Answer:
Computer scientists began building rudimentary games and simulations on mainframe computers in the 1950s and 1960s, with MIT's Spacewar! in 1962 being one of the first such games to be played with a video display. The first consumer-ready video game hardware arrived in the early 1970s, with the Magnavox Odyssey, the first home video game system, and the first arcade video games from Atari, Computer Space and Pong, the latter of which was later transformed into a home console version. Pong's success in arcades and at home prompted numerous firms to create clones of the game, resulting in a market contraction in 1978 owing to oversaturation and a lack of innovation.
