An arcade game or coin-op is a coin-operated entertainment machine typically installed in public businesses such as restaurants, bars and amusement arcades. Most arcade games are video games, pinball machines, electro-mechanical games, redemption games or merchandisers. While exact dates are debated, the golden age of arcade video games is usually defined as a period beginning sometime in the late 1970s and ending sometime in the mid-1980s. Excluding a brief resurgence in the early 1990s, the arcade industry subsequently declined in the Western hemisphere as competing home-based video game consoles such as Playstation and Xbox increased in their graphics and game-play capability and decreased in cost.
The first popular "arcade games" included early amusement-park midway games such as , ball- games, and the earliest coin-operated machines, such as those that claimed to tell a person's fortune or that played mechanical music. The old Midways of 1920s-era amusement parks (such as Coney Island in New York) provided the inspiration and atmosphere for later arcade games. In the 1930s the first coin-operated pinball machines emerged. These early amusement machines differed from their later electronic cousins in that they were made of wood. They lacked plungers or lit-up bonus surfaces on the playing field, and used mechanical instead of electronic scoring-readouts. By around 1977 most pinball machines in production switched to using solid-state electronics both for operation and for scoring.
