John Logie Baird is often considered to be the inventor of television, but not of television as we know it. His mechanical television is a remarkable invention for its simplicity, but as you'll soon see, it would never have been all that practical.

The Technology Connections YouTube channel did a really good video on this and the mechanical TV: https://youtu.be/v5OANXk-6-w

Came here to say “video or it didn’t happen”. Was not disappointed. Terrific explainer, thanks for posting.

It seemed odd not to use a rotating cylinder rather than a disc, for parallel rather than curved scan lines. The cylinder could have become a tape, which would have reduced the size of the apparatus, although not as sturdy. /end steampunk mad inventor daydream

I just fell down the rabbit hole of Broadcast Mechanical Television... very interesting stuff!

I’m still not quite sure how the broadcast tech worked for the individual scan lines - I wonder if it was similar to later TV signals, or completely different?

Here is an excellent in-depth explanation of the concept from one of my favorite educational YouTube channels - Technology Connections: https://youtu.be/v5OANXk-6-w

I just watched that and have to agree, an excellent in-depth explanation it was indeed, with a lovely demonstration.
