The genre was pioneered by the Gem Stone series on GEnie, also created by Kesmai, and Neverwinter Nights, the first such game to include graphics, which debuted on AOL in 1991.
As computer game developers applied MMO ideas to other computer and video game genres, new acronyms started to develop, such as MMORTS.
They are, however, not necessarily games played on personal computers.
Most of the newer game consoles, including the Xbox 360, Play Station Portable, Play Station 3, Nintendo DS and Wii can access the Internet and run MMO games.

MMOGs emerged from the hard-core gamer community to the mainstream strongly in December 2003 with an analysis in the Financial Times measuring the value of the virtual property in the then-largest MMOG, Everquest, to result in a per-capita GDP of 2,266 dollars which would have placed the virtual world of Everquest as the 77th wealthiest nation, on par with Croatia, Ecuador, Tunisia or Vietnam.The debuts of The Realm Online, Meridian 59 (the first 3D MMOG), Ultima Online, Underlight and Ever Quest in the late 1990s popularized the MMORPG genre. Despite the genre's focus on multiplayer gaming, AI-controlled characters are still common.The growth in technology meant that where Neverwinter Nights in 1991 had been limited to 50 simultaneous players (a number that grew to 500 by 1995), by the year 2000 a multitude of MMORPGs were each serving thousands of simultaneous players and in December 2007 Eve Online achieved a new record with "41,690". NPCs and mobs who give out quests or serve as opponents are typical mostly in MMORPGs.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.
