Did You Know...
...that the video game, Pong, was invented by a guy who graduated at the bottom of his engineering class? Nolan Bushnell spent more time running the games at a local amusement park than he did on his studies at the University of Utah. His dreams of working for Disney's amusement empire were dashed when the company wouldn't hire him. Taking a boring job, Nolan daydreamed about electronic versions of popular games. He invented Pong, the first video game, and went on to found Atari Co.
