What was the first video game ever created and how did its gameplay looked like?

Answer 1

In 1952, Alexander S. Douglas made the first computer game to use a digital graphical display, OXO (Noughts and Crosses), for the EDSAC computer. Tennis for Tworecreation In 1958, William Higinbotham made an interactive game named Tennis for Two for the Brookhaven National Laboratory's annual visitor's day. This display, funded by the U.S. Department of Energy, was meant to promote atomic power, and used an analog computer and the vector display system of an oscilloscope.[5][6] In 1961, MIT students Martin Graetz, Steve Russell, and Wayne Wiitanen created the game Spacewar! on a DEC PDP-1 computer which also used a vector display system.[1][6] The Magnavox Odyssey released in 1972

In 1966, Ralph Baer resumed work on an initial idea he had in 1951 to make an interactive game on a television set. In May of 1967, Baer and an associate created the first video game to use a raster-scan display, which was also the first video game to be played on a regular television set.[7] The Brown Box, the last prototype of seven, was released in May 1972 by Magnavox under the name Odyssey. It was the first home video game console. In 1971, Bill Pitts and Hugh Tuck developed the first coin-operated computer game, Galaxy Game, at Stanford University using a DEC PDP-11/20 computer; only one unit was ever built (although it was later adapted to run up to eight games at once). Two months after its installation, Computer Space by Nolan Bushnell and Ted Dabney was released, which was the first coin-operated video game to be commercially sold (and the first widely available video game of any kind, predating The Odyssey by six months). Both games were variations on the vector display 1961 Spacewar!; however, Bushnell and Dabney's used an actual video display by having an actual television set in the cabinet. Pong, also by Bushnell and Dabney, was not released until 1972 - a year after Computer Space, and also using the same television set design as Computer Space. Baer was involved in court battles over patents that spanned the 1970s and 1980s. These trials defined a video game as an apparatus that displays games by manipulating the video display signal of the raster equipment: a television set, a monitor, etc. The previous computer games did not use a video display, so did not qualify as such in the courts. On February 13, 2006 Baer was given a National Medal of Technology by President George W. Bush in honor of his "groundbreaking and pioneering creation, development and commercialization of interactive Video Games.
