No, cable was specifically created to deliver broadcast to those that could not receive it[0]. Those many more channels came some time later

Maybe revisionist but what most people think of as "cable" was broadband cable (maybe DirecTV, launched 1994) with lots of commercial channels. They don't think of having a 12 foot antenna scouring the sky for signals.
There was certainly some earlier cable, e.g. HBO, if you could pickup broadcast, that predated channels like CNN.
