Platforms in Competitive Gaming
All platforms support competition in some form. The Space Invaders Championship held by Atari in 1981 was the earliest large scale video game competition. Players would compete for the highest scores.

The tournaments which emerged in the mid 1990s coincided with the popularity of fighting games, played in both arcade machines and video game consoles. In the late 1990s, broadband internet paved the way for first-person shooters tournaments on PC, the most notable being the Red Annihilation tournament in 1997 where Dennis "Thresh" Fong won John Carmack's Ferrari. In the early 2000s, real-time strategy games on PC became overwhelmingly popular in South Korean internet cafés, with crucial influence on the development of competitive gaming worldwide.

As of August 16, 2014, the largest platform for competitive gaming is PC, with the games Dota 2, League of Legends, StarCraft II, and Counter-Strike: Global Offensive. Over $22 million has been awarded in Dota 2 competitions. Various Nintendo Games (played on Nintendo Consoles with local, LAN or Online Multiplayer) and the latest iteration of the Call of Duty franchise are popular on consoles.
