The Neo Geo, stylized as NEO•GEO, is a video game platform released in 1990 by Japanese game company SNK Corporation. It was initially released in two ROM cartridge-based formats: an arcade system board and a home video game console. A CD-ROM-based home console iteration, the Neo Geo CD, was released in 1994. The arcade system can hold multiple cartridges that can be exchanged out, a unique feature that contrasted to the dedicated single-game arcade cabinets of its time, making it popular with arcade operators.
