Video game genres were still being established, but included space-themed shooter games such as Defender and Galaga, maze chase games that followed the design established by Pac-Man, driving and racing games which more frequently used 3D perspectives such as Turbo and Pole Position, character action games such as Pac-Man and Frogger, and the beginning of what would later be called platform games touched off by Donkey Kong. Video game arcades became a part of popular culture and a primary channel for new games. Arcade video games switched from black-and-white to color, with titles such as Frogger and Centipede taking advantage of the visual opportunities of bright palettes. The release of Space Invaders in 1978 led to a wave of shoot-'em-up games such as Galaxian and the vector graphics-based Asteroids in 1979, made possible by new computing technology that had greater power and lower costs. The golden age of arcade video games was the period of rapid growth, technological development, and cultural influence of arcade video games from the late 1970s to the early 1980s.
