First PAL sets , S-Pal, produced "Venetian blinds" with Dif Phase errors , later PAL-D solved this but lost half vert chroma resolution in the process.
Early NTSC subject to Diff phase in Hi-Lvl Mod transmitters & microwave links. By early 1960s, these problems solved
Australia should have adopted SMPTE 525/60 in the late 1940s with corresponding channel assignments that didn't violate the FM band (stupid) & color in the early 1960s (Japan,Canada, Philippines)--Compatibility with Asia (manufacturing) Pacific Rim/US .
Many countries in caribbean, Americas - some European colonies - chose NTSC for convenience, economy of scale, compatibility
