(Makeshift) History
Anime made it's way from Japan to the United States and elsewhere via VHS tapes, subtitled by fans and copied by other fans. VHS degradation made later generation copies harder to read, and the limited interest in anime kept the concerns of IP theft to a very minimum.
Somewhere in the mid 90s, VivoActive videos of anime were passed around, but they were about the size of a postage stamp. We don't really want to remember that era.
Jump ahead to the New Millennium, with faster internet speeds, larger hard-drives and such.
