I was actually thinking about this recently... Pre-streaming, pre-"we mail you DVDs" you were limited to what was on TV (cable if you were lucky) and whatever was at your local independent video store. Depending on what size town you lived in, that was a pretty limiting factor. In Asheville 25 years ago, we had two pretty good independent movie shops. Both had a modest selection of foreign films. But once you had exhausted them...
Nowadays, you are pretty much only limited by your awareness and imagination. It's rather extraordinary.
