It's cool that folks around the world are enjoying the Mac intro video. Where did it come from? The intro took place at the 1984 Apple shareholders' meeting, which was re-broadcast on public TV shortly after it happened. The re-broadcast was required because the meeting was full, so some shareholders couldn't get in, a potentially prickly legal situation. When the meeting was broadcast, I taped it on my home Betamax machine. It never occurred to me that it was so rare, or I would have tried to get it digitized years ago.
In the comments for the story, somebody asked for a digital copy. I said I didn't know of one, but that I would happy to lend the tape to anyone who could digitize it. Several people offered, but were ultimately scared off by the prospect of converting and cleaning up a 20-year-old Betamax tape. Then I heard from majo, who proceeded undaunted, sacrificing his time and servers, and now here we are. He's working on the rest of the tape now, and more clips and eventually the whole tape are forthcoming.
So, if you live long enough, you too can get worldwide publicity for never throwing anything away. ;-)
