Space Race (video game)
Development of "Space Race" began soon after the founding of Atari in Summer 1972 under the name "Asteroid". Co-founders Nolan Bushnell and Ted Dabney had the initial idea for the game while developing the 1971 "Computer Space", the first arcade video game, but felt the more complicated "Computer Space" was a better first game. After leaving Nutting Associates and founding Atari in May 1972, Bushnell spent a few days designing "Asteroid", but soon had to drop the project to focus on running the company. After the release of "Pong", Atari's first game, development resumed on the title in Spring 1973. Dabney has claimed credit for the game's final design, though "Pong" designer Allan Alcorn has stated that he and Bushnell may have been involved as well. "Asteroid", codenamed VP-2, was designed to be a racing game that would be simple to create to fulfill an earlier contract with Bally Midway; Atari had initially offered "Pong" during its development to fulfill the contract, but had been rejected. The company was also interested in producing a very different game from their previous success, as they felt that innovative design was what would separate them from their competitors, which they saw as flooding the market with "Pong" clones rather than making new video games.
Space Invaders
The 1980 Atari 2600 version was the first official licensing of an arcade game and became the first "killer app" for video game consoles by quadrupling the system's sales. It sold over two million units in its first year on sale as a home console game, making it the first title to sell a million cartridges. Other official ports were released for the Atari 8-bit computer line and Atari 5200 console, while Taito later released it for the Nintendo Famicom in 1985 (Japan only). Numerous unofficial clones were made, such as the popular computer games "Super Invader" (1979) and "TI Invaders" (1981), which was the top-selling game for the Texas Instruments TI-99/4A through at least 1982. Adjusted for inflation, all versions of "Space Invaders" are estimated to have exceeded $13 billion in gross revenue, making it the highest-grossing video game of all time.
