The screen on my mobile phone is less than an inch square. I'm fairly
sure they don't make CRTs that small.

HDTV broadcasts (ATSC here in the US and Hi-Definition cable channels)
are all in widescreen. I seem to remember when visiting the UK a few
years ago that the broadcast signals we watched there also tended to be
in widescreen. In fact, it seemed more popular than 4:3 broadcasts from
what I saw.

Untrue. I watch QI, Spooks, Spooks:Code 9, and a few other shows out of
the UK that are recorded by friends in the UK for me. They're all in
widescreen.

I remember reading/hearing about a proposed new CRT technology where
the idea was that instead of having just one cathode ray for the entire
screen (ok, three rays, one for each color component), you would have
one ray (well, three rays) per pixel.
The advantage of this is that the cathode ray emitters can be made very
small and simple (as they don't require the controlling magnets) and they
can be brought very close to the screen. Thus you basically get a very
thin and relatively lightweigth screen with all the advantages of CRT.
(Of course you also get some of the disadvantages of LCD, eg. the fixed
resolution.)

So, should I conclude that, in a world of sheep, 16:9 creen is better than 4:3 ?
A world of sheep, tranquil herbivores... opposed to a fierce world of predators.
Just follow, no initiative!
Work dumb, Survive, Buy, Consum. No question.
Yes... seems to fit the requirements.

You forget: it's heavy and taking a lot of room (and hard worker to move them!)
From a seller point of view, a CRT space is happily replaced by 4 to 10 LCD in the
stocking room. In the display room, LCD give you back 2 square meter per linear meter
of
exposition. More stock, more room... who cares!
So, do the math... less for storage, less investement for showing... even if the
colours
are ugly, the display is horrible, the market has an offer no-seller could refuse with
LCD. (and who care about the consumer... he will believe the marketing!)
Still waiting for oled... sadly.

Not really:

I also read of one where you had two guns, one just before the phospher
screen and one behind it, pointing up, with a mag field that curved the beam
to hit the sides of the screen. Apparently a yellow/purple combination can
give you almost as good color as tri-color beams. If you wanted a very
large flat CRT, that's how you could do it.
I don't think the idea ever developed into a commercial product, probably
*because* LCDs got there first.
