Early history of video games
Throughout the rest of the 1960s, digital computer games were created by increasingly numerous programmers and sometimes sold commercially in catalogs. As the audience for video games expanded to more than a few dozen research institutions with the falling cost of computers, and programming languages that would run on multiple types of computers were created, a wider variety of games began to be developed. Video games transitioned into a new era in the early 1970s with the launch of the commercial video game industry in 1971 with the display of the coin-operated arcade game "Galaxy Game" and the release of the first arcade video game "Computer Space", and then in 1972 with the release of the immensely successful arcade game "Pong" and the first home video game console, the Magnavox Odyssey, which launched the first generation of video game consoles.
Donkey Kong (video game)
"Donkey Kong" is considered to be the earliest video game with a storyline that visually unfolds on screen. The eponymous Donkey Kong character is the game's "de facto" villain. The hero is a carpenter originally unnamed in the Japanese arcade release, later named Jumpman and then Mario. Donkey Kong kidnaps Mario's girlfriend, originally known as Lady, but later renamed Pauline. The player must take the role of Mario and rescue her. This is the first occurrence of the damsel in distress scenario that would provide the template for countless video games to come.
