He links to the whiteboard post, which is interesting because it shows the toothpaste technique for cleaning them. The best buy ever for me was this large, glass whiteboard which is so much easier to erase and clean than a normal whiteboard: https://www.glasswhiteboard.com/

I have to ask. Why is it "white"-board vs. "chalk"-board? Back in elementary school, I learned to call the former "black"-board.

Not an explantion, but I do remember when they first arrived (there was one the year I began high school -- new physics teacher got to set it up how he wanted) and no new ones when I left. I also saw then appear at MIT, again, mainly new construction/renovation.

Chalk boards came in black or green. That name is lost in history, to me. Whiteboards were kind of a shock by comparison -- bright rather than dark -- so it did seem natural. "Marker board" sounds funny now, though it makes sense ("not chalk") but I suppose had it caught on it would be normal. I've only seen "dry erase" used on packages so I assume it's a branding issue.

While the one at my HS was the first one I'd seen (and, seemingly the first any of my classmates had seen, as it was a minor topic of dicussion) I think we'd at least heard of them. This was 1978.

Yes. I got one of these at home and they're awesome. Zero regrets.

So much better than the whiteboard I have in my office at work.

Regional variation? When I was growing up (in California, in the 1970s and 80s), we called them chalkboards because, you know, you used chalk to write on them. Also, they were often green.

Do you call it 'soda' or 'pop'?
