English NTSC TV's.

[dr.ido]

I think Sony were among the first with multi-standard with their KX-20PS1, KX-27PS1 and their various cube monitors. They all (at least in the versions sold/found here in Australia) supports PAL, NTSC and even SECAM. Of course these were high end models - multistandard didn't become a standard feature in lower end sets until much later. Even then Sony lead the way. I've got a basic low end Sony 14" set from around 1990 that does PAL/NTSC (probably not SECAM) when most similar sets from other manufacturers were still PAL only.

When PlayStation and DVD became a thing everyone here needed a multistandard TV. They may not know or care what PAL/NTSC are, but they noticed when their imported games/DVD movies didn't play in color. Official local releases are all PAL, but US imports are obviously NTSC as are almost all bootlegs and pirate copies (despite usually coming from parts of Asia that use PAL).
