CSPAN

How do most people watch C-SPAN now? Old receiver used as a positioner and analog video as a bonus or some kind of A/B switch setup? I'd be grateful if somebody could give a history lesson about the channel or the days of analog transmissions in general, because I'm entirely out of the loop.
