Information:  - Atari is a corporate and brand name owned by several entities since its inception in 1972, currently by Atari Interactive, a subsidiary of the French publisher Atari, SA (ASA). The original Atari, Inc. founded in 1972 by Nolan Bushnell and Ted Dabney was a pioneer in arcade games, home video game consoles, and home computers. The company's products, such as "Pong" and the Atari 2600, helped define the electronic entertainment industry from the 1970s to the mid-1980s.  - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. 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. Some theorists categorize video games as an art form, but this designation is controversial.  - The Atari 2600 (or Atari VCS before 1982) is a home video game console by Atari, Inc. Released on September 11, 1977, it is credited with popularizing the use of microprocessor-based hardware and ROM cartridges containing game code, a format first used with the Fairchild Channel F video game console in 1976. This format contrasts with the older model of having non-microprocessor dedicated hardware, which could only play the games that were physically built into the unit.  - Night Stalker is an action shooting video game for the Intellivision console .  - The Intellivision is a home video game console released by Mattel Electronics in 1979.
