In the 80's, rural America was copying cassettes for video and music at home. You could go to flea markets and buy copied products but many homes had tech to record/duplicate.
And then it got wild with cheap media for CD-ROM and DVD duplication just as Napster and other services along with the proliferation of internet connectivity.
In elementary school we made and traded mix tapes of songs from the radio. We rarely traded duped video cassettes.
