A massively multiplayer online game (also called MMOG or simply MMO) is a video game which is capable of supporting hundreds or thousands of players simultaneously.
AI-controlled characters are not as common in action-based MMOGs.
The popularity of MMOGs was mostly restricted to the computer game market until the sixth-generation consoles, with the launch of Phantasy Star Online on Dreamcast and the emergence and growth of online service Xbox Live.
The first graphical MMOG, and a major milestone in the creation of the genre, was the multi-player flight combat simulation game Air Warrior by Kesmai on the GEnie online service, which first appeared in 1987.
Commercial MMORPGs gained early acceptance in the late 1980s and early 1990s.
MMOGs have only recently begun to break into the mobile phone market.
The first, Samurai Romanesque set in feudal Japan, was released in 2001 on NTT Do Co Mo's i Mode network in Japan.
The most popular type of MMO, and the sub-genre that pioneered the category, is the massively multiplayer online role playing game (MMORPG), which descended from university mainframe computer MUD and adventure games such as Rogue, Dungeon on the PDP-10; and Devious MUD, which later turned into the successful game Rune Scape.
These games predate the commercial gaming industry and the Internet, but still featured persistent worlds and other elements of MMOGs still used today.
