Computer Space was followed in 1972 by the Magnavox Odyssey, the first home console.
Modeled after a late 1960s prototype console developed by Ralph H.
As of 2015, video games generated sales of USD 74 billion annually worldwide, and were the third-largest segment in the U. entertainment market, behind broadcast and cable TV.
Early games used interactive electronic devices with various display formats. Inspired by radar display technology, it consisted of an analog device that allowed a user to control a vector-drawn dot on the screen to simulate a missile being fired at targets, which were drawings fixed to the screen.
In common use a "PC game" refers to a form of media that involves a player interacting with a personal computer connected to a video monitor.
Personal computers are not dedicated game platforms, so there may be differences running the same game in different hardware, also the openness allows some features to developers like reduced software cost, increased flexibility, increased innovation, emulation, creation of modifications ("mods"), open hosting for online gaming (in which a person plays a video game with people who are in a different household) and others.
These platforms range from large mainframe computers to small handheld computing devices.
Specialized video games such as arcade games, in which the video game components are housed in a large, typically coin-operated chassis, while common in the 1980s in video arcades, have gradually declined due to the widespread availability of affordable home video game consoles (e.g., Play Station 4, Xbox One and Nintendo Wii U) and video games on desktop and laptop computers and smartphones.
The word video in video game traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images.
"Arcade game" generally refers to a game played on an even more specialized type of electronic device that is typically designed to play only one game and is encased in a special, large coin-operated cabinet which has one built-in console, controllers (joystick, buttons, etc.), a CRT screen, and audio amplifier and speakers.
Arcade games often have brightly painted logos and images relating to the theme of the game.
A "console game" is played on a specialized electronic device that connects to a common television set or composite video monitor, unlike PCs, which can run all sorts of computer programs, a console is a dedicated video game platform manufactured by a specific company.
Usually consoles only run games developed for it, or games from other platform made by the same company, but never games developed by its direct competitor, even if the same game is available on different platforms. Major console platforms include Xbox, Play Station, and Nintendo.
