Electronic game in the context of Computer game

A video game, computer game, or simply game, is an electronic game that involves interaction with a user interface or input device (such as a joystick, controller, keyboard, or motion sensing 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 (e.g., haptic technology that provides tactile sensations). Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming.

Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and computer games (which includes LAN games, online games, and browser games). More recently, the video game industry has expanded onto mobile gaming through mobile devices (such as smartphones and tablet computers), virtual and augmented reality systems, and remote cloud gaming. Video games are also classified into a wide range of genres based on their style of gameplay and target audience.

Handheld electronic games are interactive electronic games, often miniaturized versions of video games, that are played on portable handheld devices, known as handheld game consoles, whose controls, display and speakers are all part of a single unit. Rather than a general-purpose screen made up of a grid of small pixels, they usually have custom displays designed to play one game. This simplicity means they can be made as small as a smartwatch, and sometimes are. The visual output of these games can range from a few small light bulbs or LED lights to calculator-like alphanumerical screens; later these were mostly displaced by liquid crystal and vacuum fluorescent display screens with detailed images and in the case of VFD games, color. Handhelds' popularity was at its peak from the late 1970s into the early 1990s before declining. They are the precursors to the handheld game console.

An audio game is an electronic game played on a device such as a personal computer. It is similar to a video game save that there is audible and tactile feedback but not visual.

Audio games originally started out as 'blind accessible'-games and were developed mostly by amateurs and blind programmers.But more and more people are showing interest in audio games, ranging from sound artists, game accessibility researchers, mobile game developers and mainstream video gamers. Most audio games run on a personal computer platform, although there are a few audio games for handhelds and video game consoles. Audio games feature the same variety of genres as video games, such as adventure games, racing games, etc.

A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. The PRNG-generated sequence is not truly random, because it is completely determined by an initial value, called the PRNG's seed (which may include truly random values). Although sequences that are closer to truly random can be generated using hardware random number generators, pseudorandom number generators are important in practice for their speed in number generation and their reproducibility.

PRNGs are central in applications such as simulations (e.g. for the Monte Carlo method), electronic games (e.g. for procedural generation), and cryptography. Cryptographic applications require the output not to be predictable from earlier outputs, and more elaborate algorithms, which do not inherit the linearity of simpler PRNGs, are needed.

The history of Nintendo, a Japanese video game company based in Kyoto, starts in 1889 when Fusajiro Yamauchi founded "Yamauchi Nintendo", a producer of hanafuda playing cards. Sekiryo Kaneda was company president from 1929 to 1949. His successor Hiroshi Yamauchi had Nintendo producing toys like the Ultra Hand, and video games, including arcade games, the Color TV-Game series of home game consoles (1977—83), and the Game & Watch series of handheld electronic games (1980—86).

Shigeru Miyamoto designed Donkey Kong (1981) for arcades: Nintendo's first international hit game, and origin of the company's mascot, Mario. After the American video game crash of 1983, Nintendo filled a market gap there by releasing their Japanese Famicom home console (1983) as the Nintendo Entertainment System (NES) in 1985. Miyamoto and Takashi Tezuka's innovative Famicom/NES titles, Super Mario Bros. and The Legend of Zelda, greatly influenced gaming. The Game Boy handheld console (1989) and the Super Nintendo Entertainment System home console (1990) were successful, yet Nintendo had an intense business rivalry with Sega's consoles. The Virtual Boy (1995), a portable console with stereoscopic 3D graphics, was a critical and financial failure. With the Nintendo 64 (1996), Nintendo began making games with fully-3D computer graphics. The Pokémon media franchise, partially owned by Nintendo, has been a worldwide hit since 1996.

A text game or text-based game is an electronic game that uses a text-based user interface, that is, the user interface employs a set of encodable characters, such as ASCII, instead of bitmap or vector graphics.

Text-based games have been well documented since at least the 1960s, when teleprinters were interlaced with mainframe computers as a form of input, where the output was printed on paper. With that, notable titles were developed for those computers using the sprinter in the 1960s and 1970s and more numerous game titles have been developed for other video terminals since at least the mid-1970s, having reached their peak popularity in that decade and the 1980s, and continued as early online games into the mid-1990s.

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 early 1970s, when arcade video games, gaming consoles and personal 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 personal computer and arcade video games in the 1970s, followed by Pong and the beginning of the first generation of video game consoles with the Magnavox Odyssey in 1972. 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.

Following the 1947 invention of the cathode-ray tube amusement device—the earliest known interactive electronic game as well as the first to use an electronic display—the first true video games were created in the early 1950s. Initially created as technology demonstrations, such as the Bertie the Brain and Nimrod computers in 1950 and 1951, video games also became the purview of academic research. A series of games, generally simulating real-world board games, were created at various research institutions to explore programming, human–computer interaction, and computer algorithms. These include Sandy Douglas' OXO, Christopher Strachey's Checkers, and Stanley Gill's Sheep and Gates (all 1952), the first software-based games to incorporate a cathode-ray tube display, and several chess and checkers programs.

In-game advertising (IGA) is advertising in electronic games. IGA differs from advergames, which refers to games specifically made to advertise a product. The IGA industry is large and growing.

In-game advertising generated $34 million in 2004, $56 million in 2005, $80 million in 2006,and $295 million in 2007.In 2009, spending on IGA was estimated to reach $699 million USD, $1 billion by 2014 and according to Forbes is anticipated to grow to $7.2 billion by 2016.
