Logos on TV sets/monitors

[crt89]

This may be a dumb question and not sure what forum is best but.

Have you ever noticed how some TV sets have little emblems in the corner that show what's supported? Like they might have the Dolby symbol or Digital TV symbol. I wonder why that is that some do and others don't? I don't remember CRTs doing this as much although my Sylvania does say SDTV and Dolby Digital on it. My Sony VCR/DVD has logos on it too about supported things.

I even remember Apple doing something similar to this on some of their computers in the early 90s, I think it was only the Color Classic and Color Classic II that did. They had the QuickTime logo in the corner for some reason.
