Galaxian
Galaxian was produced by Namco in 1979 as a response to the success of Space Invaders, released by Taito a year prior, which had a large impact on the video game industry and helped establish video games as a highly-profitable business.
Galaxian was a surprise hit for Namco, and sold around 40,000 arcade units in North America by 1982. Galaxian had RGB color graphics integrated into animations and enemy
explosions, as well as scrolling backgrounds and short jingles. While not the first video game to introduce color, Galaxian was the first video game released with 100 percent of its graphics displayed in true RGB color. All color arcade games prior to Galaxian faked the color by applying colored strips to the screen of a black and white display.
