Fascinating article on how Atari pioneered box art:
"The original Atari featured a wealth of games with box art that was quite a bit more imaginative than the “grizzled man holding a gun” template that’s so popular today. The concept of playing a video game in your house, on your television, was still in its infancy in the late 1970s, and Atari needed a way to market its games. One solution was to commission intricately detailed covers that sold the idea of a game much better than any simple screenshot could."
