Why were old TV screens so small?

Early TV screens were small mainly because the technology back then had some restrictions.

The first TVs were kind of like machines and used a spinning disk to show pictures.

The screen size depended on how big this disk was, usually ranging from 5 to 15 inches diagonally.

Later on, they made electronic TVs that were better – clearer pictures and easier to make a lot of them.

These new ones took over from the old machines, making them outdated.

Also, those early TVs were big, and the size of the picture tube (CRT) limited how big the screen could be.

For example, the Octagon, one of the first TVs from General Electric in 1928, had a three-inch screen that used a spinning disc to show images.

So, the small screens in old TVs happened because of the technology of the time and the limits of the picture tubes.
