Just a nitpick: analog NTSC was roughly 480i at (just under) 30 FPS. The latter is significant, as 3:2 pulldown (as would have been necessary if the station's cameras were scanning at 24 FPS) would have introduced judder and made tracking even harder. To its credit, interlacing also improved motion clarity at the expense of loss of detail, but whether that's a net benefit ultimately amounts to a matter of preference.
