Did they also call it a "flat screen"? :-)

If the CRT is flat and not convex they can call it "flat screen"
because it is.

They call it a "flat screen" to fool people into buying it thinking
it is a flat panel TV like an LCD screen. "Flat Screen" was never
marketing hype before flat panels were on the market.

No, flat screen CRTs appeared years ago, well before LCD screens were
any sort of reasonable alternative to CRTs. Flat screen CRTs *were*
different, and commanded a price premium over, non-flat CRTs. The
standard Trinitron or equivalent slot-mask tube typically had a
cylindrical face, while delta-gun CRTs typically had a somewhat
spherical screen face.

(I'm typing this on a flat-screen CRT, a ViewSonic EF70).
