I want to call false on the claim that this is s the biggest crt ever made. I used to work in a computer recycling center in the monitor testing area bak in 2007. One day a giant 60 inch blue aluminum industrial sized sony trinitron was brought in by the fork trucks for me to test. There was 2 of them from a large conference room at xerox or kodak or used by a tv station. They were bigger than an average pallet and took a forklift to move them.

That was most likely a rear projection unit, they looked kind of like CRTs but it's different technology. Sony did make them although they weren't marketed as Trinitrons AFAIK.

Projection displays were CRTs, but they were small (10" or so) and monochrome. Three of them—one each for the red, green, and blue channels, were each oriented and focused to project a clear image at the exact same spot on the screen, overlaying each other to form a single color image.

Projection TVs were even prone to CRT "raster burn", perhaps even more so than single-tube TVs due to the brightness of the image required, which is why Nintendo instruction booklets had stern warnings not to use their consoles with projection TVs.

Yea, but the screen you could see wasn’t a CRT tube. It was just a projection screen but unless you looked closely you’d be unlikely to notice.

Tell me you lived in Rochester, NY without saying so.

Yeah. I remember growing up with a Trinitron flat CRT that I thought was humungous. TIL 43 inches is the upper limit for CRTs.
