Trying to distance this from the Logie Baird debate....
My understanding is that the NTSC was a branch of the NPL at Teddington. The
UK rejected the results of their deliberations as inadequate, and quietly
abandoned the whole idea until the Germans (primarily) came up with
PAL.Meanwhile RCA took on the NTSC system, and implemented it as the only
available system, despite the same concerns over quality.

> It's true. PAL has 625 lines of resolution, compared to 525 for NTSC, so
the resolution is better. Not that either ever really achieved their full
theoretical resolution. Especially on 1/2-inch consumer-level VHS
videotape. Many US TV sets had more like 250 lines (pixels). The big
difference is that NTSC codes color as the absolute phase of the color
subcarrier, while PAL uses the frame-to-frame difference, so PAL color is
far more robust. The Europeans, being the followers in color TV, had the
opportunity to improve upon NTSC.
