Football, Atari Inc., 1978
Football was the first true video sports game. It was created by Dave Stubben. Its development originally began as a game called "X's and O's" by Steve Bristow in late 1973. The project was shelved for years until the Atari figured out a way to break out from the limits of the single-screen game displays of the time. Football introduced "scrolling" video game displays to the world, allowing games to take place on playfields larger than the monitor on which they were displayed. Later-on Atari has made a lot of money for its patent for scrolling video game displays that rose from Football. Football was also the first game to feature the track ball.
