We had radio shows that transmitted software over the airwaves... still think that was incredible! It wasn't very reliable, though (and not very fun to listen to).
Unless you bought a c64 and realized you can't use any old tape recorder, but had to buy a proprietary (albeit much more reliable) commodore tape deck.
I had one of those. Then I got a 1541 disk drive as a gift one year. Ah, the angry look on my dad's face in the wee hours of the morning having been awakened by that obnoxious clacking sound caused by the disk drive encryption methods of the day.
