In the late 1970s, Nintendo Co., Ltd. began shifting their focus away from toys and playing cards into the arcade market. This followed the 1973 oil crisis having increased the cost of manufacturing toys, and the widespread success of Taito's "Space Invaders" in 1978. Nintendo had briefly experimented with electro-mechanical arcade gun games such as "Wild Gunman" and the "Laser Clay Shooting System", followed by arcade video games such as "EVR-Race", "Sheriff", "Space Fever", and the Color TV Game line of dedicated home consoles.
