Space Invaders is considered one of the most influential video games of all time. It helped expand the video game industry from a novelty to a global industry, and ushered in the golden age of arcade video games. It was the inspiration for numerous video games and game designers across different genres, and has been ported and re-released in various forms. The 1980 VCS version quadrupled sales of the VCS, thereby becoming the first killer app for video game consoles. More broadly, the pixelated enemy alien has become a pop culture icon, often representing video games as a whole.
