Another day, another Trinitron

Of course, only the Trinitron had the tensioned-grill shadow mask (with a cylindrical contour). All the other in-line tubes had a solid shadow mask, with short vertical slots and even shorter cross pieces defining the ends of the slots.

You're right, I do not recall ever seeing any TV sets made around the same time as the late-model Trinitrons that have the vertically flat picture tube. Is a tensioned-grille shadow mask the same thing as an aperture grille?
