The signals were not coupled, at least not in that way, and at least in NTSC. None of the bandwidth of the audio signal overlaps with the video signal. In fact, the audio signal was just a standard FM signal that you could tune into with a radio.
Maybe in those days they just played a loud noise that didn’t actually replace the sound and that was cheaper than setting something up with bandpass filters to mute it for a moment.
I suppose you could view it like that lol. I’m not sure if modern video formats found a way to compress audio and video together. My guess is not because they’re so inherently different. Films (like ya know, movies on film) had the audio on the film besides the frames.

wow, so today when we have podcasts that are also available as long youtube videos, we are in fact continuing a (single century) long tradition
