These days, most of us (including myself) take sampling for granted. We have our MPCs and MASCHINEs sitting right in front of us, and it's just a matter of dragging and dropping a file and you're good to go.
But that wasn't always the case. In addition to technically being more "work" to get the audio into your own track, early sampling was often "lifted" from copyrighted material, causing a firestorm of legal battles between content owners and those using their audio.
This video is a great look into where the sampling world was back in 1988, both legally and technically. Also, I'm pretty sure that's a young Saul Goodman at the 7:45 mark.
