The origins of the video game go back to the 1950s, when shortly after the appearance of the first electronic computers after the end of the Second World War, the first attempts were carried out by implementing programs of a playful nature. Thus, the NIM (1951) or the OXO (1952), electronic games that can not be called video games were created, and Tennis for Two (1958) or Spacewar! (1962), authentic pioneers of the genre. All of them were still prototypes, very simple and experimental games that did not come to market, among other things, because they worked on machines that were only available at universities or research institutes.
It would not be until the decade of the 70s, with the decline in manufacturing costs, the first recreational machines and the first video games directed to the great public appeared. Titles such as Computer Space (1971) or Pong (1972), from Atari, inaugurated the first recreational machines built to the effect, which worked with coins. Shortly after the video games would come to households thanks to the domestic consoles, the first of which was the Magnavox Odyssey (1972), and later the successful ATARI 2600 or VCS (from 1977), with its system of interchangeable cartridges. At that time Arcade machines began to becomes common in recreational bars and salons, an expansion due in part to a Matamarciane who reached great popularity, the Space Invaders (1978). Other games that marked this first time were Galaxian (1979), Asteroids (1979) or Pac-Man (1980).
