History

The history of online games dates back to the early days of packet-based computer networking in the 1970s, An early example of online games are MUDs, including the first, MUD1, which was created in 1978 and originally confined to an internal network before becoming connected to ARPANet in 1980. Commercial games followed in the next decade, with Islands of Kesmai, the first commercial online role-playing game, debuting in 1984, as well as more graphical games, such as the MSX LINKS action games in 1986, the flight simulator Air Warrior in 1987, and the Famicom Modem's online Go game in 1987.

The rapid availability of the Internet in the 1990s led to an expansion of online games, with notable titles including Nexus: The Kingdom of the Winds (1996), Quakeworld (1996), Ultima Online (1997), Lineage (1998), Starcraft (1998), Counter-Strike (1999) and EverQuest (1999). Video game consoles also began to receive online networking features, such as the Famicom Modem (1987), Sega Meganet (1990), Satellaview (1995), SegaNet (1996), PlayStation 2 (2000) and Xbox (2001). Following improvements in connection speeds, more recent developments include the popularization of new genres, such as social games, and new platforms, such as mobile games.better source needed

Entering into the 2000s, the cost of technology, servers and the Internet has dropped so far that fast Internet was commonplace, which led to previously unknown genres like massively multiplayer online games (MMOs) becoming well-known. For example, World of Warcraft (2004) dominated much of the decade. Several other MMOs attempted to follow in Warcraft's footsteps, such as Star Wars Galaxies, City of Heroes, Wildstar, Warhammer Online, Guild Wars 2, and Star Wars: The Old Republic, but failed to make a significant impact in Warcraft's market share. Over time, the MMORPG community has developed a sub-culture with its own slang and metaphors, as well as an unwritten list of social rules and taboos.

Separately, a new type of online game came to popularity alongside World of Warcraft, Defense of the Ancients (2003) which introduced the multiplayer online battle arena (MOBA) format. DotA, a community mod based on Warcraft III, gained in popularity as interest in World of Warcraft waned, but since the format was tied to the Warcraft property, others began to develop their own MOBAs, including Heroes of Newerth (2009), League of Legends (2010), and Dota 2 (2013). Blizzard Entertainment, the owner of Warcraft property, released their own take on the MOBA genre with Heroes of the Storm (2015), emphasizing on numerous original heroes from Warcraft III and other Blizzard's franchises. By the early 2010s, the genre has become a big part of the esports category.

In the late 2010s, the battle royale game format became widely popular with the release of PlayerUnknown's Battlegrounds (2017), Fortnite Battle Royale (2017), and Apex Legends (2019). Popularity of the genre continued in 2020s with the release of the Call of Duty: Warzone (2020). Each game has received tens of millions of players within months of their releases.
