The IBM Centennial Film.

I've done some work for IBM and it was some of the most rewarding work I've ever done.  The people I worked with were very bright and very good at what they did.  Specifically, I worked with the Entry Systems Division (aka the PC group) and the Advanced Technology Group (aka Unix workstations).  You probably have a fair impression of what IBM has accomplished in the past 100 years, but this wonderfully produced film might remind you of a few things.
