Killer app in the context of "Second generation of console video gaming"

In the history of video games, the second-generation era refers to computer and video games, video game consoles, and handheld video game consoles available from 1976 to 1992. Notable platforms of the second generation include the Fairchild Channel F, Atari 2600, Intellivision, Odyssey 2, and ColecoVision. The generation began in November 1976 with the release of the Fairchild Channel F. This was followed by the Atari 2600 in 1977, Magnavox Odyssey² in 1978, Intellivision in 1979 and then the Emerson Arcadia 2001, ColecoVision, Atari 5200, and Vectrex, all in 1982. By the end of the era, there were over 15 different consoles. It coincided with, and was partly fueled by, the golden age of arcade video games. The generation also included the entry of handheld consoles, chiefly led by Nintendo’s foray into gaming led by the Blue Ocean philosophy of Gunpei Yokoi and the release of the Game & Watch in 1980. This peak era of popularity and innovation for the medium resulted in many games for second generation home consoles being ports of arcade games. Space Invaders, the first "killer app" arcade game to be ported, was released in 1980 for the Atari 2600, though earlier Atari-published arcade games were ported to the 2600 previously. Coleco packaged Nintendo's Donkey Kong with the ColecoVision when it was released in August 1982.

Built-in games, like those from the first generation, saw limited use during this era. Though the first generation Magnavox Odyssey had put games on cartridge-like circuit cards, the games had limited functionality and required TV screen overlays and other accessories to be fully functional. More advanced cartridges, which contained the entire game experience, were developed for the Fairchild Channel F, and most video game systems adopted similar technology. The first system of the generation and some others, such as the RCA Studio II, still came with built-in games while also being able to use cartridges. The popularity of game cartridges grew after the release of the Atari 2600. From the late 1970s to the mid-1990s, most home video game systems used cartridges until the technology was replaced by optical discs. The Fairchild Channel F was also the first console to use a microprocessor, which was the driving technology that allowed the consoles to use cartridges. Other technology such as screen resolution, color graphics, audio, and AI simulation was also improved during this era. The generation also saw the first handheld game cartridge system, the Microvision, which was released by toy company Milton Bradley in 1979.

Star Raiders is a space combat simulator video game created by Doug Neubauer and published in 1980 by Atari, Inc. Originally released for the Atari 400/800 computers, Star Raiders was later ported to the Atari 2600, Atari 5200, and Atari ST. The player assumes the role of a starship fighter pilot, who must protect starbases from invading forces called Zylons. Piloting and combat are shown in the 3D cockpit view, while a 2D galactic map shows the state of the Zylon invasion. Neubauer made the game in his spare time at Atari, inspired by contemporary media such as Battlestar Galactica and Star Wars, as well as the 1971 mainframe game Star Trek.

Star Raiders became one of the most successful games on Atari's 400 and 800 computers, and their first killer app. It influenced space combat games such as Elite (1984) and Wing Commander (1990), as well as spawning an official sequel and a 2011 remake. Star Raiders was included in a list of ten games that were submitted as a game canon to the Library of Congress in 2007.
