Early history of video games
Throughout the rest of the 1960s, digital computer games were created by increasingly numerous programmers and sometimes sold commercially in catalogs. As the audience for video games expanded to more than a few dozen research institutions with the falling cost of computers, and programming languages that would run on multiple types of computers were created, a wider variety of games began to be developed. Video games transitioned into a new era in the early 1970s with the launch of the commercial video game industry in 1971 with the display of the coin-operated arcade game "Galaxy Game" and the release of the first arcade video game "Computer Space", and then in 1972 with the release of the immensely successful arcade game "Pong" and the first home video game console, the Magnavox Odyssey, which launched the first generation of video game consoles.
Interactive movie
A LaserDisc video game is a video game that uses pre-recorded video (either live-action or animation) played from a LaserDisc, either as the entirety of the graphics, or as part of the graphics. The first arcade laserdisc game was Sega's "Astron Belt", an early third-person space combat rail shooter featuring live-action full-motion video footage (largely borrowed from a Japanese science fiction film) over which the player/enemy ships and laser fire are superimposed. Developed in 1982, the game's unveiling at the 1982 AMOA show in Chicago marked the beginning of LaserDisc fever in the videogame industry, and its release in Japan the following year marked the first commercial release of a LaserDisc game. However, its release in the United States was delayed due to several hardware and software bugs, by which time "Dragon's Lair" had beaten it to public release there.
