Actually the first time a picture was captured and shown predates
the telephone by many years.
It was the old spinning wheel type, and had the wheels on a common
shaft with the image being picked up by device behind the lens in
front of the first disk, and then amplified to turn on a light
on the connected disk. Not TV as we know it, but neither was
the first telephone invented by Bell/Gray [take your pick on that
controversy]

I saw diagrams of the original device on a shaft a jillion years
ago. And when I was in college I found a book on TV that was
printed in the late 1920s - when the only device out there
was the spinning disk.
Then there was John Logie Baird who invented/produced the first
video disk back in about 1929.
And as I recall his transmitted system used 3 signals. One for
audio, one for turning the light on and off, and another for
keeping the spinning disks in sync.
TV is much older than most people think/assume.
