In 1971, Nutting Associates released Computer Space, the world's first coin-operated video arcade game. It was followed swiftly by games such as Atari's Pong and Breakout, landmarks in the early phase of the video game revolution. In After Burner, players control an F-14 Tomcat jet and must destroy enemy fighters with missiles during 18 game stages. The game was later ported to many home consoles, including the Nintendo Entertainment System and the Sega Master System. The game gained popularity in 1991 when the character John Connor was shown playing this game in the movie Terminator 2: Judgment Day. The game was followed by two sequels: After Burner II in 1987, and After Burner Climax in 2006.
