This is a great thread. Thanks, JJ90!
I remember way way back in maybe 1999, the lessons had wav files, not videos. Videos would be way too big for dial up to transfer. The wav files had to be 8 bit, really small, and they sounded like they had been sent over AM radio. Then I heard about these new smaller better audio files. They were called "mp3 files" but you had to get "mp3 player software" to play them. You couldn't play them without downloading the mp3 player software.
I had to make a big decision. Should we go with this new "mp3 file?" Would it really catch on? Of course we did go with it, and of course it did catch on. It sounds silly now but at the time it was kind of risky.
