Usually YT channels are per creator so it’s usually the same vein of content. But TV has channels from many sources and it’s a manually curated list of content.
I was referring to the same way of aggregating content. TV is old and we don’t need a 1 month program of planned content I guess because everything is on-demand but still. Being able to make a specialty like curated channel and share it to watch it like TV might be a thing.
