This is a pretty good documentary by the british Discovery Channel about the beginnings of computer games. It covers the early 70s with the rise of Atari right up to the big crash of the videogame market in the 80s. From that point on, it becomes pretty one-sided by only covering Miyamoto (the inventor of Mario and Zelda) and Nintendo. Anyway, it's still an excellent documentary thanks to its accurate way of dealing with historical facts.
