The 3DO Interactive Multiplayer (3DO) is a fifth-generation console and was first released in the United States in 1993. It was originally manufactured by Panasonic, and was later modified by GoldStar and Sanyo. It was among the first generation of consoles to use CD-ROMs instead of cartridges, and some of its most popular titles were ports from arcade and computer games that would not be supported on cartridges. Despite its progressive technology, 3DO could not compete with its top rivals, the Sony PlayStation, the Sega Saturn, and Nintendo's N64 - even though the latter still used cartridges. Its high purchase price of $699.95 also deterred would-be buyers, and the system was discontinued in 1996. The 3DO company then focused exclusively on software development, publishing many popular titles for the PlayStation, Saturn and PC, including StarFighter and the Army Men series.
