I have some questions and thoughts about roundies.

On a color roundie, you wouldn't be able to see the corners due to the shadow mask and other internals.

I believe that broadcasters would avoid putting anything important in the corners. Steve D might be able to elaborate on this, but I don't think they tried putting anything like icons in the corners 'til the 90s.

I recall back in the late'60's when rectangular color sets were starting to outsell roundies, our directors would still make sure pictures were framed so that nothing important was cut off on a home roundie color set. This was especially critical when producing commercials. After all there were thousands of round tube color sets in use well into the 80's.
