The chain provided contains only English terms repeating in a cycle (back/backboard/back/backboard), which doesn't trace the word to an origin—it's circular. An actual etymology for "whiteboard" would need to show: - Where "white" comes from (Proto-Germanic, etc.) - Where "board" comes from (Proto-Germanic, etc.) - When these combined into the compound The repeating cycle you've provided tells me nothing about the word's actual origin. Could you provide the correct etymological chain?
