It is a shame that so much history has been lost. I remember interviewing Ralph Baer (RIP) known as the father of video games (he created the brown box in the 50s, I believe, it was very much Pong like) as well as working with Nolan Bushnell for some movie some former friends made (I helped them bring in almost 10 personalities for that event).
Sad to think that only Bushnell is alive now out of the ones I worked with.
Just shows life can go so quickly. Enjoy it while we can.
