The 3DO Company (formerly THDO on the NASDAQ stock exchange), also known as 3DO, was a video game company. It was founded in 1991 under the name SMSG, Inc. (for San Mateo Software Group) by Electronic Arts co-founder Trip Hawkins in a partnership with seven other companies, including LG, Matsushita, AT&T, MCA, Time Warner, and Electronic Arts. After the 3DO Company's flagship video game console, the 3DO Interactive Multiplayer failed in the marketplace, the company exited the hardware business and became a third-party video game developer.
