@Jezz: Hi Jezz, Clearly there is a complex history when it comes to creating anything but it is COMMON knowledge that Nolan Bushnell is the creator/inventor of PONG. He holds the patent. Before Pong there was the Brown Box, Magnavox Odyssey invented by Ralph Baer which did offer a paddle and ball game. And yes, Nolan has repeated the story many times about how he saw Ralph's Magnavox Odyssey game, which needed much improvement and with Al Alcorn created PONG as we know it. It is no doubt that Ralph Baer is the creator of The Video Game (some would argue it's Steve Russell who programmed Space War) and without him PONG as we know it may never have seen the light of day. Even the Wikipedia link you attached to Ralph does not quote him as being the inventor of Pong but the Nolan Bushnell page does share the story of how PONG was born. At the end of the they are all equally fascinating.
We are always reaching out to get more of the dev story. Those efforts are always happening. As Charles mentioned this is a high level overview really for the geek not the dev. But like I said. "We are working on it"
