Since I’ve kinda tired of having to explain this every time someone asks, I’m now making a nice, hopefully somewhat big post on it.
“BS”, in Japan, is a term which predates the Satellaview, and came around during the origins of/early times of Satellite-Transferred programming in Japan.
There doesn’t necessarily have to be any particular rule for what could have “BS” tagged on it, except that it must have been “Broadcasted” from a Satellite. The term, after all, is an abbreviation for “Broadcasting Satellite”.
To bring the point in further, quite a LOT of content in Japan has “BS” versions. I’ve picked out a bit of something which may give a bit of a chuckle, but also some insight into what was shown, and how long these services have been around…
… Yeah, I picked a segment of a 1988 Ninja Turtles episode.
Surely the overseas visitors are LOLing now. No more of this, I’m already looking rather goofy.
… ah, I miss this show.
