In marketing terminology, a killer application (commonly shortened to killer app) is any computer program that is so necessary or desirable that it proves the core value of some larger technology, such as computer hardware, gaming console, software, a programming language, software platform, or an operating system. In other words, consumers would buy the (usually expensive) hardware just to run that application. A killer app can substantially increase sales of the platform on which it runs.
One of the first examples of a killer application is generally agreed to be the VisiCalc spreadsheet for the Apple II series. Because it was not available on other computers for 12 months, people purchased the $100 software first, then the $2000 Apple they needed to run it. BYTE wrote in 1980, "VisiCalc is the first program available on a microcomputer that has been responsible for sales of entire systems", while Creative Computing's VisiCalc review was subtitled "reason enough for owning a computer". Another is WordStar, the most popular word processor during much of the 1980s. The next example is another spreadsheet, Lotus 1-2-3. Sales of IBM's Personal computer increased rapidly a few months after Lotus 1-2-3's release. Once the Internet became more widely available to consumers, email was seen as a killer app that drove people to purchase computers, even though email is a genre of applications rather than a single "app." The definition of "killer app" came up during Bill Gates's questioning in the United States v. Microsoft antitrust suit. Bill Gates had written an email in which he described Internet Explorer as a killer app. In the questioning, he said that the term meant "a popular application", and did not connote an application that would fuel sales of a larger product or one that would supplant its competition, as the Microsoft Computer Dictionary defined it.
Selected applications for computer systems
The term has also been applied to computer and video games that cause consumers to buy a particular video game console or gaming hardware over a competing one. Examples of a video game killer applications are:
- The first generally agreed example of a "killer app" in gaming is Space Invaders, released for arcades in 1978 and ported to the Atari VCS (Atari 2600) console in 1980, quadrupling sales of the then three-year-old Atari 2600 platform.
- Star Raiders, released in 1979 on cartridge for the Atari 8-bit computer, was considered to be a "killer app" for a computer platform.
- Donkey Kong was the killer app for the ColecoVision console in 1982.
- The video gaming website GameTrailers considers the Super Mario Bros. games to be the killer app for nearly all Nintendo home consoles, Tetris as the killer app for the Game Boy, Grand Theft Auto III for the PlayStation 2, Super Smash Bros. Melee for the GameCube, and Wii Sports for the Nintendo Wii.
- Computer Gaming World stated that The Legend of Zelda on the Nintendo Entertainment System, Phantasy Star II on the Sega Genesis, and Far East of Eden for the NEC TurboGrafx-16 were killer apps for their consoles.
- Sonic the Hedgehog, released in 1991, was hailed as a killer app as it revived sales of the (by then) three-year-old Sega Mega Drive / Genesis.
- Myst and The 7th Guest, both released in 1993, are considered to be killer apps for their influence on CD-ROM drive sales, leading to widespread market adoption of the format.
- Final Fantasy VII is considered a "killer app" that the original PlayStation had along with Metal Gear Solid. These were immensely popular exclusives for the system. Earlier killer apps included Resident Evil, Tomb Raider, Gran Turismo and Crash Bandicoot.
- Pokémon Red and Blue would be classified a "killer app" for the seven-year-old Game Boy as a craze evolved around the series in the late 90s, and it was only available on that platform.
- Pokemon Gold and Silver were released at the height of the Pokemon craze alongside the Game Boy Color, and fueled the sales for the console all the way to the release of the Game Boy Advance two years later.
- GoldenEye 007, The Legend of Zelda: Ocarina of Time and Super Mario 64 are considered killer apps for the Nintendo 64, with Super Mario 64 being one of two launch titles for the console and the main factor behind the platform's initial success.
- Quake is considered the killer app for 3dfx's Voodoo Graphics 3D accelerator card for home computers.
- Halo and Gears of War are considered to be the killer apps for the Xbox, Xbox 360, and Xbox One.
