  1. Teletext: such a hack that, if the signal quality degrades, it will be the first thing to go. You know what really was a marvel in the days of analog TV? NICAM digital stereo sound, that’s what.

  2. 8:10 Ah, but what about the thin horizontal line running across the screen about two-thirds of the way up? I think that was a wire that was needed to reinforce the aperture grille. Almost unnoticeable -- until someone points it out to you.

  3. 9:16 Ah, you did mention it.

  4. Further thought: you put the wire at one third of the way up, whereas I seem to remember with the Apple monitors it was two thirds of the way up. I think Apple felt it would be less noticeable if the tube was flipped upside down.

  5. 5:28 Also used in computer monitors, like Apple’s legendary 13" RGB monitor from 1987 -- commonly considered to be the first colour monitor to be good enough to be used in black-and-white!

  6. 11:06 Ah, you mentioned that too.

  7. Have you ever seen a Zenith FTM (Flat-Tension Mask) set? That was a CRT with a truly flat screen. I don’t think they were very successful, though.

  8. I never used one, but I read reviews which said that, after years of staring at convex CRT screens, the Zenith gave one the illusion of actually being concave. One benefit from being at least vertically flat (both the Sony Trinitrons and the Zenith FTM) was less reflection from overhead lights in an office.

  9. 2:38 I remember looking at the back of a Siemens set around the mid-1970s. I could see about two dozen separate little adjustment knobs, each with its little graphic indicating its effect on the three electron beams. What happened to all those adjustments? By the time I bought a new Sony Trinitron set as a gainfully-employed adult in the late 1980s, the need for all of that had gone away.
