Actually 4:3 and 480 (interlaced) lines.   Aspect ratios are always
expressed *as* ratios (":" not "x") and the width is always given
first.  A 3:4 screen would have a very different shape than a 4:3 one.
This becomes important when comparing different aspect ratios,
especially between TV, where the terms 4:3 and 16:9 tend to be used a
lot, and film, where the second value in all ratios is "1".  (As in
2.60:1, 2.35:1, 1.85:1, 1.66:1 - it is easy in all cases to understand
how wide each is in relation to the others.  4:3 and 16:9 are,
respectively, about 1.33:1 and 1.78:1

And while an NTSC broadcast signal is made up of 525 horizontal lines,
the number actually devoted to the image is 480.  Other data including
closed captioning information is carried in the remaining lines.
