A video game, also known as a computer game or just a game, is an electronic game that involves interaction with a user interface or input device to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with audio complement delivered through speakers or headphones, and sometimes also with other types of sensory feedback. Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming.
The Electronic Delay Storage Automatic Calculator (EDSAC) was an early British computer. Inspired by John von Neumann's seminal First Draft of a Report on the EDVAC, the machine was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. EDSAC was the second electronic digital stored-program computer, after the Manchester Mark 1, to go into regular service.
Nim is a mathematical game of strategy in which two players take turns removing objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap or pile. Depending on the version being played, the goal of the game is either to avoid taking the last object or to take the last object.
The year 1951 in science and technology involved some significant events, listed below.
The Ferranti Mark 1, also known as the Manchester Electronic Computer in its sales literature, and thus sometimes called the Manchester Ferranti, was produced by British electrical engineering firm Ferranti Ltd. It was the world's first commercially available electronic general-purpose stored program digital computer.
Tennis for Two is a sports video game that simulates a game of tennis, and was one of the first games developed in the early history of video games. American physicist William Higinbotham designed the game in 1958 for display at the Brookhaven National Laboratory's annual public exhibition after learning that the government research institution's Donner Model 30 analog computer could simulate trajectories with wind resistance. He designed the game within a few hours, after which he and technician Robert V. Dvorak built it over a period of three weeks. The game was displayed on an oscilloscope and played with two custom aluminum controllers. Its visuals show a representation of a tennis court viewed from the side, and players adjust the angle of their shots with a knob on their controller and try to hit the ball over the net by pressing a button.
Christopher S. Strachey was a British computer scientist. He was one of the founders of denotational semantics, and a pioneer in programming language design and computer time-sharing. He has also been credited as possibly being the first developer of a video game and for coining terms such as polymorphism and referential transparency that are still widely used by developers today. He was a member of the Strachey family, prominent in government, arts, administration, and academia.
OXO is a video game developed by A S Douglas in 1952 which simulates a game of noughts and crosses (tic-tac-toe). It was one of the first games developed in the early history of video games. Douglas programmed the game as part of a thesis on human-computer interaction at the University of Cambridge.
An electronic game is a game that uses electronics to create an interactive system with which a player can play. Video games are the most common form today, and for this reason the two terms are often used interchangeably. There are other common forms of electronic games, including handheld electronic games, standalone arcade game systems, and exclusively non-visual products.
Mary Lee Berners-Lee was an English mathematician and computer scientist who worked in a team that developed programs in the Department of Computer Science, University of Manchester Mark 1, Ferranti Mark 1 and Mark 1 Star computers. She was the mother of Sir Tim Berners-Lee, the inventor of the World Wide Web, and Mike Berners-Lee, an English researcher and writer on greenhouse gases.
A gaming computer, also known as a gaming PC, is a specialized personal computer designed for playing PC games at high standards. They typically differ from mainstream personal computers by using high-performance graphics cards, a high core-count CPU with higher raw performance and higher-performance RAM. Gaming PCs are also used for other demanding tasks such as video editing.
The history of video games spans a period of time between the invention of the first electronic games and today, covering many inventions and developments. Video gaming reached mainstream popularity in the 1970s and 1980s, when arcade video games, gaming consoles and home computer games were introduced to the general public. Since then, video gaming has become a popular form of entertainment and a part of modern culture in most parts of the world. The early history of video games, therefore, covers the period of time between the first interactive electronic game with an electronic display in 1947, the first true video games in the early 1950s, and the rise of early arcade video games in the 1970s. During this time there was a wide range of devices and inventions corresponding with large advances in computing technology, and the actual first video game is dependent on the definition of "video game" used.
The Manchester Mark 1 was one of the earliest stored-program computers, developed at the Victoria University of Manchester, England from the Manchester Baby. Work began in August 1948, and the first version was operational by April 1949; a program written to search for Mersenne primes ran error-free for nine hours on the night of 16/17 June 1949.
Electro-mechanical games are types of arcade games that operate on a combination of some electronic circuitry and mechanical actions from the player to move items contained within the game's cabinet. Some of these were early light gun games using light-sensitive sensors on targets to register hits, while others were simulation games such as driving games, combat flight simulators and sports games. EM games were popular in amusement arcades from the late 1940s up until the 1970s, serving as alternatives to pinball machines, which had been stigmatized as games of chance during that period. EM games lost popularity in the 1970s, as arcade video games had emerged to replace them in addition to newer pinball machines designed as games of skill.
Bertie the Brain is one of the first games developed in the early history of video games. It was built in Toronto by Josef Kates for the 1950 Canadian National Exhibition. The four meter tall computer allowed exhibition attendees to play a game of tic-tac-toe against an artificial intelligence. The player entered a move on a keypad in the form of a three-by-three grid, and the game played out on a grid of lights overhead. The machine had an adjustable difficulty level. After two weeks on display by Rogers Majestic, the machine was disassembled at the end of the exhibition and largely forgotten as a curiosity.
The Nimatron was an electro-mechanical machine that played Nim. It was first exhibited in April–October 1940 by the Westinghouse Electric Corporation at the 1939-1940 New York World's Fair to entertain fair-goers. Conceived of some months prior by Edward Condon and built by Gerald L. Tawney and Willard A. Derr, the device was a non-programmable digital computer composed of electro-mechanical relays which could respond to players' choices in the game in a dozen different patterns. The machine, which weighed over a metric ton, displayed four lines of seven light bulbs both in front of the player and on four sides of an overhead cube. Players alternated turns with the machine in removing one or more lights from one of the rows until the lights were all extinguished. The calculations were purposely delayed to give the illusion that the machine was considering moves, and winners received a token.
Dietrich Gunther Prinz was a computer science pioneer, notable for his work on early British computers at Ferranti, and in particular for developing the first limited chess program in 1951.
Marienbad was a 1962 Polish puzzle mainframe game created by Elwro engineer Witold Podgórski in Wrocław, Poland for its Odra 1003. It was an adaption of the logic game nim. Inspired by the discussion in the magazine Przekrój of a variant of nim in the 1961 film Last Year at Marienbad, named "Marienbad" by the magazine, Podgórski programmed the game for the in-development 1003 mainframe, released in 1963. The game had players opposing the computer in alternating rounds of removing matches from a set, with the last player to take a match the loser. As the computer always played the optimal moves, it was essentially unbeatable.
Turochamp is a chess program developed by Alan Turing and David Champernowne in 1948. It was created as part of research by the pair into computer science and machine learning. Turochamp is capable of playing an entire chess game against a human player at a low level of play by calculating all potential moves and all potential player moves in response, as well as some further moves it deems considerable. It then assigns point values to each game state, and selects the move resulting in the highest point value.
An arcade game or coin-op game is a coin-operated entertainment machine typically installed in public businesses such as restaurants, bars and amusement arcades. Most arcade games are presented as primarily games of skill and include arcade video games, pinball machines, electro-mechanical games, redemption games or merchandisers.
