Well, there were magazines. Nintendo Power started pretty late in the 80s, but it was also I think the first place I heard about the minus worlds.

Hey, I was the guy that submitted the trick to Nintendo Power! A friend of a friend showed it to me after school and I immediately mailed it in to the magazine. Nintendo Power Agent #826.

Ok. To be clear, there were video game magazines before Nintendo Power (C&VG, for eg. Also, more obscure, but Nintendo's own predecessor the Nintendo Fun Club newsletter) and they played a significant role in spreading this info. The kid with the magazine sub was king of the playground, basically.

I was just stating my experience there.
